Answer to Question #295652 in Java | JSP | JSF for Khizee

Question

Create a simple calculator application in Java which will perform four basic

arithmetic operations (plus, minus, multiplication and division) on a pair of

numbers (input from user) from 0 – 9, except division by zero. It means, this

program will perform arithmetic operations between single digits only, but the

result can be more than one digit and in decimals, obviously. Sample output is

given below:

Enter first number between 0 and 9: 6

Enter second number between 0 and 9: 4

Applying arithmetic operations:

Adding 6 and 4 results = 10

Subtracting 4 from 6 results = 2

Multiplying 6 with 4 results = 24

Dividing 6 by 4 results = 1.5

Answer 1

import java.util.Scanner;


class App {


	public static void main(String[] args) {
		Scanner keyBoard = new Scanner(System.in);
		System.out.print("Enter first number between 0 and 9: ");
		int n1 = keyBoard.nextInt();
		System.out.print("Enter second number between 0 and 9: ");
		int n2 = keyBoard.nextInt();


		System.out.println("Applying arithmetic operations:");
		int result = n1 + n2;
		System.out.printf("Adding %d and %d results =  %d\n", n1, n2, result);
		result = n1 - n2;
		System.out.printf("Subtracting %d from %d results =  %d\n", n1, n2, result);
		result = n1 * n2;
		System.out.printf("Multiplying %d with %d results =  %d\n", n1, n2, result);
		double resultDiv = (double) n1 / (double) n2;
		System.out.printf("Dividing %d by %d results =  %.1f\n", n1, n2, resultDiv);
		keyBoard.close();
	}
}
