关于Java SE出现报错Exception in thread "main" java.lang.Error: Unresolved compilation problems...

自学Java一个月了，今天在学习序列化得时候自己动手写了一个例程，如下：

package com.JoyWork.Seria;

import java.io.*;

public class text01 implements Serializable{

public static void main(String[] args) {

// TODO Auto-generated method stub

GameCharater Elt = new GameCharater(50,"Elf",new String[]{ "bow","sword","dust"});

GameCharater Troll = new GameCharater(200,"Troll",new String[]{"bara hands","big ax"});

try{

FileOutputStream fs = new FileOutputStream("GameCharater.ser");

ObjectOutputStream os = new ObjectOutputStream(fs);

os.writeObject(Elt);

os.writeObject(Troll);

os.close();

} catch(Exception e){e.printStackTrace();}

try{

ObjectInputStream os = new ObjectInputStream(new FileInputStream("GameCharater.ser"));

Object Elf = os.readObject();

Object Trolll = os.readObject();

GameCharater elf = (GameCharater)Elf;

GameCharater troll = (GameCharater)Trolll;

System.out.println(elf.getPower()+" "+elf.getType());

System.out.println(troll.getPower()+" "+troll.getType());

} catch(Exception e){e.printStackTrace();}

}

public class GameCharater implements Serializable{

private int Power;

private String Type;

private String[] weapons;

public GameCharater (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 List = null;

for(int i =0;i<weapons.length;i++){

List += weapons[i]+" ";

}

return List;

}

}

}

结果发现报错：

Exception in thread "main" java.lang.Error: Unresolved compilation problems:

No enclosing instance of type text01 is accessible. Must qualify the allocation with an enclosing instance of type text01 (e.g. x.new A() where x is an instance of text01).

at com.JoyWork.Seria.text01.main(text01.java:8)

即类型text01没有外围实例访问。必须与类型text01的类实例限定分配（例如x.newA（），其中x是text01的一个实例）。

经过查阅资料发现是内部类的问题，因为我写的内部类GameCharater是动态的，也就是开头以public class开头。而主程序是public static class main。在Java中，类中的静态方法不能直接调用动态方法。只有将某个内部类修饰为静态类，然后才能够在静态类中调用该类的成员变量与成员方法。

解决办法有两个：1、不要写内部类，写成单独的一个bean对象 2、将内部类写成public static类型的
