/*
* Create a User Interface to perform Integer Division. The user enters two
* numbers in text fields, Num1 and Num2. The division of Num1 and Num2 is
* displayed in the result field when the divide button is clicked. If Num1 or
* Num2 were not integer, the program would throw a NumberFormatException, If
* Num2 is Zero, the program would throw an Arithmetic Exception. Display the
* Exception in message box.
