虽然导入了找不到符号WindowAdapter

Question

我正在写一个小JFrame，但它不会找到WindowAdapter，虽然我正在导入它。

import java.awt.event.*; //WindowAdapter should be within this...
import javax.swing.*;

public class Test extends JFrame{

    public Test(){
        setDefaultCloseOperation(JFrame.DO_NOTHING_ON_CLOSE);
        addWindowListener(new WindowAdatper() {
            public void windowClosing(WindowEvent e) {
                System.out.println("EXIT!!!!");
            }
        });
    }

    public static void main(String args[]){
        new Test();
    }
}

Answer 1

您将WindowAdapter()拼写为WindowAdatper()
