  • JavaScript onClick() Display

    - by junaidkaps
    I have an array consisting of several objects containing Strings. I am successfully able to display the array by using: <td><p onclick="theMiddle(this)">The Middle</td> As you see from the td tag this is part of a table. Issue is that the browser opens up a new page to display my text. I have been trying to display the array above my table in a p tag. //JavaScript var arrayTheMiddle = new Array (showName.theMiddle, beginingTime.theMiddle, network.abc, duration.thirty, rating.general, description.theMiddle, showImage.theMiddle); function theMiddle(obj){ for(i=0; i < arrayTheMiddle.length; i++) { document.write(arrayTheMiddle[i] + "<br>"); } } //HTML File <p>Would like the array/function displayed here while the user clicks within the table below (entire table has not been listed)</p> <td><p onclick="theMiddle(this)">The Middle</td> Unfortunately I am constantly failing at utilizing get element by id to call my function which consists of an array. I have searched for all sorts of stuff, yet frankly I'm lost. Not even sure if my approach is correct at this point. I'm sure this is one of those simple things that are blowing over my head!

  • Groovy htmlunit getFirstByXPath returning null

    - by StartingGroovy
    I have had a few issues with HtmlUnit returning nulls lately and am looking for guidance. each of my results for grabbing the first row of a website have returned null. I am wondering if someone can A) explain why they might be returning null B) explain better ways (if there are some) to go about getting the information Here is my current code (URL is in the source): client = new WebClient(BrowserVersion.FIREFOX_3) client.javaScriptEnabled = false def url = "http://www.hidemyass.com/proxy-list/" page = client.getPage(url) IpAddress = page.getFirstByXPath("//html/body/div/div/form/table/tbody/tr/td[2]").getValue() println "IP Address is: $data" //returns null //Port_Number is an Image Country = page.getFirstByXPath("//html/body/div/div/form/table/tbody/tr/td[4][@class='country']/@rel").getValue() println "Country abbreviation is: $Country" //differentiate speed and connection by name of gif? Type = page.getFirstByXPath("//html/body/div/div/form/table/tbody/tr/td[7]").getValue() println "Proxy type is: $Type" Anonymity = page.getFirstByXPath("//html/body/div/div/form/table/tbody/tr/td[8]").getValue() println "Anonymity Level is: $Anonymity" client.closeAllWindows() Right now all of my XPaths return null and .getValue() obviously doesn't work on null. I also have questions as to what I should do about the PORT since it is an image? Is there a better alternative than downloading it and attempting to solve it by OCR? Side Note There is no significance in this site, I was just looking for a site that I could practice scraping on (the last one I ran into issues of fragment identities and couldn't get an answer to: HtmlUnit getByXpath returns null and HtmlUnit and Fragment Identities )

  • Mapping over multiple Seq in Scala

    - by bsdfish
    Suppose I have val foo : Seq[Double] = ... val bar : Seq[Double] = ... and I wish to produce a seq where the baz(i) = foo(i) + bar(i). One way I can think of to do this is val baz : Seq[Double] = (foo.toList zip bar.toList) map ((f: Double, b : Double) => f+b) However, this feels both ugly and inefficient -- I have to convert both seqs to lists (which explodes with lazy lists), create this temporary list of tuples, only to map over it and let it be GCed. Maybe streams solve the lazy problem, but in any case, this feels like unnecessarily ugly. In lisp, the map function would map over multiple sequences. I would write (mapcar (lambda (f b) (+ f b)) foo bar) And no temporary lists would get created anywhere. Is there a map-over-multiple-lists function in Scala, or is zip combined with destructuring really the 'right' way to do this?

  • Sql Compact and __sysobjects

    - by Scott Wisniewski
    I have some SQL Compact queries that create tables inside of transaction. This is mainly because I need to simulate temporary tables, which SQL Compact does not support. I do this by creating a real table, and then dropping it at the end of the transaction. This mostly works. Sometimes, however, when creating the tables Sql Compact will try to acquire PAGE level locks on the __sysobjects table. If there are several concurrent queries running that create "temp" tables, the attempt to acquire a page lock can result in a dead lock followed by a SqlLockTimeout exception. For normal tables I could fix this using a "with (rowlock)" hint. However, because I'm not writing the query to insert into __sysobjets (SQL server does that in response to "create table") I can't do this. Does anyone know of a way I could get around this? I've thought about pulling the table creation out of the transaction, but that opens up the possibility of phantom temporary tables that I'd then need to clean up regularly. Ideally I'd like to avoid that if possible.

  • Foreign key relationships in Entity Framework

    - by Anders Svensson
    I'm trying to add an object created from Entity Data Model classes. I have a table called Users, which has turned into a User EDM class. And I also have a table Pages, which has become a Page EDM class. These tables have a foreign key relationship, so that each page is associated with many users. Now I want to be able to add a page, but I can't get how to do it. I get a nullreference exception on Users below. I'm still rather confused by all this, so I'm sure it's a simple error, but I just can't see how to do it. Also, by the way, the compiler requires that I set PageID in the object initializer, even though this field is set to be an automatic id in the table. Am I doing it right just setting it to 0, expecting it to be updated automatically in the table when saved, or how should I do that? Any help appreciated! The method in question: private Page GetPage(User currentUser) { string url = _request.ServerVariables["url"].ToLower(); var userPages = from p in _context.PageSet where p.Users.UserID == currentUser.UserID select p; var existingPage = userPages.FirstOrDefault(e => e.Url == url); //Could be combined with above, but hard to read? if (existingPage != null) return existingPage; Page page = new Page() { Count = 0, Url = _request.ServerVariables["url"].ToLower(), PageID = 0, //Only initial value, changed later? }; _context.AddToPageSet(page); page.Users.UserID = currentUser.UserID; //Here's the problem... return page; }

  • Why trigger query fails in the sqlite with Qt?

    - by dexterous_stranger
    I am a beginner in the SQL. I am using SQLite, Qt - on embedded systems. I want to put a trigger here. The trigger is that whenever the primary key Id is greater than 32145, then channelNum=101 should be set. I want to set the attrib name - text also, but I got the compilation issue. I believe that the setting of trigger is the part of DDL - Data definition language. Please let me know that if I am wrong here. Here is my create db code. I get the sql query error. Also please do suggest how to set the text attrib = "COmedy". /** associate db with query **/ QSqlQuery query ( m_demo_db ); /** Foreign keys are disabled by default in sqlite **/ /** Here is the pragma to turn them on first **/ query.exec("PRAGMA foreign_keys = ON;"); if ( false == query.exec()) { qDebug()<<"Pragma failed"; } /** Create Table for storing user preference LCN for DTT **/ qDebug()<<"Create Table postcode.db"; query.prepare(" CREATE TABLE dttServiceList (Id INTEGER PRIMARY KEY, attrib varchar(20), channelNum integer )" ); if ( false == query.exec()) { qDebug()<<"Create dttServiceList table failed"; } /** Try placing trigger here **/ triggerQuery = "CREATE TRIGGER upd_check BEFORE INSERT ON dttServiceList \ FOR EACH ROW \ BEGIN \ IF Id > 32145 THEN SET channelNum=101; \ END IF; \ END; "; query.prepare(triggerQuery); if ( false == query.exec()) { qDebug()<<"Trigger failed !!"; qDebug() << query.lastError(); } Also, how to set the text name in the trigger - I want to SET attrib = "Comedy".

  • SQLAlchemy, one to many vs many to one

    - by sadvaw
    Dear Everyone, I have the following data: CREATE TABLE `groups` ( `bookID` INT NOT NULL, `groupID` INT NOT NULL, PRIMARY KEY(`bookID`), KEY( `groupID`) ); and a book table which basically has books( bookID, name, ... ), but WITHOUT groupID. There is no way for me to determine what the groupID is at the time of the insert for books. I want to do this in sqlalchemy. Hence I tried mapping Book to the books joined with groups on book.bookID=groups.bookID. I made the following: tb_groups = Table( 'groups', metadata, Column('bookID', Integer, ForeignKey('books.bookID'), primary_key=True ), Column('groupID', Integer), ) tb_books = Table( 'books', metadata, Column('bookID', Integer, primary_key=True), tb_joinedBookGroup = sql.join( tb_books, tb_groups, \ tb_books.c.bookID == tb_groups.c.bookID) and defined the following mapper: mapper( Group, tb_groups, properties={ 'books': relation(Book, backref='group') }) mapper( Book, tb_joinedBookGroup ) ... However, when I execute this piece of code, I realized that each book object has a field groups, which is a list, and each group object has books field which is a singular assigment. I think my definition here must have been causing sqlalchemy to be confused about the many-to-one vs one-to-many relationship. Can someone help me sort this out? My desired goal is g.books = [b, b, b, .. ] book.group = g, where g is an instance of group, and b is an instance of book

  • SQLCe local db in temp- path in connectionstring?

    - by Petr
    Hi, I have SQL Ce db in my app, which is included in my app directory. While debugging its OK, but when published and run with setup.exe, it retrieves "file not found" in temporary directory the app is ran from. I would like to run from standard location, but I dont know how to change it. I am using this string: SqlCeConnection connection = new SqlCeConnection("Data Source=database.sdf;Persist Security Info=False;"); When I run setup.exe, the app never starts, stating that in its temporary directory the db file was not found. When I run app.exe, it works. I do not understand it...:( EDIT: I can see that in the VS project settings, there is connection string and there is "Data Source=|DataDirectory|\Database.sdf" The path should be something like local directory? Thanks!

  • Binding value for NSTableView, but tooltip gets set as well

    - by Mark
    I've set up an NSTableView in Interface Builder to be populated from an NSArray. Each value of the array represents one row in the table. The value is bound correctly, but as a side effect, the table cell's tooltip is set to the string representation of the bound object. In my case, the NSArray contains NSDictiorany objects and the tooltip looks like it could be the [... description] output of that dictionary. Very ugly... I don't want the tooltip to be set at all. I have other tables that have plain NSString values bound to them and they don't have a tooltip set automatically. Is there some Interface Builder magic going on? I tried to start with a blank project - same problem. I should add that the table cell is a custom implementation of NSTextFieldCell that uses an NSButtonCell instance to draw an image and a label into the table. The values are retrieved from the dictionary bound as value. Why is the tooltip set when I only bind the "value" attribute? Thanks in advance!

  • problem in handling menu - submenu based on spring security

    - by Nirmal
    Hi All... I have configured spring security core plugin using requestmap table inside the database.. Now inside requestmap table I have all the possible urls and it's equivalent roles who can access that url... Now I want to generate menus and submenus based on the urls stored in requestmap table... So my requirement is to check the urls of menu & submenus against the logged in users privileges... And if logged in user has any one privilege then I need to display that main menu and the available submenus.... For e.g. I have a menu in my project called user which has a following submenus : **Users (main menu)** Manage Users (sub menu) Import Users (sub menu) Now inside my header.gsp I have successfully achieved the above requirement using if else condition, like : if ( privs.contains("/users/manageUsers") || privs.contains("/users/importUsers")) here privs are the list of urls from requestmap table for logged in user. But I want to achieve these using spring security tag lib, so for comparing urls I have find following tag from spring security core documentation : <sec:access url="/users/manageUsers"> But i am bit confuse that how I can replace or condition using tag library.. Is there any tag available which checks from multiple urls and evaluate it to true or false ? Of course I can do using sec:access tag with some flag logic, but is there any tags available which can fulfill my requirement directly ? Thanks in advance...

  • jQuery selector selecting all rows... why?

    - by Jagd
    I have a standard HTML table that looks something like this in structure: <table> <tbody> <tr> <td>FOOTER</td> <td> ... other td columns </td> </tr> <tr> <td>some other row that I don't want selected</td> <td> ... other td columns </td> </tr> </tbody> </table> What I would like to do is select only the tr's that contain the text FOOTER in a td, and then set the font-weight to bold for all td's under the selected tr's. My problem is that the jQuery selector I have is setting all td's within the table to bold and I'm not sure why. Here's my selector thus far: $("tr:contains('FOOTER')").children("td").css("font-weight", "bold");

  • How to initialise a STL vector/list with a class without invoking the copy constructor

    - by Warpspace
    I have a C++ program that uses a std::list containing instances of a class. If I call e.g. myList.push_back(MyClass(variable)); it goes through the process of creating a temporary variable, and then immediately copies it to the vector, and afterwards deletes the temporary variable. This is not nearly as efficient as I want, and sucks when you need a deep copy. I would love to have the constructor of my class new something and not have to implement a copy constructor just to allocate my memory for the second time and waste runtime. I'd also rather not have to immediately find the class instance from the vector/list and then manually allocate the memory (or do something horrible like allocate the memory in the copy constructor itself). Is there any way around this (I'm not using Visual Studio BTW)?

  • Sanitize input before executing at server in php

    - by Interfaith
    I want to let user input two variable, Name and Password in a form. I want to disable any XSS or script insert in the input values. I have the following code in the form method: <form name="form1" method="post" action="checkpw.php"> Your Name: <table> <tr><td><input class="text" name="name" onBlur="capitalize(this);" maxlength=12 type="text" /></td></tr> </table> Password: <table> <tr><td><input class="text" name="passwd" maxlength=8 type="password" /></td></tr> <tr><td align="center"><br/> <input class="text" type="submit" name="submitbt" value="Login" /> </td></tr> </table> and the following checkpw.php: <?php // Clean up the input values $post = filter_input_array(INPUT_POST, array( 'name' => FILTER_SANITIZE_STRING, 'pw' => FILTER_SANITIZE_STRING, )); if (is_null($post) || in_array(null, $post)) { header("location:login.php"); return; // missing fields (or failed filter) } // pw is the password sent from the form $pw=$_POST['passwd']; $name=$_POST['name']; if($pw == 'testpass'){ header("location:index.php"); } else { header("location:wrong.php"); } ?> Is this a secure way to ensure the form is sent to the server and executed ONLY after the input values have been sanitized? Also, the $name value i want to pass it to index.php file. I insert a code in the index.php as follow: <?php echo $name ?> But it's empty. Any idea how to resolve it?

  • incorrect height in Chrome when "-webkit-appearance: none" and value="" on <input> tag

    - by Avi Steiner
    In Chrome v17.0.963.79 on Windows 7, I seem to be having an inexplicable problem when applying the -webkit-appearance: none style to an <input> tag. The problem is as follows: I have a stylesheet, let's call it potatofoot.css, which consists of the code .tbl { display: table; } .tblRow { display: table-row; } .tblCell { display: table-cell; } input { -webkit-appearance: none; }? and I have an html file, let's call it blech.html, which contains the code <div class="tbl"> <div class="tblRow"> <label class="tblCell">Name</label> <input type="text" class="tblCell" value="I'M NOT EMPTY! OH, YEAH!"> </div><!--end tblRow--> </div><!--end tbl--> This displays fine (see this jsfiddle). But when I empty the value attribute, as in this jsfiddle, the entire table grows from a height of 26px to a height of 31px, the label moves to the bottom, and the input stays at the top. However, if I remove -webkit-appearance: none;, everything shows up the same with and without out the value attribute being filled. What's going on?

  • JOIN (SELECT DISTINCT [..] substitute

    - by FRKT
    Hello, I'd like to find a substitute for using SELECT DISTINCT in a derived table. Let's say I have three tables: CREATE TABLE `trades` ( `tradeID` int(11) unsigned NOT NULL AUTO_INCREMENT, `employeeID` int(11) unsigned NOT NULL, `corporationID` int(11) unsigned NOT NULL, `profit` int(11) NOT NULL, KEY `tradeID` (`tradeID`), KEY `employeeID` (`employeeID`), KEY `corporationID` (`corporationID`) ) ENGINE=MyISAM DEFAULT CHARSET=latin1 CREATE TABLE `corporations` ( `corporationID` int(11) unsigned NOT NULL AUTO_INCREMENT, `name` varchar(255) NOT NULL, PRIMARY KEY (`corporationID`) ) ENGINE=MyISAM DEFAULT CHARSET=latin1 CREATE TABLE `employees` ( `employeeID` int(11) unsigned NOT NULL AUTO_INCREMENT, `name` varchar(255) NOT NULL, PRIMARY KEY (`employeeID`) ) ENGINE=MyISAM DEFAULT CHARSET=latin1 Let's say I'd like to find out how much profit a specific employee has generated. Simple: SELECT SUM(profit) FROM trades JOIN employees ON trades.employeeID = employees.employeeID AND employees.employeeID = 1; It gets trickier if I'd like to query how much revenue a specific corporation has, however. I cannot simply replicate the aforementioned query, because two or more employees from the same company might be involved in the same trade. This query should do the trick: SELECT SUM(profit) FROM trades JOIN (SELECT DISTINCT tradeID FROM trades WHERE trades.corporationID = 1) ... unfortunately, DISTINCT JOINs seem crazy ineffective. Is there any alternative I can use to determine how much revenue a corporation has, taking into account that a corporation might be listed several times with the same tradeID?

  • Core Data object into an NSDictionary with possible nil objects

    - by Chuck
    I have a core data object that has a bunch of optional values. I'm pushing a table view controller and passing it a reference to the object so I can display its contents in a table view. Because I want the table view displayed a specific way, I am storing the values from the core data object into an array of dictionaries then using the array to populate the table view. This works great, and I got editing and saving working properly. (i'm not using a fetched results controller because I don't have anything to sort on) The issue with my current code is that if one of the items in the object is missing, then I end up trying to put nil into the dictionary, which won't work. I'm looking for a clean way to handle this, I could do the following, but I can't help but feeling like there's a better way. *passedEntry is the core data object handed to the view controller when it is pushed, lets say it contains firstName, lastName, and age, all optional. if ([passedEntry firstName] != nil) { [dictionary setObject:[passedEntry firstName] forKey:@"firstName"] } else { [dictionary setObject:@"" forKey:@"firstName"] } And so on. This works, but it feels kludgy, especially if I end up adding more items to the core data object down the road.

  • How can I use a compound condition in a join in Linq?

    - by Gary McGill
    Let's say I have a Customer table which has a PrimaryContactId field and a SecondaryContactId field. Both of these are foreign keys that reference the Contact table. For any given customer, either one or two contacts may be stored. In other words, PrimaryContactId can never be NULL, but SecondaryContactId can be NULL. If I drop my Customer and Contact tables onto the "Linq to SQL Classes" design surface, the class builder will spot the two FK relationships from the Customer table to the Contact table, and so the generated Customer class will have a Contact field and a Contact1 field (which I can rename to PrimaryContact and SecondaryContact to avoid confusion). Now suppose that I want to get details of all the contacts for a given set of customers. If there was always exactly one contact then I could write something like: from customer in customers join contact in contacts on customer.PrimaryContactId equals contact.id select ... ...which would be translated into something like: SELECT ... FROM Customer INNER JOIN Contact ON Customer.FirstSalesPersonId = Contact.id But, because I want to join on both the contact fields, I want the SQL to look something like: SELECT ... FROM Customer INNER JOIN Contact ON Customer.FirstSalesPersonId = Contact.id OR Customer.SecondSalesPersonId = Contact.id How can I write a Linq expression to do that?

  • How can I efficiently manipulate 500k records in SQL Server 2005?

    - by cdeszaq
    I am getting a large text file of updated information from a customer that contains updates for 500,000 users. However, as I am processing this file, I often am running into SQL Server timeout errors. Here's the process I follow in my VB application that processes the data (in general): Delete all records from temporary table (to remove last month's data) (eg. DELETE * FROM tempTable) Rip text file into the temp table Fill in extra information into the temp table, such as their organization_id, their user_id, group_code, etc. Update the data in the real tables based on the data computed in the temp table The problem is that I often run commands like UPDATE tempTable SET user_id = (SELECT user_id FROM myUsers WHERE external_id = tempTable.external_id) and these commands frequently time out. I have tried bumping the timeouts up to as far as 10 minutes, but they still fail. Now, I realize that 500k rows is no small number of rows to manipulate, but I would think that a database purported to be able to handle millions and millions of rows should be able to cope with 500k pretty easily. Am I doing something wrong with how I am going about processing this data? Please help. Any and all suggestions welcome.

  • Can't add/remove items from a collection while foreach is iterating over it

    - by flockofcode
    If I make my own implementation of IEnumerator interface, then I am able ( inside foreach statement )to add or remove items from a albumsList without generating an exception.But if foreach statement uses IEnumerator supplied by albumsList, then trying to add/delete ( inside the foreach )items from albumsList will result in exception: class Program { static void Main(string[] args) { string[] rockAlbums = { "rock", "roll", "rain dogs" }; ArrayList albumsList = new ArrayList(rockAlbums); AlbumsCollection ac = new AlbumsCollection(albumsList); foreach (string item in ac) { Console.WriteLine(item); albumsList.Remove(item); //works } foreach (string item in albumsList) { albumsList.Remove(item); //exception } } class MyEnumerator : IEnumerator { ArrayList table; int _current = -1; public Object Current { get { return table[_current]; } } public bool MoveNext() { if (_current + 1 < table.Count) { _current++; return true; } else return false; } public void Reset() { _current = -1; } public MyEnumerator(ArrayList albums) { this.table = albums; } } class AlbumsCollection : IEnumerable { public ArrayList albums; public IEnumerator GetEnumerator() { return new MyEnumerator(this.albums); } public AlbumsCollection(ArrayList albums) { this.albums = albums; } } } a) I assume code that throws exception ( when using IEnumerator implementation A supplied by albumsList ) is located inside A? b) If I want to be able to add/remove items from a collection ( while foreach is iterating over it), will I always need to provide my own implementation of IEnumerator interface, or can albumsList be set to allow adding/removing items? thank you

    Hey i got this Table: CREATE TABLE Test_Table ( old_val VARCHAR2(3), new_val VARCHAR2(3), Updflag NUMBER, WorkNo NUMBER ); and this is in my Table: INSERT INTO Test_Table (old_val, new_val, Updflag , WorkNo) VALUES('1',' 20',0,0); INSERT INTO Test_Table (old_val, new_val, Updflag , WorkNo) VALUES('2',' 20',0,0); INSERT INTO Test_Table (old_val, new_val, Updflag , WorkNo) VALUES('2',' 30',0,0); INSERT INTO Test_Table (old_val, new_val, Updflag , WorkNo) VALUES('3',' 30',0,0); INSERT INTO Test_Table (old_val, new_val, Updflag , WorkNo) VALUES('4',' 40',0,0); INSERT INTO Test_Table (old_val, new_val, Updflag , WorkNo) VALUES('4',' 40',0,0); now my Table Looks like this: Row Old_val New_val Updflag WorkNo 1 '1' ' 20' 0 0 2 '2' ' 20' 0 0 3 '2' ' 30' 0 0 4 '3' ' 30' 0 0 5 '4' ' 40' 0 0 6 '5' ' 40' 0 0 (if the value in the new_val column are same then they are together and the same goes to old_val) so in the example above row 1-4 are together and row 5-6 at the moment i have in my Stored Procedure a cursor: SELECT t1.Old_val, t1.New_val, t1.updflag, t1.WorkNo FROM Test_Table t1 WHERE t1.New_val = ( SELECT t2.New_val FROM Test_Table t2 WHERE t2.Updflag = 0 AND t2.Worknr = 0 AND ROWNUM = 1 ) the output is this: Row Old_val New_val Updflag WorkNo 1 1 20 0 0 2 2 20 0 0 my Problem is, i dont know how to get row 1 to 4 with one select. (i had an idea with 4 sub-querys but this wont work if its more data that matches together) does anyone of you have an idea?

  • tbody td borders not scrolling with content in tbody overflow:auto;

    - by tester
    I am unable to get the borders of these td's to follow their rows as I scroll through this overflow:auto; . Any ideas on a fix? Note: Setting table-layout:fixed or making rows display:block isn't an option as the rows will lose their fluidity.. You can see the issue in the latest Firefox, so I assume it's messed up elsewhere. Here is a test I setup (scroll to the bottom for the demo): http://www.webdevout.net/test?01y HTML: <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> <html lang="en"> <head> <title>Test</title> </head> <body> <table> <thead><th>One</th><th>Two</th><th>Three</th></thead> <tbody> <tr><td>Item</td><td>Item</td><td>Item</td></tr> <tr><td>Item</td><td>Item</td><td>Item</td></tr> <tr><td>Item</td><td>Item</td><td>Item</td></tr> <tr><td>Item</td><td>Item</td><td>Item</td></tr> </tbody> </table> </body> </html> CSS: table {width:100%;border-collapse:collapse;} tbody {height:200px;overflow:auto;} td {border-bottom:1px solid #f00;}

  • how to add data to ARRAYLIST

    - by Chamal
    try { ArrayList ar=new ArrayList(); PRIvariable pri=new PRIvariable(); BufferedReader reader = new BufferedReader(new InputStreamReader(new FileInputStream("C:/cdr2.csv"))); while (reader.ready()) { String line = reader.readLine(); String[] values = line.split(","); pri.dateText=values[2]+" "+values[4]; pri.count=pri.count+1; pri.sum = pri.sum+Integer.parseInt(values[7]); System.out.println(pri.dateText+" "+pri.sum+" "+pri.count); ar.add(pri); } String[] columnNames={"Date","TOTAL","COUNTS"}; String[][] cells=new String[ar.size()][3]; for(int i=0;i<ar.size();i++){ cells[i][0]=((PRIvariable)ar.get(i)).dateText; cells[i][1]=""+((PRIvariable)ar.get(i)).sum; cells[i][2]=""+((PRIvariable)ar.get(i)).count; } table = new JTable(cells,columnNames); table.setSize(400,400); table.setVisible(true); JScrollPane js=new JScrollPane(); js.setViewportView(table); js.setSize(400,400); js.setVisible(true); add(js,java.awt.BorderLayout.CENTER); } catch (Exception e) { System.out.println(e); } This is my code. Here i want to Read text file and put that data to Jtable. But in this code it shows every row of the Jtable filled with same data that contain in arraylist(ar) last row. ( i think there is problem in my arraylist). How can i solve this......
