In this in-depth lecture, we take a deep dive into Java Heap Memory, one of the most critical yet misunderstood parts of JVM architecture. If you want to truly understand how Java manages memory, how garbage collection works internally, and how different reference types affect object lifecycle, this video will give you complete clarity from first principles. What You’ll Learn in This Video Java Heap Memory Internals What is Heap Memory and why it exists Object allocation process in JVM Structure of Heap: Young Generation (Eden + Survivor spaces) Old Generation (Tenured space) Object lifecycle and movement across generations Age counter and promotion logic Types of Memory References in Java Strong References (default behavior) Weak References (used in caching) Soft References (memory-sensitive caching) Phantom References (advanced use cases) How references affect Garbage Collection Practical examples of where each is used Garbage Collection (GC) Algorithms Explained Why Garbage Collection is needed Stop-The-World (STW) concept Different GC Algorithms: Mark & Sweep Mark & Compact Copying Algorithm Generational Garbage Collection concept How JVM optimizes memory cleanup Real-world GC behavior and performance impact Why Learn Java? Java is one of the most powerful and widely used programming languages in the world. It is used in: Backend development Enterprise applications Android development Banking systems Large-scale distributed systems If you want to master Data Structures, Spring Boot, Microservices, or System Design, Java fundamentals are essential.
