Master Java Collections Framework, Generics, Lambdas, and Stream API from scratch to PRO level with practical coding exercises.

Description

The Java Collections Framework is essential knowledge for any Java developer. Most developers learn the basics but never master the advanced features that separate junior from senior engineers. This course takes you from scratch to PRO level, covering all collections from the Collection hierarchy (List, Set, Queue), different containers from the Map hierarchy (HashMap, TreeMap, LinkedHashMap), Iterable and Iterator, hash tables, binary tree based collections, Generics, Lambda Functions, Method References, and the Stream API.

This Course Offers

  • Complete Java Collections Framework from scratch to PRO: Learn different collections from the Collection hierarchy (List, Set, Queue) and different containers from the Map hierarchy (HashMap, TreeMap, LinkedHashMap). Understand real life examples of using collections.
  • Generics mastery: Learn Generics in Java, including how to write type safe code and create reusable components. Understand how generics work with collections.
  • Functional Programming with Lambdas and Method References: Learn Functional Programming concepts and how to apply them with collections. Master Lambda Functions and Method References for writing clear, concise code.
  • Stream API for modern Java development: Learn Stream API for processing sequences of data. Understand how to write clear and concise code in Java with the help of lambdas and Stream API while working with collections.

The Collections Framework is not just about choosing between ArrayList and LinkedList. It is about understanding hash tables, binary trees, generics, lambdas, and streams. The question is whether you want to master these concepts from scratch to PRO level with practical exercises, or stay at the junior level where you only know the basics.
