Double-Click.

You should read swing tutorials about listeners first.

This is done very easy.

list.addMouseListener(new MouseAdapter() {

@Override

public void mouseClicked(MouseEvent e) {

if (e.getClickCount() == 2) {

//your code

}

}

});

I think this might help you!!

System print out when you double click some item.

import java.awt.*;

import java.awt.event.*;

import javax.swing.*;

import javax.swing.event.*;

import java.awt.*;

public class AsciiChar_Listing {

String[] data = { "zero", "one", "two", "three", "four", "five" };

JList list = new JList(data);

public AsciiChar_Listing() {

Action displayAction = new AbstractAction() {

public void actionPerformed(ActionEvent e)

{

JList list = (JList)e.getSource();

System.out.println(list.getSelectedValue());

}

};

this.addAction(list, displayAction);

}

private static final KeyStroke ENTER = KeyStroke.getKeyStroke(KeyEvent.VK_ENTER, 0);

static void addAction(JList source, Action action) {

InputMap im = source.getInputMap();

im.put(ENTER, ENTER);

source.getActionMap().put(ENTER, action);

source.addMouseListener( new ActionMouseListener() );

}

static class ActionMouseListener extends MouseAdapter {

public void mouseClicked(MouseEvent e) {

if (e.getClickCount() == 2) {

JList list = (JList)e.getSource();

Action action = list.getActionMap().get(ENTER);

if (action != null) {

ActionEvent event = new ActionEvent(list,ActionEvent.ACTION_PERFORMED,"");

action.actionPerformed(event);

}

}

}

}

public static void main(String[] args) {

try {

UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());

} catch (Exception e) { }

JFrame frame = new JFrame();

frame.setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE );

frame.getContentPane().add( new JScrollPane(new AsciiChar_Listing().list) );

frame.setSize(200, 300);

frame.setLocationRelativeTo( null );

frame.setVisible( true );

}

}
