This is my note of reading JVM specification. I draw a diagram which helps me understand.

1. Data Areas for Each Individual Thread (not shared)

Data Areas for each individual thread include program counter register, JVM Stack, and Native Method Stack. They are all created when a new thread is created.

Program Counter Register: it is used to control each execution of each thread.
 
JVM Stack: It contains frames which is demonstrated in the diagram below.

Native Method Stack: it is used to support native methods, i.e., non-Java language methods.  

2. Data Areas Shared by All Threads

All threads share Heap and Method Area.

Heap: it is the area that we most frequently deal with. It stores
arrays and objects, created when JVM starts up. Garbage Collection works
in this area.

Method Area: it stores run-time constant pool, field and method data, and methods and constructors code。 

Runtime Constant Pool: It is a per-class or per-interface run-time
representation of the constant_pool table in a class file. It contains
several kinds of constants, ranging from numeric literals known at
compile-time to method and field references that must be resolved at
run-time.

Stack contains Frames, and a frame is pushed to the stack when a
method is invoked. A frame contains local variable array, Operand Stack,
Reference to Constant Pool.

For more information, please go to the offical JVM specification site.
