GUI based program
import javax.swing.*;
import java.awt.event.*;
import javax.swing.event.*;
class GUI2 extends JFrame implements ActionListener
{
public static void main(String s[])
{
JFrame jf=new JFrame("my tool");
JButton jb=new JButton("submit");
jb.addActionListener(this);
jf.add(jb);
}
public void ActionPerformed(ActionEvent ae)
{
System.out.println("button clicked");
}
}
this is showing error :
GUI2 is not abstract and doesnot override abstract method ActionPerformed(Action Event)in ActionListener

ActionPerformed != actionPerformed. Case matters.

Re: GUI based program
thanks. but its now showing one error :
non-static variable this cannot be referenced from a static context
jb.addActionListener(this);
Re: GUI based program
You're in the main() method, which is static. That means you aren't "inside" a particular instance of GUI2, so you can't use the this keyword. You need to instantiate an instance of GUI2 before you can use it.
