Java JVM Architecture and Memory Management

Understanding how the Java Virtual Machine (JVM) works under the hood is the key to writing high-performance, scalable Java applications. This text-based course guides you through the inner workings of the JVM, starting with foundational concepts and moving to critical memory transitions like the shift from PermGen to Metaspace. What you'll learn: Understand the core components of the HotSpot JVM architecture; Analyze JVM memory areas including Heap, Stack, and Metaspace; Learn how default methods impact class loading; Explore modern garbage collection algorithms; Configure JVM parameters for optimal performance; Troubleshoot common memory issues. You will start with essential JVM terminology and architecture baselines before exploring class loading and memory layout changes through clear, structured explanations. This course is designed for beginner to intermediate Java developers who want to understand the platform beneath their code, with no prior system-level programming experience required.
