    There are methods in the System class that will return the current time.
    Get the time at the start and end and subtract.

    You were the one watching the code run. Does about 1/2 second look right?

    Put in a loop that goes a million times and see how long that takes.

    i meant in terms of a simple program is that a good run time but its fine it seems to be running at around .03 ms per input. in a linear fashion so i guess its good.
