Here is an example that helps us for setting the close button operation for the frame in java.

Setting the close button operation for the frame in Java



In this section, you will learn how to implement the close button of any frame or window in java application. By default the close button of the frame is not in working state. If you click on the close button of the frame or window that will be cancelled automatically. The close button of the frame has to be set for the desired operation (i.e. closing the frame).

Here, you will see how to set the close button functionality to close the frame or window. This is done using the addWindowListener() method of the Frame class which passes the new instance of the WindowAdapter class that uses the windowClosing() method for receiving the WindowEvent and close the frame or window.

addWindowListener() :
This is the addWindowListener() method which adds the window listener to receive the window event from the window. This method passes the window listener.

WindowAdapter() : 
This is the constructor of the WindowAdapter class of the java.awt.event.*; package. This is an abstract class used for receiving window events.

windowClosing() :
This is the windowClosing() method of the WindowAdapter class invoked when the frame is attempted to close from the window's system menu or close button. This method receives the WindowEvent object.

Here is the code of the program : 

import java.awt.*;
import java.awt.event.*;

public class AwtCloseButtonEvent{
  public static void main(String[] args){
  Frame frame = new Frame("Close Operation Frame");
  Label lbl = new Label("Welcom in Tutorial",Label.CENTER);
  frame.addWindowListener(new WindowAdapter(){
  public void windowClosing(WindowEvent we){
