explain to me while in this code, even though I am able to ask the user for an integer, it is now printing out the name twice.

For example, if the user enters john and then enters john for the integer, it will throw an exception, then I might type the integer 20. But once I type in end, it is printing out the name john two times. Where am I going wrong?
