Preface If someone asks you what the memory area of Java is divided into, many people might say: heap, stack, method area .... I personally understand that Java can relate to the "memory Area" from the developer's point of view in two ways: First, the Java Virtual Runtime data area, and the second,
1. Program Counter: is a small memory space that can be viewed as a line number indicator executed by the current thread, and the byte code parser, when working, selects the next byte-code instruction that needs to be executed by the value of the variable program counter. The basic functions of a program's branch-loop jump, exception handling, and thread recovery are all dependent program counters. Java Virtual

Program Counter Register: A small amount of memory space that can be seen as the line number indicator of the byte code executed by the current thread. The bytecode interpreter works by changing the value of this counter to select the next byte-code instruction that needs to be executed, such as branching, looping, jumping, exception handling, thread recovery, and other basic functions that rely on this counter to complete. The multithreading of the Java

Preface Recently found that sometimes after reading a book, time is easy to forget, reading does not summarize the effect of a large discount, it is intended to write this series of articles, one is to tidy up the main points in the book, to help their digestion and understanding; the second is to encourage themselves to read more thinking. The article will not explain the contents of the book is very detailed, but summed up, suitable for the reader has read the book. 2nd Chapter:
