//This is the problem hlp me pls the problem is Error: Main method is not static //in class ilkframe.ilkframe, please define the main method as:
 //  public static void main(String[] args)
//help me pls as fast as you can ?

Answer 1

You have badly defined your mains methods that are correctly place in both classes :

public void main(String[] args) {

And the JVM told you to :

Main method is not static in class ilkframe.ilkframe, please define the main method as: 
    public static void main(String[] args)

Also, you have defined a main method outside of the class

...
import java.awt.event.MouseEvent; 

public static void main(String[] args) {
class ilkframe extends JFrame {

This should not compile at all. Remove that declaration... a method need to be in a class

FYI: this is not an Eclipse error, I would expect a compile error and after that a runtime error. But all from Java, not eclipse.
