Java Class Execution order

When a class starts from being loaded by the JVM, the execution order of the various codes is roughly the following:

Dependent code of the executing parent class, which is loaded by the JVM, if there is static initialization, perform static initialization first, and execute only once, and then even if there is a static code block that executes in the same way as static initialization. If there is an instantiation of the new statement, allocate space for the member variable, bind the argument list, implicitly or explicitly execute super (), that is, the construction method of the parent class,-> execute the non-static code block-〉 execute the constructor of this class-〉 execute other code
