jvm internals

JVM internals refer to the underlying architecture and mechanisms that enable the Java Virtual Machine (JVM) to execute Java applications. The JVM is responsible for loading class files, executing bytecode, and managing system resources. Key components include the class loader, which loads necessary classes, and the execution engine, which interprets and runs the bytecode. Additionally, the JVM incorporates features like garbage collection for memory management and Just-In-Time (JIT) compilation to enhance performance. Understanding JVM internals is crucial for optimizing Java applications and troubleshooting issues that may arise during execution.
