What are the different types of memory areas allocated by JVM?

 

In java, JVM allocates memory to different processes, methods and objects. Some of the memory areas allocated by JVM are:

 1. ClassLoader: It is a component of JVM used to load class files.

 2. Class (Method) Area: It stores per-class structures such as the runtime constant pool, field and method data, and the code for methods.

 3. Heap: Heap is created a runtime and it contains the runtime data area in which objects are allocated.

 4. Stack: Stack stores local variables and partial results at runtime. It also helps in method invocation and return value. Each thread creates a private JVM stack at the time of thread creation.

 5. Program Counter Register: This memory area contains the address of the Java virtual machine instruction that is currently being executed. 

6. Native Method Stack: This area is reserved for all the native methods used in the application.
