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. In fact, this is a very classic question, very much to examine the Java basic knowledge of the degree of mastery. A lot of the interview process is believed to have such a problem, while the weekend has time to review.Conclusion Let's put the finished conclusion to ever

1. Static code blocks are---initialized to the class, executed only once when the class is loaded (note: Only a reference to the class is created (that is, only the declaration) does not touch the load on that class)/** * Static code block * Features: Executes as the class is loaded, executes only once, and is used to initialize the class by rows */ static{ System.out.println ("a"); }2. (Display initialization block) constru

First, static blocks of code, construction blocks, and constructors all exist in a class, except that they perform in different order and execution times. A static block of code that executes only once, for example, when you want to create 10 objects, execute once when you create the first object, and then when you continue to create the remaining objects, the static code block is not executed. and the simi

Common code blocks in Java, building blocks of code, static code block differences, and code examplesThe static code block and the execution of the constructor sequence, has been very confused, read Sun Weichen teacher's "Java Object-oriented programming" and the teacher's Java basic Video in the explanation, now use the following small procedure to brief the narrative, in order to deepen understanding, and

The initialization Object Sequence in Java, the usage of Static code blocks, and the usage of Static code blocks (1) differences between static methods for java static code blocksGenerally, if some code must be executed when the project is started, a static code block is required. This code is actively executed and needs to be initialized when the project is started, when other programs call an object witho

Introduction: indexing hot blocks are actually very different from the hot blocks of data blocks. They are also caused by a large number of sessions accessing the same index block. Our solutions include reverse indexing, partition indexes. Let's talk about any one Introduction: indexing hot blocks are actually very dif

Summary: static code blocks are always executed first. A non-static block of code, like a non-static method, is related to an object. Only non-static blocks of code are executed before the constructor. A non-static block of code and a constructor for a subclass are only started when the parent class is non-static and the constructor finishes executing (equivalent to the initialization of the parent class ob
