Java class loading process: The first is the loading process, which is to read the bytecode data from different data sources into the JVM virtual machine; then the connection, which is the core step, simply put the original class definition information smoothly Enter the process of JVM running; the last step is initialization.

1. The class loading process loads the fully qualified name of the class (package name + class name), obtains the .class file of the class, and loads it into the metaspace. Link verification: Verify the security of the .class file. Preparation: Allocate memory for static type variables and set default values. Resolution: Convert symbol references in the constant pool into direct references. The symbol references point to an unloaded class, or an unloaded class. field or method, then the parsing will trigger the process of loading, initializing and executing the constructor method init() of the class. If the class has a parent class, jvm will ensure that the init of the parent class is executed first, and then the init of the subclass is executed. . 2.

PHP has a complete reflection API, providing the ability to reverse engineer classes, interfaces, functions, methods and extensions. Through the capabilities provided by class reflection, we can know how the class is defined, what attributes it has, what methods it has, what parameters the method has, what the path to the class file is, and other very important information. It is also because of the reflection of classes that many PHP frameworks can implement dependency injection to automatically resolve the dependencies between classes, which brings great convenience to our daily development.
