method not abstract, does not override actionperformed method.

[Theman]

i am completely new to java, so this might be a very basic question.

i am trying to make this applet that a user can define red, blue and green in numbers and then the number displays as the applets background color.

but when i compile it gives this error message


E:\java\ch6\myColor.java:15: myColor is not abstract and does not override abstract method actionPerformed(java.awt.event.ActionEvent) in java.awt.event.ActionListener
public class myColor extends Applet implements ActionListener

The error is very direct. It says your class mycolor is implementing an interface ActionListener. According to the java principles " if a class implements an interface the class has to implement all the methods of the interface ,Or else the class has to be an abstract class.

Confusing ..............

To solve the error in your class add a method inside the color.

Code:

public void actionPerformed(java.awt.event.ActionEvent){
}

But this is a temporary solution. I would suggest you to do 2 things.

1) Read OOps concepts of Java

2)Use some editor for Java like Eclipse. Eclipse blog
