java class static initialization

When we look at the implementation of Android ContentProvider today, I suddenly think of the Java class in the process of new, static domain, static block, non-static domain, non-static block, constructor execution order problem.

Class B extends A, then the type a is the parent class with static code blocks, common code blocks, static methods, static member variables, ordinary member variables, common methods.Subclasses are also like this, and then inherit the results about the printout of the progra

The order of data initialization in a class is one of the questions that the interviewer likes very much, this article uses an example to introduce the Java sub-class, the parent class static code block, the field, the non-

, initialization blocks, and constructors are initialized.What about the sequence between static and static initialization blocks, variables, and initialization blocks? Is the static variable always initialized before the

Article Author: TyanBlog: noahsnail.com | CSDN | Jane book 1. Initialization in Java One difference between Java and C + + is that Java has not only constructors, but also an "initialization block" (initialization blocks) concept.

Class. forName () + Class. forName (). newlnstance () and the relationship between the new statement and the initialization block + static initialization block + constructor, Code first Class A {int a;

C + + classes have several types of data members: normal type, constant (const), static (static), and static Const. Here are the following ways of initializing them before and after c++11 respectively.Initialization of previous versions of C++11Before c++11, regular data member variables can only be initialized in constructors and

opportunity. But when the new thread executes and outputs the website value, because the staticthreadinit class has not been initialized, the new thread has to give up the execution. The thread scheduler switches to the main thread again, and the mian thread completes website initialization. So far, the staticthreadinit class

Static initialization is performed only once, and instance initialization is performed every time the instance is created.1. Create a spoon class: Package com.samsung.wx; Public class Spoon { System.out.println ("Static
