Public class testapp extends JFrame implements ActionListener{}

the error is - "testapp is not abstract & does not override abstract method actionPerformed (java.awt.event_ActionEvents) in java.awt.events_ActionListener"

Answer 1

Classes that implement an interface must implement the methods defined by it. In your case you must implement the actionPerformed method in your class.

Answer 2

You need to implement the methods defined by the interface. Paste:

public void actionPerformed(ActionEvent e)
{
}

into your code.
