Java Exception Handling

[Darr2cool78]

Ok so i made a program to take a user input from keyboard of a desired N**th Li**ne for Pas**cals Tr**ang**le and display it! Our teacher says we get extra marks for adding an exception handler for say a int value not being entered..any help would be greatly apreciated..
