Load: Query and import binary data of classes or interfaces;
Link: perform the following verification, preparation, and resolution steps. The resolution steps are optional;
Verify: Check whether the binary data of the import class or interface is correct;
Preparation: allocate and initialize the storage space for static variables of the class;
Resolution: convert a symbolic reference to a direct reference;
Initialization: activates static variables of the class, and initializes Java code and static Java code blocks.
