I’ve focused on two data structure categories, Java arrays and linked lists, which are the basis of more complex data structures such as stacks, queues, trees, graphs, dictionaries/maps, and sets.

Learn how to create and manipulate singly-linked lists in your Java code. You’ll also find out what algorithms are most commonly used to search and sort singly-linked lists.

The interfaces java.util.List and java.util.Set extend Collection, representing more specialized data structures and adding more operations and/or constraints.
