Which components are responsible for data storage and memory management within the JVM?

Answer from AI
Inside the JVM, several key components are responsible for data storage and memory management:
-
Heap — the memory area where objects and arrays are stored. The JVM manages allocation and garbage collection in this area.
-
Stack — a stack is created for each thread, where local variables, method parameters, and return addresses are stored.
-
Metaspace — the memory area where class metadata is stored (formerly PermGen).
-
Garbage Collector (GC) — an automatic garbage collection mechanism that frees memory occupied by unused objects.
-
Native Memory — memory allocated outside the JVM, for example, for JNI or internal structures.
Thus, the JVM manages memory through division into stack and heap, as well as through the garbage collector, which automatically frees unused memory.
