Answer 1

넣을 때 :

public class Profile extends JFrame implements ActionListener, MouseLIstener{ 

당신은 잘못의 MouseListener의 이름을 입력 등의 MouseListener을.

변경

MouseLIstener 

다음

MouseListener 

및 아래 unimplement 방법을 추가, 당신의 프로그램에 대한 작동합니다.

public void mouseClicked(MouseEvent e) { 
     // TODO Auto-generated method stub 

    } 


    public void mouseEntered(MouseEvent e) { 
     // TODO Auto-generated method stub 

    } 


    public void mouseExited(MouseEvent e) { 
     // TODO Auto-generated method stub 

    } 


    public void mousePressed(MouseEvent e) { 
     // TODO Auto-generated method stub 

    } 


    public void mouseReleased(MouseEvent e) { 
     // TODO Auto-generated method stub 

    }
