java - "The method addActionListener(ActionListener) in the type AbstractButton is not applicable for the arguments"错误

Question

我想创建一个JFrame它在控制台上打印出来:“它有效!!”当您单击JButton时。下面是代码:

import java.awt.FlowLayout;
import java.awt.event.MouseAdapter;
import java.awt.event.MouseEvent;

import javax.swing.JButton;
import javax.swing.JFrame;

public class CurrentlyMajorCodesCompiler extends JFrame {

public static void main (String args[]) {
CurrentlyMajorCodes CMC = new CurrentlyMajorCodes();

CMC.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}
}

public class CurrentlyMajorCodes extends JFrame {

private JButton ClickSpeedTest;
private tensCPS TCPS;

public CurrentlyMajorCodes () {
    super("Major Code Compiler");
    setLayout(new FlowLayout());

    ClickSpeedTest = new JButton("Click Speed Test");
    add(ClickSpeedTest);

    ClickSpeedTest.addActionListener(new MouseAdapter () {
        public void mouseClicked (MouseEvent event) {
            System.out.println("It works!!");
        }
    });

    setSize(250, 250);
    setVisible(true);
}
}

但是，位于:ClickSpeedTest.addActionListener ，它给了我一个错误:

The method addActionListener(ActionListener) in the type 
    AbstractButton is not applicable for 
    the arguments (new MouseAdapter(){})`

我不明白它想传达什么，因为我从未使用过 AbstractButton在代码中，甚至不知道它是什么。有人可以帮忙吗？

MouseListener 与 ActionListener 不同。您需要使用稍后的内容

ClickSpeedTest.addActionListener(new ActionListener () {
    public void actionPerformed (ActionEvent event) {
        System.out.println("It works!!");
    }
});
