• Create a class called Date that includes 3 instancevariables—a month (type int), a day (type int), and a year (type int). Provide a constructor thatinitializes the 3 instance variables and assumes the values provided are correct. Provide a set anda get method for each instance variable. Provide a method displayDate that displays the month,day, and year separated by forward slashes(/). Write a test application named DateTest thatdemonstrates class Date’s capabilities.Exercise 8.4 JHTP (Rectangle Class): Create a class Rectangle with attributes length andwidth, each of which defaults to 1. Provide methods that calculate the rectangle’s perimeter andarea. Use set and get methods for both length and width. The set methods will verify that lengthand width are each floating-point numbers larger than 0.0 and less than 20.0. Write a program totest class Rectangle.Notes:1. In the test class write code to create and print a menu that returns a value corresponding to themenu choice.a.set lengthb.set widthc.exit2. Also in the test file, remember to code a Try Catch Illegial Argument Expection to determineif the user entered a length and width of 0.0-20.
