Unit 3. Linked Lists

This unit is about (wait for it) linked lists! Rather than store information in an array, linked lists are a collection of objects that link to each other like links in a chain. In other words, each object (usually called a node) usually has a reference to one or two other links.

There is a LinkedList class in Java which implements the List interface. However, to better understand how it works, we will make a simple linked list class of our own.

Starting with this unit, we will begin to use the site codeboard.io. Please make an account there.
