Garbage Collection in Java Explained: Types, Phases & Tuning for Optimal Performance

In this video, we dive into the fundamentals of Garbage Collection (GC) in Java, covering its importance in managing memory and optimizing the performance of your Java applications. Whether you're a beginner or an advanced Java developer, understanding garbage collection is key to avoiding memory leaks and improving your application's efficiency.

What you'll learn:
Types of Garbage Collectors: Learn the differences between Serial GC, Parallel GC, CMS GC, G1 GC, ZGC, and Shenandoah GC, and how to choose the best one for your application.
Garbage Collection Phases: Understand the Mark, Sweep, and Compact phases and how each garbage collector handles memory.
Tuning Garbage Collection: Explore how to fine-tune garbage collection by adjusting heap size, selecting the appropriate GC, and using tools like VisualVM and GC logs to monitor and optimize performance.
Why it's important:
Garbage collection is crucial for optimizing memory management in Java applications. Tuning it properly can drastically improve performance, reduce latency, and help you avoid common errors like OutOfMemoryError. This tutorial will equip you with the knowledge to fine-tune GC for your specific needs, making your Java apps faster and more efficient.
