Memory Management

About

Memory management in the JVM is a critical aspect that ensures efficient allocation, usage, and reclamation of memory resources. The JVM provides an automatic memory management system through Garbage Collection (GC), optimising application performance and preventing memory leaks.

  1. Memory Areas → The JVM divides memory into different regions for efficient execution.

  2. Heap & Non-Heap Memory → Objects are stored in the Heap, while metadata and code are in Non-Heap.

  3. Garbage Collection → JVM automatically removes unused objects to free up memory.

  4. Stack & Thread Memory → Manages method calls, local variables, and thread execution.

  5. Performance Optimization → JVM tuning parameters (-Xms, -Xmx, -XX:GC) help optimize memory usage.
