Course Introduction: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. Class loader startup class loader startup class loader is implemented in C/C++ language and is used to load Java core classes

Course Introduction:Category 1. Boot class loader, written in C++, is the class loader that comes with the JVM and is responsible for the core library of the Java platform and is used to load the core class library. Construct ExtClassLoader and AppClassLoader. The loader cannot directly obtain the Java platform core library: jre\lib\rt.jar. Open it with compression software. The classes inside are what we usually learn. This jre is a public jre, not a dedicated jre2 or extended class loader in the jdk directory. It is responsible for putting the jar packages in the jre\lib\ext directory or the jar packages in the directory specified by -Djava.ext.dirs into the work library. Here is the jre as well. Public jre3, system class loader is responsible for j

Course Introduction:How to solve class loader conflicts in Java development Introduction: In Java development, class loader conflicts are a common problem. When different class loaders are used to load the same class or resource file, conflicts will occur, causing the program to fail to run properly. This article explains what a class loader conflict is and how to resolve it. 1. What is a class loader conflict? The class loading mechanism in Java adopts the parent delegation model. Each class loader has a parent class loader, and the final parent class loader is the startup class loader. when needed
