In this example we are going to see how to create a JList component in a Java Desktop Application. The JList component provides a very easy way to get user input, especially when you want to give the user a number of specific options.
In order to get the selected value from a JList, one should follow these steps:
- Create a class that extends
JFrame. - Create an array of objects. These will be the values of the
JList. - Create a new
JListwith the above array.
Let’s see the code:
package com.javacodegeeks.snippets.desktop;
import java.awt.FlowLayout;
import javax.swing.JFrame;
import javax.swing.JList;
public class CreateJListExample extends JFrame {
private static final long serialVersionUID = 1L;
public CreateJListExample() {
// set flow layout for the frame
this.getContentPane().setLayout(new FlowLayout());
Object[] data = { "Value 1", "Value 2", "Value 3", "Value 4", "Value 5" };
JList list = new JList(data);
// add list to frame
add(list);
}
private static void createAndShowGUI() {
//Create and set up the window.
JFrame frame = new CreateJListExample();
//Display the window.
frame.pack();
frame.setVisible(true);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}
public static void main(String[] args) {
//Schedule a job for the event-dispatching thread:
//creating and showing this application's GUI.
javax.swing.SwingUtilities.invokeLater(new Runnable() {
public void run() {
createAndShowGUI();
}
});
}
}This was an example on how to create a JList in a Java Desktop Application.
