Reference: http://uule.iteye.com/blog/1558891Static code blocks in Java are executed when the virtual machine loads the class, and only once. If there are multiple static blocks of code, the JVM executes them sequentially in the order in which they appear in the class, and each code block is executed only once.A non-static block of code is executed at the time of the class new instance, and every time a new

In Java and Android, what is the difference between the execution order of blocks of code and static code blocks?JavaLet's start with a simple example.Main.java:publicclass Main { staticint1; static { System.out.println(a); } static { 2; } publicstaticvoidmain(String[] args) { System.out.println("Hello World!"); System.out.println(a); }}Output to 1He

Building blocks: Code blocks that are written directly in a classStatic code collapse: blocks of code declared with the static keywordStatic code blocks are constructed before the construction block, and are executed only once when the class is loaded, and later when the class is instantiated, the building

Three cases: Interpreting static code blocks and constructing code blocks. I. Summary of static and non-static code blocks 1. Static code block: Static code blocks are called first when a class is loaded (memory) and executed once. Static code blocks are often used to initia

Oracle tablespaces (tablespace), segments (segment), disk partitions (extent), and blocks are the allocation units used by Oracle to save database objects. A segment is a database object that consumes storage space, such as tables, indexes, and rollback segments. When you create a table, a table segment is created. When you create a partition table, a segment is created for each partition. When you create an index, an index segment is created, object

The execution sequence of static blocks, main methods, constructor blocks, and constructor methods. If you encounter a problem with the execution sequence of static blocks, main methods, constructor blocks, and constructor methods, add this note. The question is the order in which the following java code is printed a

Fully conforms to the creation process described above.The following test loads the parent class and then creates the subclass object directly. Public class initobjecttest{ publicstaticvoid main (string[] args) { Try{ //class.forname ("Parent"); Class.forName ("Parent"); Catch (Exception e) { } System.out.println ("=============== now, we create a Object below ==

JQuery blocks event bubbling instance code. jquery blocks bubble instances. JQuery prevents event bubbling instance code:The definition of event bubbling is not described here. For details, refer to the section about jquery event bubbling. The following is a code example to block event bubbling. You can refer to it directly. The Code is as follows: The above code can prevent event bubbles. The code is ve

Differences between 1.java and C # static member invocationStatic, which is a shared resource, is created when the class is loaded.Java can be invoked through an instance, or by a class name. member name, but it is generally preferable to use the class name. Member this way, because static members belong to the class, not to specific objectsC # can only be called by the class name. Member, and cannot beTo invoke with an instance2.c# Static constructors and construction code

In a recent review of some of the knowledge in Java, here is a way to learn about static blocks of code and construct blocks of code.First of all, the code is balabala some definitions Ah, assignment Ah, the operation of some Java code, surrounded by two curly braces, it becomes a magic block of code{ a=3;} static{ b=4;}Just like the one above.The parentheses add static to the code block, you

Before starting this blog writing, please look at a classic Java face questionpublic class statictest{ public static void Main (String args[]) { Staticfunction (); } static Statictest st = new Statictest (); static{ System.out.println ("1"); } Statictest () { System.out.println ("3"); System.out.println ("a=" +a+ "b=" +b); } public static void Staticfunction () { System.out.println ("4"); } { System.out.println ("2"); }

Java static code blocks, construction code blocks, execution order of construction methodsstatic code takes precedence over non-static code because members that are modified by static are members of a class and are executed as the JVM loads the class, while members that are not statically decorated are also called instance members, and need to create objects to be loaded into heap memory. So static will tak
