Hello lfeoluwa,

Here is the complete program,

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));
}

}

If you have any query feel free to contact me.

Thanks

Hey Ifeoluwa Omobolanle, you can make the program for addition, subtraction, and multiplication of two numbers using different ways in Java. I am giving you the solution using switch...case:
import java.util.Scanner;

public class Calculate

{

   public static void main(String[] args)

   {

      int a, b, choice, add, sub, mul;

      Scanner s = new Scanner(System.in);

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

      a = s.nextInt();

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

      b = s.nextInt();

      while(true)

      {

         System.out.println("Enter 1 for addition");

         System.out.println("Enter 2 for subtraction");

         System.out.println("Enter 3 for multiplication");

         System.out.println("Enter 4 to Exit");

         choice = s.nextInt();

         switch(choice)

         {

            case 1:

            add = a + b;

            System.out.println("Result:"+add);

            break;

            case 2:

            sub = a - b;

            System.out.println("Result:"+sub);

            break;

            case 3:

            mul = a * b;

            System.out.println("Result:"+mul);

            break;

            case 4:

            System.exit(0);

         }

      }

   }

}

Hope you find this answer useful.

import java.util.Scanner;

public class JavaProgram
{
public static void main(String args[])
{
int first, second, add, subtract, multiply;
float devide;
Scanner scanner = new Scanner(System.in);
System.out.print("Enter Two Numbers : ");
first = scanner.nextInt();
second = scanner.nextInt();
add = first + second;
subtract = first - second;
multiply = first * second;
devide = (float) first / second;
System.out.println("Sum = " + add);
System.out.println("Difference = " + subtract);
System.out.println("Multiplication = " + multiply);
System.out.println("Division = " + devide);
}
}

Output :-

Enter Two Numbers : 12
5
Sum = 17
Difference = 7
Multiplication = 60
Division = 2.4
