Answer:

import java.util.Scanner;

 

public class Exercise6 {

 

public static void main(String[] args) {

 Scanner in = new Scanner(System.in);

   

 System.out.print("Input first number: ");

 int num1 = in.nextInt();

   

 System.out.print("Input second number: ");

 int num2 = in.nextInt();

   

 

 System.out.println(num1 + " + " + num2 + " = " +  

 (num1 + num2));

   

 System.out.println(num1 + " - " + num2 + " = " +  

 (num1 - num2));

   

 System.out.println(num1 + " x " + num2 + " = " +  

 (num1 * num2));

   

 System.out.println(num1 + " / " + num2 + " = " +  

 (num1 / num2));

 

 System.out.println(num1 + " mod " + num2 + " = " +  

 (num1 % num2));

}

 

}

Explanation:

Sample Output:

Input first number: 125                                                                                        

Input second number: 24                                                                                        

125 + 24 = 149

125 - 24 = 101

125 x 24 = 3000

125 / 24 = 5

125 mod 24 = 5
