Question

Design a class named largeIntegers such that an object of this class can store an integer of any number of digits. Add operations to add, subtract, multiply, and compare integers stored in two objects. Also add constructors to properly initialize objects and functions to set, retrieve, and print the values of objects. Write a program to test your class. g

Answer 1

Answer:

Here the code is given as follows,

Explanation:

Code:

import java.util.Scanner;

//created class named largeintegers

class largeintegers{

   //class can hold a long number

   long number;

   //constructor to set number

  largeintegers(long number){

      this.number=number;

  }

  //getNumber method to get number

  long getNumber(){

      return number;

  }

  //below are some basic operations

  long addition(long num1,long num2){

       return num1+num2;

   }

   long subtract(long num1,long num2){

       return num1-num2;

   }

   long multiply(long num1,long num2){

       return num1*num2;

   }

   boolean compare(long num1,long num2)

   {

       return num1>num2;

   }

  public static void main(String[] args) {

      //declared to long numbers

      long number1,number2;

      //scanner class to take user input

      Scanner sc= new Scanner(System.in);

      //taking input numbers

      System.out.println("Enter a Number ");

      number1=sc.nextLong();

      System.out.println("Enter 2nd Number :");

      number2=sc.nextLong();

      //created two objects

      largeintegers object=new largeintegers(number1);

      largeintegers object2=new largeintegers(number2);

      //displaying two numbers

      System.out.println("Entered Numbers ");

      System.out.println(object.getNumber());

      System.out.println(object2.getNumber());

      //calling basic methods using created objects

      System.out.println("Some Operations on Given two Numbers ");

      System.out.println("Addition:"+object.addition(object.getNumber(), object2.getNumber()));

      System.out.println("Subtraction:"+object.subtract(object.getNumber(), object2.getNumber()));

      System.out.println("Multiplication:"+object.multiply(object.getNumber(), object2.getNumber()));

      System.out.println("Comparison:");

      if(object.compare(object.getNumber(), object2.getNumber())==true)

      {

          System.out.println("First Number is Greater than Second Number ");

      }

      else

      {

          System.out.println("Second Number is Greater than First Number ");

      }

      sc.close();

  }

}

Output:-
