Hey All I have this Java HW that i would need help with.. I have posted the instructions below and the testcases at the bottom...

You will not actually be drawing the shapes in this program, rather, you will simply be representing geometric shapes as objects and providing the ability to place them in space. The workspace will make use of a List from the Java Standard Library to collect shapes and will have methods that allow you to add, remove, and inspect the shapes it contains. All of the shapes share a common set of methods defined by a Java interface. The behavior of these common methods varies as appropriate, by shape. In addition, each shape has one or more methods unique to it. The following shapes will be supported: circle, rectangle, and triangle Objectives . To develop and demonstrate basic object-oriented development skills. Much of the structure of the solution is given use good judgment when "filling in the blanks". . To become familiar with Java interfaces and the concept of polymorphism . To practice using the instanceof operator More practice using existing classes and interfaces from the Java Standard Library, such as List, ArrayList, LinkedList, Point, and color Given Files Retrieve the provided test file for this The given file is a starter junit test file for your code. Be sure to add to this file to make sure your code is working properly. Your instructors have a much more extensive test file that they will test your implementation with! Ground Rules Many of the classes and interfaces you will be writing in this lab have counterparts in the Java Standard Library. You may not use the Java Standard Library versions in your implementation unless explicitly instructed to do so (see below). The Java Standard Library classes and interfaces you may use are identified by a complete package specification. For example, you will be using the java.awt.Color, java.awt. Point, and java.util.List classes/interfaces from the Java Standard Library. You may also use the java.lang.Math class from the Java Standard Library (even though it is not explicitly referenced in this document). Any classes or interfaces in the specifications below (other than Point, Color, and List) must be entirely written by you. If you have any questions regarding this restriction please be sure to ask your instructor early in the development process (ideally, before you of 4 2/3/2018, 10:24 PM
