java 对象序列化与反序列化

package com.JavaIOMytest;

import java.io.*;

public class Person implements Serializable {/*对象继承自Serializable*/
	private String name;
	private int age;
	public Person(String name,int age) {
		this.name=name;
		this.age=age;
		
	}

		return"姓名："+this.name+",年龄："+this.age;
	}

}

		Person p=(Person)cin.readObject();/*从文件中读入内容，之后将读入 的内容转型为 Person 类的实例*/
		System.out.println(p);/*行直接打印 Person 对象实例，在打印对象 时，默认调用 Person 类中的 toString()方法*/
