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
Java Object creation Process: the creation of the object begins :Virtual opportunity to the New keyword, first go to the constant pool to find out if there is no symbolic reference to this class, and check whether the referenced class has been loaded, parsed, and initialized, if not, the class will first execute the loading process, after passing the check, the virt
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:

As mentioned above, the loading mechanism of the class, which refers to the initialization of the class using a part of memory management knowledge, here let us see how the Java Virtual Machine management memory.Let's take a look at the picture first.In some articles, the thread containment zone is also known as the thread exclusive area, which is actually a mean
Thread run data is differentiated into thread share and thread exclusive zoneThe thread exclusive zone means that each thread that is opened will have a thread exclusive zoneAs shown in the following:Program Counter:1) is a small memory space that can be seen as the line number indicator of the byte code executed by the current thread2) It is in the thread exclusive zone (each thread will have its own thread exclusive zone)3) If the thread executes a Java
