In java using netbeans , Also do not put into a string

Create a method called getLastDigit that will return the last digit in an integer variable. Your method should take as an argument a single int variable. The method should return the last digit in that number.

For instance, if I have an int variable as follows

int x = 2563;

The last digit would be a 3 and that is the value that should be returned. Please notice that this is an int NOT a string.

Note:

You should investigate the Character.isdigit method. It will simplify your code a great deal. Also do not put into string.
