少一个事件监听接口
public class app16_10 implements ActionListen

解决方案 »

  1.   

    少一个事件监听接口
    public class app16_10 implements ActionListener
      

  2.   

    btn.addMouseListener少了ActionListener
      

  3.   

    F:\java\16\app16_10.java:17: <anonymous app16_10$1> is not abstract and does not override abstract method mouseReleased(java.awt.event.MouseEvent) in java.awt.event.MouseListener
    btn.addMouseListener(new MouseListener(){public void mouseClicked(MouseEvent e){
                                                                         ^
    就是这个错误
      

  4.   

    鼠标监听器接口的方法实现不全，下面几个都没实现。MouseListener.mouseEntered(MouseEvent)
    MouseListener.mouseExited(MouseEvent)
    MouseListener.mousePressed(MouseEvent)
    MouseListener.mouseReleased(MouseEvent)
