Problem:

Write an application that reads two floating point numbers and
prints their sum, difference, and product.

Output:

Enter the first number: 54
Enter the second number: 12
Their sum is: 66.0
Their difference is: 42.0
Their product is: 648.0

Solution:

import java.util.Scanner;

class FloatCalculations
{
   //-----------------------------------------------------------------
   //  Reads two floating point numbers and prints their sum,
   //  difference, and product.
   //-----------------------------------------------------------------
   public static void main (String[] args)
   {
      float num1, num2;
   Scanner scan = new Scanner (System.in);

      System.out.print ("Enter the first number: ");
      num1 = scan.nextFloat();
      System.out.print ("Enter the second number: ");
      num2 = scan.nextFloat();

      System.out.println ("Their sum is: " + (num1+num2));
      System.out.println ("Their difference is: " + (num1-num2));
      System.out.println ("Their product is: " + (num1*num2));
   }
}
