找不到符號WindowAdapter雖然導入

Question

我正在弄一個小小的JFrame，但它不會找到WindowAdapter，所以我輸入它。

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

你拼寫WindowAdapter()爲WindowAdatper()
