+      Create a sub-folder in the main app folder with a unique name for your work.
+        Design at least one custom class that represents a real-world object. //Object: Xbox HashMap
+          You must also incorporate an enum type as well.
+            Genre
+          The class must have at least one constructor.
+            I have this
+          The class must have at least 3 member functions.
+            I need this to be added maybe I can do addGame, removeGame, and getGame
+          One of your functions must make use of a conditional expression.
+            I can do this with the addGame method by implementing a check if the xbox has a disk drive && if the disk drive is empty
+
+          One of your functions must make use of your collection member variable.
+            I can do this with the getGame method by calling the games inside of the hashmap
+
+          One of your functions must make use of a loop.
+            I can do this with the removeGame method by using a for loop to iterate through the games and remove the game that matches the id passed in.
+          You must use at least one custom exception.
+
+            I can do this with the addGame method by creating a custom exception that checks if the disk drive is empty and throws an exception if it is not.
+          Create a matching subfolder in the test folder and a test file. Your test must include at least 5 test methods.
+            Tests: 
+              1. testAddGame
+              2. testRemoveGame
+              3. testGetGame
