[Java 12 IO] Serializable 初步 ObjectOutputStream ObjectInputStream 將序列化的對象打出來

Person 類， 序列化後就表明對象能夠做爲二進制的數據流進行傳輸

package com.qunar.basicJava.javase.io.serializable;

import java.io.Serializable;

/**
 * Author: libin.chen@qunar.com  Date: 14-6-6 10:21
 */
public class Person implements Serializable {
    private String name;
    private int age;
    public Person(String name, int age) {
        this.name = name;
        this.age = age;
    }

    @Override
    public String toString() {
        return "姓名 ： " + this.name + "; 年齡 ： " + this.age;

    }
}

ObjectOutputStream 將序列化後的對象寫入到文件中

package com.qunar.basicJava.javase.io.serializable;

import java.io.*;

/**
 * Author: libin.chen@qunar.com  Date: 14-6-6 10:25
 */
public class SerDemo01 {
    public static void main(String[] args) throws IOException {
        File file = new File("/home/hp/tmp/test.txt");
        ObjectOutputStream objectOutputStream = null;
        OutputStream outputStream = new FileOutputStream(file);
        objectOutputStream = new ObjectOutputStream(outputStream);
        objectOutputStream.writeObject(new Person("張三", 30));
        outputStream.close();

    }
}

 ObjectInputStream 將序列化的對象傳回來

package com.qunar.basicJava.javase.io.serializable;

import java.io.*;

/**
 * Author: libin.chen@qunar.com  Date: 14-6-6 10:27
 */
public class SerDemo02 {
    public static void main(String[] args) throws IOException, ClassNotFoundException {
        File file = new File("/home/hp/tmp/test.txt");
        ObjectInputStream objectInputStream = null;
        InputStream inputStream = new FileInputStream(file);
        objectInputStream = new ObjectInputStream(inputStream);
        Object object = objectInputStream.readObject();
        objectInputStream.close();
        System.out.println(object);

    }
}
