What areas of memory, besides the stack and heap, can you name?

Metaspace: Stores class metadata, including information about classes, methods, and the runtime constant pool.

Direct Memory: Used for direct access to the operating system's memory, bypassing the JVM, often via ByteBuffer.

JIT Code Cache: The area where compiled native code generated by the Just-In-Time (JIT) compiler is stored.

Thread Stacks: Each thread in Java has its own stack for storing local variables and method calls. Although often considered part of the overall "stack" concept, each thread has its own separate stack.
