Enter a number: 12
Enter another number: 3
12 + 3 = 15
12 - 3 = 9
12 x 3 = 36
12 / 3 = 4 <
12 mod 3 = 0


Source Code:


import java.util.*;
public class Main
{
	public static void main(String[] args)
	{
		System.out.print("Enter a number: ");
		int number1 = Integer.parseInt(new Scanner(System.in).nextLine());
		System.out.print("Enter another number: ");
		int number2 = Integer.parseInt(new Scanner(System.in).nextLine());
		System.out.printf("%1$s + %2$s = %3$s" + "\r\n", number1, number2, number1 + number2);
		System.out.printf("%1$s - %2$s = %3$s" + "\r\n", number1, number2, number1 - number2);
		System.out.printf("%1$s x %2$s = %3$s" + "\r\n", number1, number2, number1 * number2);
		System.out.printf("%1$s / %2$s = %3$s" + "\r\n", number1, number2, number1 / number2);
		System.out.printf("%1$s mod %2$s = %3$s" + "\r\n", number1, number2, number1 % number2);
