java对象序列化和反序列化

就是对象的写和文件的读操作哦

package xuliehua;

import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.ObjectInputStream;
import java.io.ObjectOutputStream;
import java.io.Serializable;

public class Xuliehua {
public static void main(String[] args) {
	objectWrite();
	try {
		objectRead();
	} catch (Exception e) {
		// TODO Auto-generated catch block
		e.printStackTrace();
	}
}
//对象反序列化，读磁盘上的文件到内存中变成对象使用
public static void objectRead() throws Exception{
	ObjectInputStream objectInputStream = new ObjectInputStream(new FileInputStream("d:\\c.txt"));
	User user = (User) objectInputStream.readObject();
	System.out.println(user);
	
}
//对象序列化，写出到磁盘保存
public static void objectWrite(){
	ObjectOutputStream outputStream = null;
	User user = new User("xiaowei",20);
	try {
		outputStream = new ObjectOutputStream(new FileOutputStream("d:\\c.txt"));
		outputStream.writeObject(user);
		
	} catch (FileNotFoundException e) {
		// TODO Auto-generated catch block
		e.printStackTrace();
	} catch (IOException e) {
		// TODO Auto-generated catch block
		e.printStackTrace();
	} finally{
		if(outputStream != null)
			try {
				outputStream.close();
			} catch (IOException e) {
				// TODO Auto-generated catch block
				e.printStackTrace();
			}
	}
}
}

class User implements Serializable{
	private String name;
	private int age;
	
	public User() {
		super();
		// TODO Auto-generated constructor stub
	}
	public User(String name, int age) {

	}

	}
