Question

Define a class Calculation as follows: [5]

Data Member/ Instance Variables: N (integer type) and W, res1, res2 and res3 (all

double

Member Functions/Methods:

void Accept() : Input values of N and W from the user

void Process(): To find the N raised to the power 3 and square of W, then store

the results in variables res1 and res2. Also find the sum of results in res1 and res2

and store in variable res3.

void Show(): to print the values of N, W, res1, res2 and res3 as the output

Write a main () function to create suitable object of the class and call the methods

to print he result.​

Answer 1

Program :

import java.util.*;

public class MyClass {

   int N ;

   double W , res1 , res2 , res3;

   void Accept()

   {

       Scanner Sc = new Scanner(System.in);

       System.out.print("Enter a number : ");

       N = Sc.nextInt();

       System.out.print("Enter a number : ");

       W = Sc.nextDouble();

   }

   void Process()

   {

       res1 = N * N * N;

       res2 = W * W;

       res3 = res1 + res2;

   }

   void Show()

   {

       System.out.println(N);

       System.out.println(W);

       System.out.println(res1);

       System.out.println(res2);

       System.out.println(res3);

   }

   public static void main(String args[])

   {

       MyClass m = new MyClass();

       m.Accept();

       m.Process();

       m.Show();

   }

}
