Answer / raj
By default the close button of the frame is not in working
state.The close button of the frame has to be set for the
desired operation (i.e. closing the frame).
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.
frame.addWindowListener(new WindowAdapter(){
public void windowClosing(WindowEvent we){
System.exit(0);
}
});

Answer / ayyappan raja
use, Static method of JFrame called setDefaultCloseoperation
()and pass the arguments as ONE of follows :
Arguments Description
1.JFrame.EXIT_ON_CLOSE Exits the application.
2. JFrame_HIDE_ON_CLOSE closes the clicked frame
window,not the application.
For example,
class Frame1 extends JFrame{
public Frame1(){
super(" FrameTest ");
setSize(400,340);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setVisible(true);
}
}
