Please could I have a typewritten answer.

Answer 1

//Java Code to Serialize and Deserialize the objects

import java.io.*;
import java.io.Serializable;
class Dog implements Serializable {
String breed;
int age;
String colour;

//Constructor of class Dog
public Dog(String breed, int age, String colour) {
this.breed = breed;
this.age = age;
this.colour=colour;
}
}

public class SerDeser{
public static void main(String args[])throws Exception{

//Creating object using constructor
Dog d =new Dog("BullDog", 2,"Brown");
FileOutputStream fout=new FileOutputStream("file1.txt");
ObjectOutputStream out=new ObjectOutputStream(fout); //converting objects into a stream
out.writeObject(d); //Writing object to a file
out.flush();
ObjectInputStream in=new ObjectInputStream(new FileInputStream("file1.txt")); //Reading Streams into objects
Dog d1=(Dog)in.readObject(); //Reading object from a file
System.out.println(d1.breed+" "+d1.age+" "+d1.colour); //Printing the object
in.close();
}
}

$javac SerDeser.java

$java SerDeser

BullDog 2 Brown
