Hi, looking at your code, I can see only 0 as answer

When you do 5/9, your dealing with ints, so thats 0.

I think you should do 5.0/9 or 5/9.0 or (double)5/9 or 5/(double)9, or or just...

Hi, I haven't tried it yet, I've been trying a new hard drive that I have. So far the same occurence has not happened, and hopefully won't (touch wood).

Hi, I'm hoping someone can help me with this problem.

Over last couple of days, when I start up computer, it gets to the windows screen, and the blue bar thing just goes round and round, and it...

I don't get it, its pretty pointless, but does show how to draw things.

I'm building a 3D chessboard which should be useful, but its too big to fit as a code snippet.

Whats the problem?

It should work fine

lol, quite witty!

A couple of ideas..

A chess game (Will take a long time, I've done one)
A checkers game, similar to chess, but easier
Connect 4

Build a 3D rubiks cube
Or build a program where you can view...

Code is too big to post, I think I've fixed it, I just use requestFocus() on the JMenuBar, after removing the JInternalFrame.

Hi, I have an application, that has a JFrame.
Added to the JFrame's contentPane is a JDesktopPane.

I use JMenuItems in the JMenu (in JMenuBar) to add, and then remove a JInternalFrame inside the...

Seems like a simply program, why would it take so long?

Theres only 8!=40,320 positions to look at then test.

If you put a queen in each column, then first queen has 8 options, next has 7, and...

Hi

I'm writing a chess program,

So I might be able to help a little, you would obviously need alpha-beta pruning.
I guess you would use iterative deepening...

Its simple, I don't see the point for all that code, and I'm not sure why your class is called LinkedList, theres already a LinkedList in the java.util package.
I've just written the code below,...

Nice program, but not very fun.
If you could make some mad coloured images that would be more fun.
Still good though, does what it says on the tin!

You can do either, but initialising a 3D array in one go can be a little daunting, depending on what your putting in.

You could just initialise all your double arrays, then do...
String[][][]...

Thanks, I asked in javaranch too, they said the same thing.
Seems a bit unusual to do this though, I was trying everything to get it to work, then I printed out some data from 'conn' and it worked....

Ok, it works, but this is bonkers, if I miss out the line...
conn.getContentType();

Then it wont work, but it always works with it.

I've added the class below, if anyone wants to try it,...

Ok, I got it to work!

Thanks very much!

I'll have a look at the code shortly.
Its nice to get some good comments instead of vague comments that dont help.

Thanks

I don't want to use signed applets, they are annoying.
I know I can use php, but doesn't seem theres any code on the internet to show this except for scraps of random bits of code which doesn't help.

Hi, I'm looking to update a MySql database from an applet.
The 2 roots I was thinking were:
Applet->php->database
Applet->servlet->database

But my webhost doesn't allow servlets/jsp, so I would...

Yeh, currently I'm adding the jmf.jar to the build path, but its not really adding it, its just adding the path of the jar file.

I'm trying to make the project portable, so users can just...

This program generates the 6 faces of a colour cube.
The faces are displayed in a JPanel, and they are also saved to C:/Faces as PNG files.
So non-windows users might have to alter code slightly.

Interesting, but not very fun.
But nicely constructed, and a good tool for beginners to look at to get a flavour of guis.

I don't get it, are you using normal dice with 1-6 on?

I haven't read the code, but perhaps something like this...
You have an array of length 6 eg dice[].
Each time you get a 1, you do dice[0]++;
Each time you get a 2, you do dice[1]++;

In...

Hi, I'm building an application and I want to it to play mp3 files.
I have it working, basically by installing JMF2.1.1e, and then I add its jmf.jar file to the build path of the project within...

Yes, you are correct, I did do a CLR project.

I just tried..

#include <iostream>
using namespace std;
int main()
{
cout << "Hello, World!\n";
}

Hi, I just downlaoded Visual C++, the
Microsoft Visual C++ 2005 Express Edition.

Its not the same as C, I opened a command prompt project, and I have to use...

Hello there, I come from a Java background, and I am a very able with java.
I would like to try C++ to build a chess engine, since my java chess engine lacks the performance that can be obtained...

I doubt its impossible, the information is on the OS, I think its possible, if it wasnt, why have an assignment on it.

Another point to note...
If you do not call super(...) in your constructor, then it is called automatically for you on the default no-args constructor of the super class.

So supposing in super...

Ok, this is easy...

If you dont have any constructors in your class, then you automatically get the default one for free...
Book()

You have a constructor..Book(a,b,c)
So therefore, you do...

Hmmm, I don't get it

In your Book2 class, you've got:

super(bookTitle, itemNumber, bookUnits, bookPrice);

but when I look at java.awt.print.Book,
the only constructor I see is Book().
...

Question is a little vague, but I think you mean:

int x=5;
String y=""+x;

So y is "5"

To reverse this, you could grab the character...

int x=y.charAt(0);

I think your parameters for ArrayList.add(..)
are back to front.
The index comes first.
I've never really used ArrayList to be honest, I like LinkedList, but they are pretty similar.

So you...

If you use an IDE like eclipse, you can JAR it there, by right clicking on project, then 'Export'

If you want to convert into an exe file, its probably easiest to use a tool like......

Your question is a little vague,
I guess you want a button to generate then open a JFrame.
I can't answer your question specifically, but perhaps the following will help.

Thanks I see it.

Now I need a database to try with it.
If you have one, could you email it to me?

Or point me to where I can find one.

Thanks
