我是新手@Java編程。我一直在爲SaveFile工作,爲我的遊戲。加載並保存數據。我有2個以下錯誤:Java SaveFile將不起作用

java.io.EOFException 
at java.io.ObjectInputStream$BlockDataInputStream.peekByte(Unknown Source) 
at java.io.ObjectInputStream.readObject0(Unknown Source) 
at java.io.ObjectInputStream.readObject(Unknown Source) 
at Clicker.LoadFile.<init>(LoadFile.java:17) 
at Clicker.mainClass.main(mainClass.java:21) 


java.lang.NullPointerException 
    at Clicker.SaveFile.<init>(SaveFile.java:17) 
    at Clicker.mainClass$1.run(mainClass.java:26) 
    at java.lang.Thread.run(Unknown Source) 

我有MainClass,在那裏我把SaveClass和loadClass的:

package Clicker; 

進口javax.swing.JFrame中;

公共類mainClass {

public static void main(String[] args) { 

    ClickerGame game = new ClickerGame(); 

     JFrame frame = new JFrame("CarCollectionarV1"); 
     frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 

     game.addComponentToPane(frame.getContentPane()); 

     frame.pack(); 
     frame.setVisible(true); 
     frame.setResizable(true); 
     frame.setSize(1000, 700); 

     LoadFile load = new LoadFile(); 

Runtime.getRuntime().addShutdownHook(new Thread(new Runnable() { 

     public void run() { 
     SaveFile save = new SaveFile(); 
     } 
    })); 
} 

完全 「SaveClass」 代碼:

package Clicker; 

import java.io.*; 

public class SaveFile{ 

    ClickerGame CG = new ClickerGame();{ 

try{ 
    File SaveFile = new File("SaveFile.sav"); 
    if(!SaveFile.exists()) { 
     SaveFile.createNewFile(); 
    } 
    FileOutputStream saveFileSub = new FileOutputStream(SaveFile); 
    ObjectOutputStream save = new ObjectOutputStream(saveFileSub); 

    save.writeObject(CG.CarMain.Money); 
    save.writeObject(CG.CarMain.MoneyClicks); 
    save.writeObject(CG.CarMain.Boxes); 
    save.writeObject(CG.CarMain.BoxesClicks); 
    save.writeObject(CG.CarMain.PlayerLevel); 
    save.writeObject(CG.CarMain.BoxLevel); 

save.close(); 
    } 
    catch(Exception exc){ 
    exc.printStackTrace(); 
    } 
    } 
} 

,充滿 「loadClass的」 代碼:

package Clicker; 

import java.io.*; 

public class LoadFile { 

    ClickerGame CG =new ClickerGame();{ 

     try{ 
      File SaveFile = new File("SaveFile.sav"); 
      if(!SaveFile.exists()) { 
       SaveFile.createNewFile(); 
      } 
      FileInputStream SaveFileSub = new FileInputStream(SaveFile); 
      ObjectInputStream load = new ObjectInputStream(SaveFileSub); 

      CG.CarMain.Money = (int) load.readObject(); 
      CG.CarMain.MoneyClicks = (int) load.readObject(); 
      CG.CarMain.Boxes = (int) load.readObject(); 
      CG.CarMain.BoxesClicks = (int) load.readObject(); 
      CG.CarMain.PlayerLevel = (int) load.readObject(); 
      CG.CarMain.BoxLevel = (int) load.readObject(); 

      load.close(); 
      } 
      catch(Exception exc){ 
      exc.printStackTrace(); 
      } 
      }

設置您的代碼格式,併爲此網站使用正確的格式。此代碼不可讀,因此相當糟糕。 – bcsb1001

這個文件的'SaveFile.java:17'第17行究竟是什麼? –

也閱讀[Java編碼約定](http://www.oracle.com/technetwork/java/codeconventions-135099.html) –

從我所收集的CG.CarMain.Money ISN」當在SaveFile的環境中調用時導致被定義和文件寫入流產。從那裏你有一個LoadClass試圖讀取,只有提高EOFException損壞的文件。
