Below java class will explain you how to use the Scanner object which is a part of java.util package. This class is basically for integer values only however you can use the same way for double, float etc.

import java.util.Scanner; public class Calculator { public static void main(String[] args) { Scanner in = new Scanner(System.in); System.out.println("Enter your first integer value: "); int first = in.nextInt(); System.out.println("Enter your second integer value: "); int second = in.nextInt(); int plus = first + second; int minus = first - second; int multiply = first * second; int divide = first / second; System.out.println("Summation for " + first + " and " + second + " is: \t\t" + plus); System.out.println("Subtraction for " + first + " and " + second + " is: \t\t" + minus); System.out.println("Multiplication for " + first + " and " + second + " is: \t" + multiply); System.out.println("Division for " + first + " and " + second + " is: \t\t" + divide); } }

__Output:__Enter your first integer value: 50 Enter your second integer value: 50 Summation for 50 and 50 is: 100 Subtraction for 50 and 50 is: 0 Multiplication for 50 and 50 is: 2500 Division for 50 and 50 is: 1
