Java序列化，怎么把一个类，序列化到一个文件中去呢？

Question

已经有一个文件，想把类序列化到文件中，然后再从文件中反序列化，怎么实现呢？

Answer 1

//创建一个可序列化类Person
import java.io.Serializable;

public class Person implements Serializable{

private String name;
private String sex;

public Person(String name,String sex){
    this.name=name;
    this.sex=sex;
}

public String getName() {
    return name;
}

public void setName(String name) {
    this.name = name;
}

public String getSex() {
    return sex;
}

public void setSex(String sex) {
    this.sex = sex;
}   

}
//测试类
public class TestDemo {

public static void main(String[] args) {
    //创建一个对象
    Person people = new Person("张三","男");
    try {
        //实例化ObjectOutputStream对象
        ObjectOutputStream oos = new ObjectOutputStream(new FileOutputStream("C:\\person.txt"));
        //将对象写入文件
        oos.writeObject(people);
        oos.flush();
        oos.close();

        //实例化ObjectInputStream对象
        ObjectInputStream ois=new ObjectInputStream(new FileInputStream("C:\\person.txt"));

        try {
            //读取对象people,反序列化
            Person p = (Person)ois.readObject();
            System.out.println("姓名："+p.getName());
            System.out.println("性别："+p.getSex());
        } catch (ClassNotFoundException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }


    } catch (FileNotFoundException e) {

        e.printStackTrace();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}

}
