I´ve been searching for it and I found Encog and Neuroph but I don´t know if any about them... I've to do a final project and I need a litle feedback from humans, sometimes google is not enough XD
I have one Map that contains some names and numbers
Map<String,Integer> abc = new TreeMap<String,Integer>();
It works fine. I can put some values in it but when I call it in different class it gives me wrong order. For example:
I putted
abc.put("a",1);
abc.put("b",5);
abc.put("c",3);
some time it returns the order (b,a,c) and some time (a,c,b).
What is wrong with it? Is there any step that I am missing when I call this map?
Hi Experts,
I want to write "Arabic" in the message resource bundle (properties) file but when I try to save it I get this error:
"Save couldn't be completed
Some characters cannot be mapped using "ISO-85591-1" character encoding. Either change encoding or remove the character ..."
Can anyone guide please?
I want to write:
global.username = ??? ????????
How should I write the Arabic of "username" in properties file? So, that internationalization works..

I need to do a search in a map of maps and return the keys this element belong.
I think this implementation is very slow, can you help me to optimize it?.
I need to use TreeSet and I can't use contains because they use compareTo, and equals/compareTo pair are implemented in an incompatible way and I can't change that.
(sorry my bad english)
Map m = new TreeSet();
public String getKeys(Element element) {
for(Entry e : m.entrySet()) {
mapSubKey = e.getValue();
for(Entry e2 : mapSubKey.entrySet()) {
setElements = e2.getValue();
for(Element elem : setElements)
if(elem.equals(element)) return "Key: " + e.getKey() + " SubKey: " + e2.getKey();
}
}
}

what tools to use to write such a web application that will run on Tomcat?
What framework allows to do that in the most straightforward, easy-to-manage and elegant way?
I need to setup LookAndFeel Files in JDK 1.6.
I have two files:
napkinlaf-swingset2.jar
napkinlaf.jar
How can I set this up and use it?
I would like a GTK look and feel OR Qt look and feel, Are they available?
Is it a good practice to set stream references to null after closing them? Would this release resources in any way?
Example:
BufferedReader input= new BufferedReader(new FileReader("myfile.txt"));
// code
input.close();
input = null;
// possible more code
I understand from the official documentation on unowned relationships that the app must use sets of Key objects on either side of the relationship. This makes perfect sense.
Coming from many years of RDBM-style programming, though, I'm pretty confused about how I can model properties of that relationship itself. For example, if I have entities Category and Entry in my many-to-many relationship and would like to persist a dateAdded property, or some other data that are only relevant when both sides of the relationship are known.
I suppose it would be possible to create a third class : CategoryEntry that links the two, but this seems like a kludge.
What is the proposed way to model this kind of situation ?
I'm using the Windows XP look and feel. On a panel containing a button there is a rectangular area around a button that looks like the area that a classic button would take up. That area is not adhering to the color of my panel. For example I'm setting my panel to blue but the area around the button is still white. What is the name of that area. I've tried button.shadow but that's not it.
Thanks

Is a variable inside the main, a public variable?
public static void main(String[] args) {
.........
for(int i=0;i<threads.length;i++)
try {
threads[i].join();
} catch (InterruptedException e) {
e.printStackTrace();
}
long time=0;
....
}
i and time are they both public variables?
Of course if my reasoning is correct, also any variable belonging to a public method should be considered public.. am i right?
Thanks
Good Morning - it is school assignment, I am not asking for any source code (if you can provide any pesudo code it would be awesome).
Here is the problem :(
I have to create a term frequency table. It is not pure TF, I just need to count the words and write down.
I know basic steps to do it
1 - extract all terms (I can do it with file reader)
2 - remove repeating terms (I can do it with TreeMap)
The output of 2nd step would be
Niga, ponga, dinga, bitlo, etc.
3 - Now I have to see if there is any word in current file from above terms or not, if yes then I will count.
Now this is my problem, I stucked on step 3 :(
I have some idea how to count words with TreeMap (treemap.containskey etc.) but it would be global count not local count for each file :(
Any pseudo code?
Hello,

Because I wanna post a new entry in a specified calendar and I need this url.
Thanks!
Writing generated PDF (ByteArrayOutputStream) in a Servlet to PrintWriter.
I am desperately looking for a way to write a generated PDF file to the response PrintWriter.
Since a Filter up the hierarchy chain has already called response.getWriter() I can't get response.getOutputStream().
I do have a ByteArrayOutputStream where I generated the PDF into. Now all I need is a way to output the content of this ByteArrayOutputStream to the PrintWriter. If anyone could give me a helping hand would be very much appreciated!
I'm having some trouble with a hw assignment. In one assignment, we had to create a Person class. Mine was:
public class Person
{
String firstName;
String lastName;
String telephone;
String email;
public Person()
{
firstName = "";
lastName = "";
telephone = "";
email = "";
}
public Person(String firstName)
{
this.firstName = firstName;
}
public Person(String firstName, String lastName, String telephone, String email)
{
this.firstName = firstName;
this.lastName = lastName;
this.telephone = telephone;
this.email = email;
}
public String getFirstName()
{
return firstName;
}
public void setFirstName(String firstName)
{
this.firstName = firstName;
}
public String getLastName()
{
return lastName;
}
public void setLastName(String lastName)
{
this.lastName = lastName;
}
public String getTelephone()
{
return telephone;
}
public void setTelephone(String telephone)
{
this.telephone = telephone;
}
public String getEmail()
{
return email;
}
public void setEmail(String email)
{
this.email = email;
}
public boolean equals(Object otherObject)
{
// a quick test to see if the objects are identical
if (this == otherObject) {
return true;
}
// must return false if the explicit parameter is null
if (otherObject == null) {
return false;
}
if (!(otherObject instanceof Person)) {
return false;
}
Person other = (Person) otherObject;
return firstName.equals(other.firstName) && lastName.equals(other.lastName) &&
telephone.equals(other.telephone) && email.equals(other.email);
}
public int hashCode()
{
return 7 * firstName.hashCode() +
11 * lastName.hashCode() +
13 * telephone.hashCode() +
15 * email.hashCode();
}
public String toString()
{
return getClass().getName() + "[firstName = " + firstName + '\n'
+ "lastName = " + lastName + '\n'
+ "telephone = " + telephone + '\n'
+ "email = " + email + "]";
}
}
Now we have to extend that class and use that class in our constructor. The function protoype is:
public CarLoan(Person client, double vehiclePrice, double downPayment, double salesTax,
double interestRate, CAR_LOAN_TERMS length)
I'm confused on how I use the Person constructor from the superclass. I cannot necessarily do
super(client);
in my constructor which is what the book did with some primitive types in their example. Not sure what the correct thing to do is... Any thoughts? Thanks!
I saw a lot of post on StackOverflow relating to this, but unable to solve my problem.
I want to open a new Panel by clicking a button.
Here is how i try to do it
parameterButton = new JButton("Parametres");
parameterButton.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent e){
createParameterPanel = new DisplayParameterPanel();
createParameterPanel.setVisible(true);
add(createParameterPanel);
};
});
add(parameterButton);
When I click the parameterButton it doesn't open.
How can I open a new panel.
Thanks,
I am trying to write a recursive method to print n number of asteriks in a line and create a new line at the end.
So, TriangleOps.line(5);
would print
*****
This is the code I wrote:
public static void line (int n){
if(n>0){
System.out.println("*");
line(n-1);
}}
instead it prints
*
*
*
*
*
with a lot of space at the end. Can anyone tell me how to remove the line breaks?
J2EE has ServletRequest.getParameterValues().
On non-EE platforms, URL.getQuery() simply returns a string.
What's the normal way to properly parse the query string in a URL when not on J2EE?
Hi, I have some classes and I'm trying to fill the objects of this class. Here is what i've tried. (Question is at the below)
public class Team
{
private String clubName;
private String preName;
private ArrayList<String> branches;
public Team(String clubName, String preName)
{
this.clubName = clubName;
this.preName = preName;

The problem is one of my class elements. I have an arraylist as an element of a class.
When i enter:
AAA as preName
BBB as clubName
c
d
e as Branches
Then as a second element
www as preName
GGG as clubName
a
b as branches
The result is coming like:
AAA BBB c,d,e,a,b
GGG www c,d,e,a,b
Which means ArrayList part of the class is putting it on and on. I tried to use clear() method but caused problems. Any ideas.
Hi,
I have two events for two seperate components, but there is a problem. JTabbedPane's stateChanged event is fired before JFormattedField's focusLost event. Is there a way of making stateChange event to be fired after focusLost event.
Thanks,

I can compile above method. Is there any explanation about the allowed multiple "+" operator?
