Question

JAVA

~ Write a program to find all the arithmetic operations using switch case.​

Answer 1

Solution:

Given code is written in Java.

import java.util.Scanner;

public class Switch_Case{

   public static void main(String args[]){

       Scanner sc = new Scanner(System.in);

       int a, b, choice;

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

       a = sc.nextInt();

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

       b = sc.nextInt();

       System.out.println("1. Addition.");

       System.out.println("2.Subtraction.");

       System.out.println("3. Multiplication.");

       System.out.println("4. Division.");

       System.out.println("5. Remainder.");

       System.out.print("\nEnter your choice: ");

       choice = sc.nextInt();

       switch(choice){

           case 1:

           System.out.println("Result is: " + (a + b));

           break;

           case 2:

           System.out.println("Result is: " + (a-b));

           break;

           case 3:

           System.out.println("Result is: " + (a * b));

           break;

           case 4:

           System.out.println("Result is: " + (a / b));

           break;

           case 5:

           System.out.println("Result is: " + (a % b));

           break;

           default:

           System.out.println("Invalid Input.");

       }

   }

}

Explanation:

• At first, we ask the user to enter two numbers.
• Then we ask the user to enter their choice.
• Based on the choice entered, the required operation is carried out using switch case.
• For an invalid input, an appropriate message is displayed.

Output is attached.
