Java program to create arithmetic calculator

Write a Menu drive program to choose Arithmetic Operation and perform operation based on user choice:

 

import java.util.Scanner;
public class CalculatorWithSwitch 
{
    public static void main(String[] args) 
	{
        Scanner sc = new Scanner(System.in);
        System.out.print("Enter first number: ");
        double num1 = sc.nextDouble();
        System.out.print("Enter second number: ");
        double num2 = sc.nextDouble();
        System.out.println("Choose an operation:");
        System.out.println("1. Addition (+)");
        System.out.println("2. Subtraction (-)");
        System.out.println("3. Multiplication (*)");
        System.out.println("4. Division (/)");
        System.out.print("Enter your choice (1/2/3/4): ");
        int choice = sc.nextInt();
        double result = 0;
        switch (choice) 
		{
            case 1:
                result = num1 + num2;
                System.out.println("Result of addition: " + result);
                break;
            case 2:
                result = num1 - num2;
                System.out.println("Result of subtraction: " + result);
                break;
            case 3:
                result = num1 * num2;
                System.out.println("Result of multiplication: " + result);
                break;
            case 4:
                if (num2 != 0) {
                    result = num1 / num2;
                    System.out.println("Result of division: " + result);
                } else {
                    System.out.println("Error: Division by zero");
                }
                break;
            default:
                System.out.println("Invalid choice. Please enter a valid operation.");
                break;
        }
    }
}

Enter first number: 10

Enter second number: 5

Choose an operation:

1. Addition (+)

2. Subtraction (-)

3. Multiplication (*)

4. Division (/)

Enter your choice (1/2/3/4): 1

Result of addition: 15.0
