Using GridLayout as GUI

[Koert Kopbeen]

Hey everyone

I sent in a previous post (Creating GUI for BattleShips) and I tweaked my program. it's basically perfect without the GridLayout (which I found and would work PERFECTLY if I knew how to use it. I imported it, but I really don't know what to do. Anyone wanna help me out? As I said previously, the GUI can be VERY simple, it's the idea that counts.

Come on, guys, PLEASE help me!

The code follows! Please guys ASAP!!

  import java.io.*;
import java.awt.GridLayout;
 
public class BattleShips
{
 
    private char[] [] board = new char [10] [10];

    void blank ()
    {
 

        for (int i = 0 ; i < 10 ; i++)

            for (int j = 0 ; j < 10 ; j++)

Shouldn't GUI questions go to the Swing/etc... GUI forum?

[marc weber]

How far have you gotten with the Swing Tutorial?

Can you write a program that just displays a 10x10 grid (with a JButton in each position)?

Yep. Off we go.

[Michael Dunn]

you've cross-posting here, javaworld (and everywhere else I suppose), multiple
times, begging everyone to write the program for you.

If you had, instead, spent the time reading the links provided, you would have
finished the project by now (it really is that simple), and you would have
learned a 'bucketload' - to carry forward to your next gui project.

so, get into the links provided, head down, 'A' up, and just do it.

help for specific questions about specific problems is readily available.

good luck.
