    fun main(args: Array<String>) { 
      println("Initial Out put with a = 15, b = 10") 
      var calculator:ReactiveCalculator = ReactiveCalculator(15,10) 
      println("Enter a = <number> or b = <number> in separate      lines\nexit to exit the program") 
      var line:String?

        calculator.handleInput(line) 
      } while (line!= null && !line.toLowerCase().contains("exit")) 
    } 

If you run the code, you'll get the following output:

In the main method, we are not doing much operation except for just listening to the input and passing it to the ...
