Method area : This is logically a part heap space which will contain the class skeleton. It stores per class structures means run time constants and static variables, methods, constructors, class names and also class type information. It is a shared resource. Only one method area will reside in JVM. In Runtime constant pool string literals will be stored. Here literals don't relate to any object instances. Run time constant pool doesn't relate to object instances.
Heap: Here information about objects will be stored. If we create object in heap space will be allocated. If object dies then memory garbage collected. It is common space shared among all threads.
Stack area: It is not shared memory. Per every thread one run time stack will be created. It holds local variables, parameters, intermediate results and other data. It plays role in method invocation and return. JVM stores thread information in discrete frames. These frames will be stored in JVM stacks with push and pop operations. Here stack memory need not to be contiguous and it is dynamically expanded. If memory is not sufficient for expansion it will throw out of memory error.
PC register: whenever new thread is created then it will get pc register. Pc register will store the address of current instruction to be executed.
Native method stacks: native method stack will store native methods. This is also not a shared resource. Native method is java method but implementation will be another language mostly in c. these methods usually used to interface the system calls and libraries.
