MouseAdapter使用方法

[yanjy2112]

package MouseAdapt;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class MouseAdaptDemo extends JFrame implements MouseListener,MouseMotionListener{

private JLabel JL;
private MouseAdapter hander=new MouseAdapter(){
public void mouseClicked(MouseEvent event)
{
JL.setText("点击坐标是("+event.getX()+","+event.getY()+")");
}
};
public MouseAdaptDemo(){
super("MouseAdapt");
getContentPane().setLayout(new BorderLayout());
getContentPane().add(JL, BorderLayout.SOUTH);
addMouseListener(hander);
setSize(275,100);
setVisible(true);
}
public static void main(String[] args){
MouseAdaptDemo application=new MouseAdaptDemo();
application.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}
}


使用了Mouseadapter但是还是提示MouseAdapterDemo为抽象类，为定义全部函数，请问下这是怎么回事？

你类里定义了MouseAdapter变量，但是你MouseAdapterDemo类本身没有实现MouseListener,MouseMotionListener接口的方法。 你的代码 public class MouseAdaptDemo extends JFrame implements MouseListener,MouseMotionListener 把implements MouseListener,MouseMotionListener删掉
