Problem with my code

Posted: Nov 30, 2003 9:37 AM

Hi I have a problem with my code. First let me explain what I am trying to do:

Create 26 buttons each with a letter of the alphabet, then create
swing applet to hold panels in a five by one grid. Each the 1st four
panels have six buttons and the fifth has 2.

Problem.......my grid is 26 panels instead of the five. Here is my code:

import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class Alphabet extends JApplet implements ActionListener
{
JButton button5 = null;
JLabel alphaLabel = null;

public void init()
{
Container con = getContentPane();
con.setLayout(new GridLayout());
JPanel panel = new JPanel(new GridLayout(1,5));
JButton button1 = new JButton("A B C D E F");
JButton button2 = new JButton("G H I J K L");
JButton button3 = new JButton("M N O P Q R");
JButton button4 = new JButton("S T U V W X");
JButton button5 = new JButton("Y Z");
alphaLabel = new JLabel(" ALPHABET LETTER ");
button5 = new JButton("Y Z");
panel.add(button5);
button5.addActionListener(this);
panel.add(button1);
p anel.add(button2);
panel.add(button3);
panel.add(button4);
panel.add(alphaLabel) ;
JButton a = new JButton("A");
JButton b = new JButton("B");
JButton c = new JButton("C");
JButton d = new JButton("D");
JButton e = new JButton("E");
JButton f = new JButton("F");
JButton g = new JButton("G");
JButton h = new JButton("H");
JButton i = new JButton("I");
JButton j = new JButton("J");
JButton k = new JButton("K");
JButton l = new JButton("L");
JButton m = new JButton("M");
JButton n = new JButton("N");
JButton o = new JButton("O");
JButton p = new JButton("P");
JButton q = new JButton("Q");
JButton r = new JButton("R");
JButton s = new JButton("S");
JButton t = new JButton("T");
JButton u = new JButton("U");
JButton v = new JButton("V");
JButton w = new JButton("W");
JButton x = new JButton("X");
JButton y = new JButton("Y");
JButton z = new JButton("Z");
con.add(a);
con.add(b);
con.add(c);
con.add(d);
con.add(e);
con.a dd(f);
con.add(g);
con.add(h);
con.add(i);
con.add(j);
con.add(k);
con.add(l);
c on.add(m);
con.add(n);
con.add(o);
con.add(p);
con.add(q);
con.add(r);
con.add(s );
con.add(t);
con.add(u);
con.add(v);
con.add(w);
con.add(x);
con.add(y);
con.a dd(z);

}

public void actionPerformed(ActionEvent e)
{
Object source = e.getSource();

if (source == button5)
{
alphaLabel.setText("Folder X");

}
}
}

While I do not have the answer, I do have something that can make your life easier. You can increment characters so they go up from A to Z using a for loop, like this:

import java.io.*;

public class MrClean
{
public static void main(String[] args)
{
int lame = 65;//the ASCII value of 'A' is 65. You should note that the value of 'a' is different from 'A'
//if you wish to print the value of a letter, you can with this statement:
//System.out.print("The value of 'A' is: " + (int)'A');
for(lame=0;lame<65+25;++lame){
System.out.print((char)lame);
}
}}
