package ioStream;
import java.io.*;
public class ChangeTest {

	public static void main(String[] args) throws FileNotFoundException, IOException, ClassNotFoundException {
		ObjectOutputStream oos=new ObjectOutputStream(new FileOutputStream("person.txt"));
		ObjectInputStream ois=new ObjectInputStream(new FileInputStream("person.txt"));
		Person p1=new Person(18,"Turing");
		Person p2=new Person(18,"Zhao Yan");
		oos.writeObject(p1);
		oos.writeObject(p2);
		oos.flush();
		Person p11=(Person)ois.readObject();
		Person p22=(Person)ois.readObject();
		System.out.println(p11);
		System.out.println(p22);
		oos.close();
		ois.close();
	}

}

class Person implements Serializable{
	int age;
	String name;
	
	public Person(int age, String name) {
		super();
		this.age = age;
		this.name = name;
	}
	public Person() {
		super();
		// TODO Auto-generated constructor stub
	}
	@Override
	public String toString() {
		return "Person [age=" + age + ", name=" + name + "]";
	}
}

输出： 

Person [age=18, name=Turing]
Person [age=18, name=Zhao Yan]
