Class Loader ClassLoader

class loader working mechanism

The ClassLoader is looking for a bytecode file for a class and constructs an object component that the class represents within the JVM. In Java, the ClassLoader loads a class into the JVM and takes the following steps

1. Loading: Finding and Importing class files
2. Link: Perform the validation, preparation, and resolution steps, where the resolution step is optional
   • Checksum: Check the correctness of loading class file data
   • Preparing: Allocating storage space for static variables of a class
   • Parsing: Turning a symbolic reference into a direct reference
3. Initialization: Initialization of static variables and static blocks of code for a class
