Introduction??This chapter is about the memory area of the Java virtual machine can be divided into several parts, the book can be divided into five parts: heap, Stack, program counter, method area, local method stack??Where the heap contains an instance of the object??And often said the basic data type, and the object reference is stored in the stack, in fact, is actually stored in the

0. Preface Java virtual machines, like real computers, perform binary machine codes, and we compile. Java source code into a. class file, and the class file is the binary machine code that the Java virtual machine can recognize. Java can recognize the information and

??This phrase feels like the nature of the GC .??????1. Procedure Counter (program Counter Register)??A program counter is a small amount of memory space that acts as a line number indicator of the bytecode that is being executed by the current thread . The bytecode interpreter works by changing the value of this counter to select the next byte-code instruction to execute, and the basic functions such as branching, looping, jumping, exception handling, thread recovery, and so on, need to rely on

Preface System migration refers to moving the operating system and applications on the source host to the target host and running properly on the target host. In the era when there is no virtual machine, the migration between physical machines relies on system backup and recovery technologies. Back up the operating system and application status on the source host in real time, connect the storage media to t
