Question

所以我有这个代码，每次编译它都会得到错误：MouseEvent不是抽象的，也不会覆盖abtract方法mouseExited。

任何人都可以告诉我为什么或如何解决它。

`

import javax.swing.*;

import javax.swing.border.LineBorder;

import javax.swing.event.MouseInputListener;

import java.awt.*;

import java.awt.event.*;

public class MouseEvent extends JFrame implements MouseInputListener {

JLabel label = new JLabel("Label");
//constructor
public MouseEvent() {
    JPanel panel = new JPanel();
    panel.setLayout(new BorderLayout());
    panel.add(label, BorderLayout.NORTH);
    getContentPane().add(panel);

    setSize(800,400);
    setVisible(true);
}//end constructor

//main method
public static void main(String args[]){
    new MouseEvent();

}//end main method

public void mouseClicked(MouseEvent e){
    label.setText("Mouse Clicked");
}

public void mouseEntered(MouseEvent e){
    label.setText("Mouse Entered");
}
 public void mouseExited(MouseEvent e){
    label.setText("Mouse Entered");
}

public void mousePressed(MouseEvent e){
    label.setText("moyse held");
}

public void mouseReleased(MouseEvent e){
    label.setText("mouse released");
}

public void mouseDragged(MouseEvent e){
    label.setText("Mouse Dragged");
}

public void mouseMoved(MouseEvent e){
    label.setText("mouse moved");
}

} //结束课程

任何帮助将不胜感激。

尝试更改类的名称以避免与java的MouseEvent类冲突。

获取鼠标事件不是抽象错误
