Since the work above, the program because the code more write more, become more and more bloated, the efficiency will become lower, so I always like to constantly optimize the program structure outside, memory optimization and performance tuning.To
In-depth understanding of Java Virtual Machines: The process of class loadingClass starts from being loaded into the virtual machine's memory, and its entire lifecycle includes: load, validate, prepare, parse, initialize, use, and unload seven

What does {code...} mean? In my experiment, I understand that a non-qualified name means that no prefix is added when calling functionclass $, that is, the class or $ or function in the file where the code is located. Is that correct?

1. Overview
A class file is a group of 8-byte binary streams. Each data item is arranged strictly in a sequential and compact manner in the class file without any separators, this makes almost all the content stored in the entire class file
virtual machine class loading mechanismThe virtual machine loads the data of the described class from the class file into memory, verifies the data, transforms parsing and initializing, and finally forms the Java type that can be used directly by
Before using namespace for autoloading to introduce PSR-0, let's talk about NameSpace and Autoloading.
