有人可以解釋爲什麼我得到這個錯誤與計時器？

Question

爲什麼我在計時器中出錯？在代碼下面說明錯誤是什麼。我無法弄清楚什麼即時做錯了....誰能幫我

 import java.util.Timer; 
     import javax.swing.ImageIcon; 
     import javax.swing.JPanel; 

     /** 
     * 
     * @author Rich 
     */ 
    public class Board extends JPanel implements ActionListener{ 
     Dude p; 
     Image img; 
     Timer time; 

     public Board() { 
     p = new Dude(); 
     addKeyListener(new AL()); 
     setFocusable(true); 
      ImageIcon i = new ImageIcon("images.jpg"); 
      img = i.getImage(); 
      time = new Timer(5,this); 
      time.start(); 
     } 

     public void actionPerformed(ActionEvent e) { 
     p.move(); 
     repaint(); 
     } 

基本上錯誤即時得到是

no suitable constructor found for Timer(int,OurGame.Board) 
constructor java.util.Timer.Timer(java.lang.String,boolean) is not applicable 
    (actual argument int cannot be converted to java.lang.String by method invocation conversion) 
constructor java.util.Timer.Timer(java.lang.String) is not applicable 
    (actual and formal argument lists differ in length) 
constructor java.util.Timer.Timer(boolean) is not applicable 
    (actual and formal argument lists differ in length) 
constructor java.util.Timer.Timer() is not applicable 
    (actual and formal argument lists differ in length) 

Answer 1

您應該導入javax.swing.Timer而不是java.util.Timer。

Answer 2

在以下行「這個」變量：

time = new Timer(5,this); 

指的是當前類，而定時器類不知道該如何處理;）

Answer 3

您已輸入java.util.Timer。使用javax.swing.Timer。 不是你的錯，你會看到很多。
