每个程序中只有一个public类，主类？

 import java.io.*;

 public class GameSaverTest {
     public static void main(String[] args){
         //创建人物
         GameCharacter one=new GameCharacter(50,"Elf",new String[] {"bow","sword","dust"});
         GameCharacter two=new GameCharacter(200,"Troll",new String[] {"bare hands","big ax"});
         GameCharacter three=new GameCharacter(120,"Magician",new String[] {"spells","invisibility"});

         try{
             ObjectOutputStream os=new ObjectOutputStream(new FileOutputStream("Game.ser"));
             os.writeObject(one);
             os.writeObject(two);
             os.writeObject(three);
             os.close();
         }catch(IOException ex){ex.printStackTrace();}
         one=null;
         two=null;
         three=null;

         try{
             ObjectInputStream is=new ObjectInputStream(new FileInputStream("Game.ser"));
             GameCharacter oneRestore=(GameCharacter) is.readObject();
             GameCharacter twoRestore=(GameCharacter) is.readObject();
             GameCharacter threeRestore=(GameCharacter) is.readObject();

             System.out.println("One's type:"+oneRestore.getType());
             System.out.println("Two's type:"+oneRestore.getType());
             System.out.println("Three's type:"+oneRestore.getType());
         }catch(Exception ex){
             ex.printStackTrace();
         }
     }

 }

程序2：

 import java.io.*;

 public class GameCharacter implements Serializable{
     int power;
     String type;
     String[] weapons;

     public GameCharacter(int p,String t,String[] w){
         power=p;
         type=t;
         weapons=w;
     }

     public int getPower(){
         return power;
     }
     public String getType(){
         return type;
     }
     public String getWeapons(){
         String weaponList="";

         for(int i=0;i<weapons.length;i++){
             weaponList+=weapons[i]+" ";
         }
         return weaponList;
     }
 }
