Collections in Java: Sets & Maps

“The Java collections framework has several different specialized collections such as sets and maps. These allow you to store values and data in different ways. In this course you ll explore these and other valuable collections from the Java collections framework.

Create and work with sets performing several different operations including union intersection difference and subset operations.

Next explore the different set implementations that Java offers beyond the basic HashSet. Discover how the LinkedHashSet and TreeSet differ in how elements of the set are accessed.

Finally work with another important and commonly used Java collection the map. Investigate several different map implementations and use maps to build a Least Recently Used cache and a priority queue.

When you re finished you ll have a solid foundational working knowledge in using special collections in the Java collections framework.”
