IN JAVA PLEASE

thank you

Implement the classes in the class diagram. By my count, I see 12 classes which means you should have 12 separate class files Add a new class (not shown on the class diagram) called Course. Provide properties for course name, section number, room, designator (e.g., CS 17.11), classroom, and number of units. Provide at least two CTORs (default and another that allows you to specify all required properties.) Modify all classes in the class diagram to include a .toString) method that returns appropriate data for that class. Note, it is not acceptable to use the IDE provided template for .toString) you must write your own implementation Modify class Student to include a new ArrayList(Course). Name it appropriately In main, create an instance of two students, one of whom is you, the other can be made up. Populate your information with that appropriate to you. You must include at least one (dummy) address and phone number (nobody is going to see it so you can put your real address/phone if you wish, or simply use the JC's address). Add at least two courses for yourself (if you've only taken one course at the JC, look at the online catalog and pick another. Create at least two instances of an Instructor and two of an Administrator. Pick names from the college website if you need to. You should now have 6 objects 2 students, 2 instructors, and 2 administrators. Create an ArrayList
