Class MyHashMapFactory

lab08/src/hashmap/MyHashMapFactory.java:13–36

This is a helper factory class that allows us to test different bucket types without having to write a separate test for each one. You don't need to understand how this works. Please don't modify this class unless you REALLY know what you're doing. @author Noah Adhikari, Spring 2023
