对象序列化和反序列化-蒲公英云

对象序列化和反序列化

对象序列化就是将0bject转化成byte序列，反之叫对象的反序列化。

序列化的对象要实现Serializable接口

类：

public class Student implements Serializable{
    private static final long serialVersionUID = -5878823330113310798L;
    private String stuno;
    private String stuname;
    private int stuage;
    public Student(){
    }
    public Student(String stuno,String stuname,int stuage){
        this.stuno=stuno;
        this.stuname=stuname;
        this.stuage=stuage;
    }
    public int getStuage() {
        return stuage;
    }
    public void setStuage(int stuage) {
        this.stuage = stuage;
    }
    public String getStuname() {
        return stuname;
    }
    public void setStuname(String stuname) {
        this.stuname = stuname;
    }
    public String getStuno() {
        return stuno;
    }
    public void setStuno(String stuno) {
        this.stuno = stuno;
    }
    public String toString(){
        return "["+stuno+","+stuname+","+stuage+"]";
    }
}
public class ObjectSeriaDemo1 {
    public static void main(String[] args) throws Exception{
      String file="demo/obj.dat";
      //1.对象的序列化
        /*ObjectOutputStream oos=new ObjectOutputStream(
                new FileOutputStream(file)
        );
        Student stu=new Student("10001","张三",20);
        oos.writeObject(stu);
        oos.flush();
        oos.close();*/
        //2.反序列化
        ObjectInputStream ois=new ObjectInputStream(
                new FileInputStream(file)
        );
        Student stu=(Student)ois.readObject();
        System.out.println(stu);
        ois.close();
    }
}
