How close the window

Question

I've tried to click the 'X' button in the window but the window frame don't close at all.
here's the code
public class test {
     public static void main(String args[]) {
     Frame frame=new Frame("Red VS Blue");
     frame.setSize(400,200);
     frame.setLayout(new GridLayout(2,0));     
     frame.setVisible(true);
i'll like to know what's going wrong why can't i close the window frame and exit the application.
hope someone can tell me the reason and how to solve it.
thanks in advance

Answer 1

You have now the code.
And the reason is: you have to explicitly register a listener with your frame. And this listener must implement the windowClosing(WindowEvent) method in order to respond to clicking on the 'X' button.
Here you can find some information about the event handling:

And here is another tuttorial about swing and the MVC pattern:
