Java中的非常簡單的Hang子手程序

Question

我想用一個GUI來製作一個非常簡單的hang子手程序，該程序使用6個圖像來顯示遊戲的進程。我想對單詞「Hello」進行硬編碼，並且每次用戶都會使圖像發生變化。 （總共6張連續圖像）。

我已經設法使用Netbeans上的Swing庫來製作GUI，但是我很難理解如何繼續使用實際的代碼。 任何指針？

import javax.swing.JOptionPane; 
import java.util.Scanner; 
import java.util.Random; 
import java.io.*;

所有你需要開始與後臺代碼，不可見部分的第一位。

例如，您可以創建一個名爲Hangman的類，它提供了一種方法來更改進度（添加一個錯誤），併爲您提供當前繪製狀態的圖像。

僞代碼，如：

public class Hangman 
{ 
    private int mistakesDone; 

    private HashMap<Integer, Image> progressImages; 

    public Hangman() 
    { 
     mistakesDone = 0; 
     progressImages = new HashMap<Integer, Image>(); 

     for(int i = 0; i < 7;i++) 
      progressImages.put(i, new ImageIcon(new URL("hangman_" + i)).getImage()); 
    } 

    public Image getCurrentImage() 
    { 
     return proressImages.get(mistakesDone); 
    } 

    public void mistakeDone() 
    { 
     mistakesDone++; 
    } 

    public int getMistakesDone() 
    { 
     return mistakesDone; 
    } 

    public void resetMistakes() 
    { 
     mistakesDone = 0; 
    } 
} 

現在，你有你的劊子手類，你需要在你的主遊戲-Class，以創建它的對象或者無論你叫它。當你想繪畫的時候，你可以讓Object來獲取當前的圖像。記住更新錯誤完成！

我會推薦你​​做同樣的猜測部分的基本代碼！ （Outsourcsing在面向對象的語言中是一件非常好的事情）

祝你好運，如果有些事不明確，請發表評論。
