About this course
Working with data is the core of Java development, and mastering collections is essential for building scalable applications. If you struggle to choose between an ArrayList and a HashSet, this course provides the foundational knowledge you need.
By the end of this course, you will have a deep understanding of the Java Collections Framework (JCF) hierarchy, including interfaces like List, Set, and Map. You will be able to efficiently store, retrieve, and manipulate data, write concise code using modern Java features like streams, and even practice implementing your own custom data structures.
What you'll learn:
* Understand the fundamental interfaces (Collection, List, Set, Map) and their primary implementations.
* Apply generics and type safety rules to ensure robust and error-free collection usage.
* Analyze the performance trade-offs between different collection types (e.g., ArrayList vs. LinkedList, HashMap vs. TreeMap).
* Practice common operations like iteration, searching, and sorting data using comparators and the Collections utility class.
* Utilize modern Java Streams and Lambda expressions for concise and efficient data processing and filtering.
* Create and implement a basic custom collection structure to deepen your understanding of data management principles.
We start by defining key terminology and exploring the Collection hierarchy before moving into practical examples for Lists, Sets, and Maps. The course culminates in advanced topics like sorting, immutability, and building custom solutions. This course is designed specifically for beginner Java developers. No prior experience with the Java Collections Framework is required, only basic familiarity with Java syntax and object-oriented programming concepts.
