Java, they must understand how to effectively use Java collections in their daily work. This course offers you a deep dive into the framework and hands-on experience working with it. The Java Collections framework consists of interfaces, implementations, and utilities that together provide standard support for common data structures in the language. Instructor Kevin Bowersox explains these things, then goes into real examples of techniques for working with them, like creating different collections types and iterating them. He covers operations and interfaces such as List (including both ArrayList and LinkedList), Queue, Deque, and Map. Kevin concludes with a discussion of how you can use Java Collections utilities to sort elements, search collections, use comparators, and more. </div> <button class="show-more-less-html__button
