Create a class called SimpleDate that includes three instance variables - a month, a day and a year (all type int). Provide a constructor that initializes the three instance variables and validates that those values are correct (follow calendar rules) and throws an exception for incorrect values. Provide a set and get method for each instance variable.
Provide a toString method override that displays the month, day and year separated by forward slashes (/).
Write a test application named SimpleDateTest that demonstrates class SimpleDate's capabilities
