jButton array !!

Try something like this:

import java.awt.*;

import java.awt.event.ActionEvent;

import java.awt.event.ActionListener;

import javax.swing.*;

class ButtonTester extends JFrame

{

int buttonX = 20;

int buttonY = 20;

int buttonWidth = 60;

int buttonHeight = 60;

int borderSize = 6;

int btnCount = 60;

int btnColumns = 10;

ButtonTester()

{

JPanel pane = new JPanel();// panel for buttons

GridLayout gl = new GridLayout(0, btnColumns);

gl.setHgap(borderSize);// gridlayout setup

gl.setVgap(borderSize);// gridlayout

pane.setLayout(gl);

// here's our button array

JButton[] myBtns = new JButton[btnCount];

// create each button in this for loop.

for (int indx = 0; indx < myBtns.length; indx++)

{

myBtns[indx] = new JButton(Integer.toString(indx));

myBtns[indx].setBounds(buttonX, buttonY,

buttonWidth, buttonHeight);

// attach each button to the same actionListener

myBtns[indx].addActionListener(listener);

// add each button to the panel

pane.add(myBtns[indx]);

}

this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

this.setSize(400, 400);

pane.setBorder(BorderFactory.createEmptyBorder(

borderSize, borderSize, borderSize, borderSize));

this.getContentPane().add(pane);

this.pack();

this.setVisible(true);

}

private ActionListener listener = new ActionListener()

{

public void actionPerformed(ActionEvent e)

{

// find out which button was pressed

JButton myBtn = (JButton) e.getSource();

StringBuilder sb = new StringBuilder();

// display which button was pressed

sb.append("You pressed button " + myBtn.getText());

sb.append("\n" + "button size is: ");

sb

.append("(" + String.valueOf(myBtn.getWidth())

+ ", " + String.valueOf(myBtn.getHeight())

+ ")");

sb.append("\n" + "button location is: ");

sb.append("(" + String.valueOf(myBtn.getX()) + ", "

+ String.valueOf(myBtn.getY()) + ")");

JOptionPane.showMessageDialog(null, sb.toString());

}

};

private static void createAndShowGUI()

{

ButtonTester bt = new ButtonTester();

}

public static void main(String[] args)

{

javax.swing.SwingUtilities.invokeLater(new Runnable()

{

public void run()

{

createAndShowGUI();

}

});

}

}

have you got something like that...

...

JButton[] buttonsArray=new JButton[10];

JFrame frame = new JFrame("FrameDemo");

frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

JPanel jp=new JPanel();

for(int i=0;i < buttonsArray.length;i++){

buttonsArray[i]=new JButton("btn: "+i);

jp.add(buttonsArray[i]);

}

frame.getContentPane().add(jp);
