COP 2800, Java Programming,

Modify a Java program meeting the following requirements . Using the program provided, PrintCalendar, you are to modify the program to validate the year entered is numeric, positive, and the correct length of four digits. You will also validate the month entered is from 1 to 12. If either is incorrect you need to create a Custom Exception class that states the problem, and allows the member to change either the year or month, using a Try...Catch block. Once you have validated the data you need to print out the calendar for the month entered.

At the beginning of the program add appropriate comments as in previous assignments.

Purpose: Modify a java program from detailed directions. Ability to:

Follow established programming standards for writing java programs Able to interrogate data Create a custom Exception Use the custom Exception with a try catch block

Use the print statement for output

Put your >.java file, pictures of code, proof of compile and output in a zipped file and upload in the Assignment 5 folder
