Explanation / Answer

CASE 1

I tried your code, there is nothing wrong with your code, your are getting that error, because, you must have entered String,Float value. Because, when i entered, numeric value, it runs without any error. But, once, i entered String,float. It throw the same exception, which you have mentioned in your question.

CASE 2

You would have entered something, which would be out of range of INT.

Note : Please enter number one by one, not in the same line. I mean, enter 2 and then press enter key and then enter second number 6 or whatever followed by enter key and so on.
I request you to kindly comment or mention the input you gave to the program,that generated this error,then I shall be able to give you the exact reason for error.
