Course Highlights:

• Java Fundamentals: Understand why Java is not 100% Object Oriented and whether Java uses Pass by Value or Pass by Reference. 🤓
• Advanced Concepts: Learn about Covariant return type, Equals and Hash Code contract, and the immutability of String in Java. ⚛️
• Performance Tuning: Discover what JIT compiler does and why pointers are not used in Java. 🚀
• Design Patterns & Best Practices: Explore how to make a class Immutable, implement the Singleton design pattern, and understand how to break it (for educational purposes, of course). 🔧
• Collections Framework: Dive into the Collection Hierarchy, understand the nuances between List, Set, Queue, and Map interfaces, and explore the difference between fail fast and fail safe Iterators. 📚
• Concurrency: Learn about Blocking Queues, the differences between synchronized collections and concurrent collections, and the internal workings of HashMap. 🔁
• Java 8 & Beyond: Find out why Java 8 was introduced and its advantages, as well as what Lambda expressions are. 🎉
