Answer to Question #250086 in Java | JSP | JSF for Amadix

Question

Using a switch statement, write a program that prompts the user for a numeric code and two operands. The numeric codes of 1, 2, 3, and 4 represents addition, subtraction, multiplication, and division respectively. Before division, your program should check whether the second operand is not zero. If it is, it should display “Division by zero not allowed” to the screen.

Answer 1

import java.util.Scanner;
public class Main {
    public static void main(String[] args) {
		Scanner in = new Scanner(System.in);
		System.out.println("Enter the operation to perform: ");
        System.out.println("1.Addition\n2.Subtraction\n3.Multiplication\n4.Division");
		int option = in.nextInt();
		System.out.println("Enter the two numbers to perform the operation: ");
		System.out.print("Operand 1: ");
		int X = in.nextInt();
		System.out.print("Operand 2: ");
		int Y = in.nextInt();
		double total;
		switch (option) {
		case 1:
		{
			total = X + Y;
			System.out.println("Addition of the two numbers is = " + total);
		}
			break;
		case 2:
		{
			total = X - Y;
			System.out.println("Subtraction of the two numbers is = " + total);
		}
			break;
		case 3:
		{
			total = X * Y;
			System.out.println("Multiplication of the two numbers is = " + total);
		}
			break;
		case 4:
		{
			if (Y != 0) {
				total = X / Y;
				System.out.println("Division of the two numbers is= " + total);
			} else {
				System.out.println("Division by zero not allowed");
			}
		}
			break;

		in.close();
