Need Help completing these codes. I have most of the code written down need assistance with this portion of the code. Thank you!!

Create a Part 3 subpackage p3 under the ca5 package and copy here all the classes from subpackage p2. In the Shape class in the p3 subpackage, modify the compareTo method so that shapes with larger areas precede shapes with smaller areas. In the Shape class, modify the maxAreaShape2 method so that it uses the modified compareTo method and still returns the shape in the input list with the largest area. Run the same main method of the ShapeTest class in the p3 subpackage. What do you observe of the list of shapes after sorting
