In summary,a class is loaded:

  • when the new bytecode is executed,eg. SomeClass sc = new SomeClass()
  • when the bytecodes make a static reference to a class,eg. System.out

A class is initialized when a symbol in the class is first used.When a class is loaded it is not initialized.JVM will initialize superclass and fields in textual order, initialize static,final fields first, and give every field a default value before initialization.
