Answer from AI
The JVM has the following main memory areas:
-
Heap — an area for dynamic object allocation. All objects created during program execution are stored here. Managed by the garbage collector.
-
Stack — each thread has its own stack, which stores method call frames, local variables, and parameters.
-
Method Area (or Metaspace in newer JVM versions) — stores information about loaded classes, constants, static variables, and method bytecode.
-
Program Counter (PC) Register — points to the current instruction being executed in the thread.
-
Native Method Stack — stack for executing native (non-Java) methods.
Each area is responsible for a specific aspect of Java program execution and is managed by the JVM to ensure correct operation and optimize performance.
