Serialization and deserialization of objects

Person_ Class 1:

import java. io. Serializable; public class Person_ 1 implements Serializable { private String name; private int age; public Person_1(String name,int age) { super(); this.name = name; this.age = age; } public Person_ 1() { super(); } 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; } @ Override public String toString() { return "Person [name=" + name + ",age=" + age + "]"; }

}

Demo class:
