Java 11 Fundamentals

Collections

In this course, you will learn why you would want to use collections instead of arrays and understand the power of lists, sets, and maps.

Working with data is fundamental to any business problem. In this course, Java Fundamentals: Collections, you will learn about Java Collections - data structures designed to store and process data in memory. First, you will discover why you would want to use collections instead of arrays. Then, you will cover the capabilities of lists, sets, maps, and also the different data structure tradeoffs. Finally, you will explore important collection algorithms and how different collection implementations work. By the end of this course, you will know how to use Java Collections to process data.
