Class design requirements:program should contain the following classes. Indentation indicates which classes are inner to others. Student RecordManager - Private inner class TranscriptPrinter Student Here are the requirements for each class: Student RecordManager: Contains a list of Students. Course - Static inner enum Grade that has at least the following instances: A, B, C, D, F Tester Has the following instance methods: getStudent, removeStudent, addStudent, searchByID (which takes one integer and returns a Student with that ID, or null if no such student exists). Instance method void printTranscript, which takes a Student argument and prints to the screen the Student's first name, last name, ID, and courses, with grade for each course. This method body must delegate the work to an instance of TranscriptPrinter. It could be a single line. Instance method void printAllTranscripts, which does the same as above, but for all students, one after the other. This method body must delegate the work to an instance of TranscriptPrinter. It could be a single line. Finally: iterator(), which must return an Iterator for the list of Students. TranscriptPrinter: (Inner class) Inner class to StudentRecordManager. Actually does the printing to screen of transcripts. You can design this class any way you wish. Student: Contains a list of Course objects, a String first name, a String last name, and an integer ID. Has setter and getter methods for first name, last name, and ID. Has a method to add a Course to this Student's Course list. (A method to remove a Course is not required). A method to get the list of courses. (Normally, we would probably want an iterator over them, but returning the actual list is fine for this project). Course: Has instance variables String name and Grade grade. Has getter methods for each. Setters are optional (You can, if you wish, just initialize these values in the constructor). Grade: Static nested enum to Course. Don't be intimidated! Remember, enums are just classes whose list of instances are all created at startup (and which cannot be constructed thereafter). Has at least the following instances: A, B, C, D, F. Others are optional. Tester: Creates a Student RecordManager with at least five Students. Calls printTranscript. Calls printAll Transcripts. Searches for a Student that exists, by ID, and prints that Student's first and last name. Removes a Student (could be the one from previous step, or any other, your choice). calls printAllTranscripts a second time. Note: These should be done in the above order!
