JavaI/O文件读写:对象输出流

对象输出流  ObjectOutputStream

将对象信息写入本地文件

pojo

package cn.xtnotes.pojo;

import java.io.Serializable;

public class Stu implements Serializable{
	public String name;
	public int age;
	public String lo;
	public Stu(String name, int age, String lo) {
		this.name = name;
		this.age = age;
		this.lo = lo;
	}
}

main

package IO;

import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.ObjectOutputStream;
import java.io.Serializable;
import java.util.ArrayList;

import cn.xtnotes.pojo.Stu;

public class PIs {

	public static void main(String[] args) {
		Stu stu1=new Stu("张1",15,"吃饭");
		Stu stu2=new Stu("张2",15,"吃饭");
		Stu stu3=new Stu("张3",15,"吃饭");
		Stu stu4=new Stu("张4",15,"吃饭");
		ArrayList<Stu> al=new ArrayList<Stu>();
		al.add(stu1);
		al.add(stu2);
		al.add(stu3);
		al.add(stu4);
		ObjectOutputStream oss=null;
		try {
			oss=new ObjectOutputStream(new FileOutputStream("C:\\t\\1.txt"));
			oss.writeObject(al);
			oss.flush();
		} catch (FileNotFoundException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}finally {
			try {
				oss.close();
			} catch (IOException e) {

对象写入文件为乱码，可通过下节课对象输入流， 判断该文件输入后内容是否正确
