  • Why Java as a First Language?

    - by dsimcha
    Why is Java so popular as a first language to teach beginners? To me it seems like a terrible choice: It's statically typed. Static typing isn't useful unless you care a lot about either performance or scaling to large projects. It requires tons of boilerplate to get the simplest code up and running. Try explaining "Hello, world" to someone who's never programmed before. It only handles the middle levels of abstraction well and is single-paradigm, thus leaving out a lot of important concepts. You can't program at a very low level (pointers, manual memory management) or a very high level, (metaprogramming, macros) in it. In general, Java's biggest strength (i.e. the reason people use it despite the shortcomings of the language per se) is its libraries and tool support, which is probably the least important attribute for a beginner language. In fact, while useful in the real world these may negatives from a pedagogical perspective as they can discourage learning to write code from scratch.

  • Java word scramble game [closed]

    - by Dan
    I'm working on code for a word scramble game in Java. I know the code itself is full of bugs right now, but my main focus is getting a vector of strings broken into two separate vectors containing hints and words. The text file that the strings are taken from has a colon separating them. So here is what I have so far. public WordApp() { inputRow = new TextInputBox(); inputRow.setLocation(200,100); phrases = new Vector <String>(FileUtilities.getStrings()); v_hints = new Vector<String>(); v_words = new Vector<String>(); textBox = new TextBox(200,100); textBox.setLocation(200,200); textBox.setText(scrambled + "\n\n Time Left: \t" + seconds/10 + "\n Score: \t" + score); hintBox = new TextBox(200,200); hintBox.setLocation(300,400); hintBox.hide(); Iterator <String> categorize = phrases.iterator(); while(categorize.hasNext()) { int index = phrases.indexOf(":"); String element = categorize.next(); v_words.add(element.substring(0,index)); v_hints.add(element.substring(index +1)); phrases.remove(index); System.out.print(index); } The FileUtilities file was given to us by the pofessor, here it is. import java.util.*; import java.io.*; public class FileUtilities { private static final String FILE_NAME = "javawords.txt"; //------------------ getStrings ------------------------- // // returns a Vector of Strings // Each string is of the form: word:hint // where word contains no spaces. // The words and hints are read from FILE_NAME // // public static Vector<String> getStrings ( ) { Vector<String> words = new Vector<String>(); File file = new File( FILE_NAME ); Scanner scanFile; try { scanFile = new Scanner( file); } catch ( IOException e) { System.err.println( "LineInput Error: " + e.getMessage() ); return null; } while ( scanFile.hasNextLine() ) { // read the word and follow it by a colon String s = scanFile.nextLine().trim().toUpperCase() + ":"; if( s.length()>1 && scanFile.hasNextLine() ) { // append the hint and add to collection s+= scanFile.nextLine().trim(); words.add(s); } } // shuffle Collections.shuffle(words); return words; } }

  • SUN Java and GPL V2 licence issue for linked applications

    - by user255607
    I have recently noticed that the Sun Java code has been released as GPL V2 code (see Google code repo). Does that mean that all applications written in Java and linked to Sun APIs (beans, and so on) are also in GPL ? If we strictly follow the GPL then this should be the case (Libs should be in LGPL, not GPL if we want to build proprietary software on top of it). Is there another commercial licence which can avoid such an issue ? I cannot believe this is the case. There must be an explanation on this. Regards, Apple92

  • Run Java application as a different user [on hold]

    - by Harihar Das
    I need to run a few perl scripts from a Java GUI application. I am using Runtime API to do that. However, few of the perl scripts need to run under a specific user account to have special credentials to access specialized resources (e.g. Database, Files). I have heard of alleviating user access using UAC. But till now I am not able to find the solution. Please help me on how to run a process under a different user login. Is there anything similar to c# impersonization in Java?

  • How difficult did you find the Java Certification Exam

    - by user22904
    I'm just starting out as a Java programmer and have very minimal experience. I would like to improve my knowledge and study for the Java certification. I realize everyone will have a different answer but for those who have taken the certification and passed it, I'd really appreciate if you could tell me your experiences. Just a couple of lines to let me know if you found it hard, very hard. Also how much time did you spend studying. Sorry that this is not a good question. My native language is not English so it is hard for me to say what I want to ask.

  • Learning Java with a simple project

    - by phodu_insaan
    As i remember the time when i was learning PHP, it was suggested to build a simple blog or a forum after reading the language fundamentals. I was told/read that this would cover everything that I would need to learn about PHP from a beginners book. This advice was out there in a number of places, and after following and working with PHP it seems quite good advice. Now, i am learning Java and reading the book "Thinking in Java" by Bruce Eckel. I wonder if there is any such set of similar, small projects that I could take up, that would cover all the essentials and most of what is covered in the book.

  • Java Swing or Java Qt?

    - by Gili
    Can someone with extensive experience with both Qt and Java Swing please discuss whether you would use Swing or Qt under Java, and why? Secondly, what is the business impact of using Qt? Is it reasonably popular or will I have a hard time finding experienced Qt developers? Are there any other business impacts I should be aware of? UPDATE: I am more interested in the technical and business impacts of Swing vs Qt than the license type/fee since in my case the cost is not a concern.

  • Can I find out if the java program was launched using java or javaw

    - by saugata
    This is related to an earlier question by a different user How to detect that code is running inside eclipse IDE I noticed that eclipse always launches programs with javaw rather than java. (This does not imply a program launched with javaw was launched from eclipse). I can find the arguments passed using RuntimeMXBean RuntimemxBean = ManagementFactory.getRuntimeMXBean(); List<String> lst=RuntimemxBean.getInputArguments(); for(int i=0;i<lst.size();i++) System.out.println(lst.get(i)); But this does not tell me whether it was launched using java or javaw. Is there any way to find it out? Another related question is why does eclipse use javaw to launch programs?

  • I'm a beginner Java programmer but I want to be useful

    - by user105418
    Programming has always interested me, but after learning some of the basics of Java(I'm talking high school level), I don't really know what to do from there. I want to be able to apply what I learned in some way, whether it be a volunteer project or something, but I probably don't know enough programming. Is it possible for a novice Java programmer to be useful in some way whatsoever. I want to do this because I feel like I could learn more about programming by helping people in theirs, but I'm not sure if I'm even able to this though. Does anyone have any suggestions on how I can contribute to other people's project in some way or how to apply it in some way?

  • Delays in .net app when connecting to oracle db using Oracle.DataAccess

    - by chris
    I have a .net desktop app that connects to an oracle database. At times, there are very noticable delays. I ran a trace on the code, and it was always in the DataReader.Read(). I turned on sql tracing, and found the following, which corresponds to the delays I'm seeing: (2128) [23-MAR-2010 13:00:07:310] nsprecv: reading from transport... (2128) [23-MAR-2010 13:00:07:310] nttrd: entry (2128) [23-MAR-2010 13:00:24:655] nttrd: socket 676 had bytes read=2047 (2128) [23-MAR-2010 13:00:24:655] nttrd: exit (2128) [23-MAR-2010 13:00:24:655] nsprecv: 2047 bytes from transport There's about a 14 second pause in there. I'm pretty sure that there's not a problem in the code, but not sure where to look at next. Is there anyone out there with experience with oracle trace that can explain what's going on?

  • How to make game menu Java

    - by Deathsbreed
    I've been searching all over for how to make a game menu, but I haven't found anything useful. I have a very simple Pong like game (source-code here), and I want to add a main menu to it. This wouldn't be too much of a problem if I was making a standalone with JFrame instead of an Applet, but I want this to be available on the web (not downloaded). I might have been able to do some of it myself, except for the fact that it would mean having a very heavy main class (in this case the GNP.java file). So I was thinking, is there a way to basically have a Java Applet and have it use a JFrame and how? and if not, what could I do? Thanks!

  • Java on Ubuntu server 12.04?

    - by Sean Dunwoody
    I'm a little confused at the moment. My back story in short, is that I'm trying to set up a Minecraft server on an Ubuntu server I've recently set up, obviously to do this I needed Java, but after googling for a short while I wasn't entirely sure whether it is possible (or legal?) to do so in Ubuntu 12.04 due to licensing type issues - so I installed open JDK instead which appears not to work properly with the Minecraft server software (I half expected this) I'm now considering uninstalling open JDK and instead trying to get proper Java on there instead, my question is, is this possible? Is it Legal? And if so how do I go about doing it? Because I'm finding it very difficult to find any instructions on how to do so for 12.04 . . .

  • How to structure my java packages

    - by MightyPork
    I have a Java library, quite a huge one. I'm asking regarding Best Practices of structuring the source. For example, the logging sybsystem: Option 1: All in one package, named to sort nicely Log - static accessor LogMonitor - interface for log minotor LogMonitorBase - abstract class LogMonitorStdout - print log to console LogWriter - interface for file logger LogWriterSimple - log writer with just one log file LogWriterArchiving - log writer that handles old log files Option 2: Subpackages for Monitors and Writers, with better names Log monitors/LogMonitor monitors/BaseMonitor monitors/StdoutMonitor writers/LogWriter writers/SimpleLog writers/ArchivingLog The second maybe looks better, but perhaps it's not so practical from the java point of view (two extra packages). What do you suggest as the best practice here? A lot in one package, grouped by naming prefixes, or a lot of subpackages with better names?

  • Java Grade Calculator program for class kepp geting the error "Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException." [migrated]

    - by user2880621
    this is my first question I've posted. I've used this site to look at other questions to help with similar problems I've had. After some cursory looking I couldn't find quite the answer I was looking for so I decided to finally succumb and create an account. I am fairly new to java, only a few weeks into my first class. Anyway, my project is to create a program which takes any amount of students and their grades, and then assign them a letter grade. The catch is, however, that it is on a sort of curve and the other grades' letter are dependent on the the highest. Anything equal to or 10 points below the best grade is an a, anything 11-20 points below is a b, and so on. I am to use an array, but I get this error when ran "Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException." I will go ahead and post my code down below. Thanks for any advice you may be able to give. package grade.calculator; import java.util.Scanner; /** * * @author nichol57 */ public class GradeCalculator { /** * @param args the command line arguments */ public static void main(String[] args) { Scanner input = new Scanner(System.in); System.out.println("Enter the number of students"); int number = input.nextInt(); double[]grades = new double [number]; for (int J = number; J >=0; J--) { System.out.println("Enter the students' grades"); grades[J] = input.nextDouble(); } double best = grades[0]; for (int J = 1; J < number; J++) { if (grades[J] >= best){ best = grades[J]; } } for (int J = 0;J < number; J++){ if (grades[J] >= best - 10){ System.out.println("Student " + J + " score is " + grades[J] + " and grade is " + "A"); } else if (grades[J] >= best - 20){ System.out.println("Student " + J + " score is " + grades[J] + " and grade is " + "B"); } else if (grades[J] >= best - 30) { System.out.println("Student " + J + " score is " + grades[J] + " and grade is " + "C"); } else if (grades[J] >= best - 40) { System.out.println("Student " + J + " score is " + grades[J] + " and grade is " + "D"); } else { System.out.println("Student " + J + " score is " + grades[J] + " and grade is " + "F"); } } // end for loop for output }// end main method }
