How do I do this using basic java without using hash mat

Using the attached UML class diagram, create a class for each of the classes using inheritance. Write a program that does the following:

Creates one object for each of the classes

Create an array to hold these objects and add the object references to the array

Using a for loop, traverse the array and execute toString on each of the object references in the array

Upload one zip file containing all of your java code and a snip of the output of running your program to show that it works.

Notes:

addCredits adds course credits to the tally for the student. For example, a student needs 132 credits to graduate and most classes are 2, 3, or 4 credits. When a student passes a course, credits can be added to their tally.
