对象流

ObjectInputStream:对象输入流

ObjectOutputStream:对象输出流

此流可以往文件中存取对象

 

案例：

package com.tanghaibin.io;

import java.io.File;
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;

import org.junit.Test;

public class ObjectInputStreamDemo {
 
 ObjectInputStream ois = null;
 ObjectOutputStream oos = null;
 String path = "G:"+ File.separator+"io"+File.separator+"object.txt";
 
 @Test
 public void objectOutput() throws FileNotFoundException, IOException{
  
  Person person = new Person("simple",14);
  
  oos = new ObjectOutputStream(new FileOutputStream(path));
  
  oos.writeObject(person);
 }
 
 
 @Test
 public void objectInput() throws FileNotFoundException, IOException, ClassNotFoundException{
  
  ois = new ObjectInputStream(new FileInputStream(path));
  
  Person person = (Person) ois.readObject();
  
  System.out.println(person.getName()+":"+person.getAge());
 }
}

class Person implements Serializable{
 private String name;
 private transient int age;
 
 public Person(String name, int age) {
  this.name = name;
  this.age = age;
 }
 public String getName() {
  return name;
 }
 public void setName(String name) {
  this.name = name;
 }
 public int getAge() {
  return age;
 }
 public void setAge(int age) {
  this.age = age;
 }
 
}
