Exercise 3.11 — Find the Number of Days in a Month | Computer Science Programming Tutorials

Java program that prompts the user to enter a month and year and displays the number of days in the month. For example, if the user entered month 2 and year 2012, the program should display that February 2012 had 29 days. If the user entered month 3 and year 2015, the program should display that March 2015 had 31 days.
