序列化和反序列化的应用

新建一个Student

import java.io.Serializable;

public class Student implements Serializable {
private String name;
private int gae;
private String sex;

public Student() {
}

public Student(String name, int gae, String sex) {
    this.name = name;
    this.gae = gae;
    this.sex = sex;
}

public String getName() {
    return name;
}

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

public int getGae() {
    return gae;
}

public void setGae(int gae) {
    this.gae = gae;
}

public String getSex() {
    return sex;
}

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

}

创建一个测试类

序列化以及反序列化

import java.io.*;

public class TestStu {
public static void main(String[] args){
//调用一下
m1();
//反序列化操作
Student s=null;
try {
FileInputStream fp = new FileInputStream(“a.txt”);
ObjectInputStream ob = new ObjectInputStream(fp);

        //读取一个对象
        s=(Student) ob.readObject();

        //释放资源
        ob.close();
        fp.close();
    } catch (FileNotFoundException e) {
        e.printStackTrace();
        return;
    } catch (IOException e) {
        e.printStackTrace();
    } catch (ClassNotFoundException e) {
        System.out.println("Employee class not found");
        e.printStackTrace();
    }

    //无异常直接输出
    System.out.println("Name:"+s.getName());
    System.out.println("Age:"+s.getGae());
    System.out.println("Sex:"+s.getSex());

}
public static void m1() throws IOException {
  //创建序列化对象
    Student s=new Student("武大郎",13,"男");
    ObjectOutputStream ob = new ObjectOutputStream(new FileOutputStream("a.txt"));
    ob.writeObject(s);
    ob.close();
}

}
