One: Ordinary code block1 //Ordinary code block: {} that appears in a method or statement is called a normal code block . ordinary blocks of code and general execution order of statements are determined by the order in which they appear in the code-"
121, what is a thread? A thread is the smallest unit that the operating system can perform operations on, which is included in the process and is the actual operating unit of the process. Programmers can use it for multiprocessor programming, and
Order of execution: (priority is from high to low.) )
Static code block >mian method > Construction Code block > Construction method.
Where the static code block is executed only once. The construction code block executes every time the object is

Awk is suitable for text processing and report generation, and it has a number of well-designed features that allow you to program programs that require special skills.awk syntax is more common. It draws on some of the best
On a basic level, it is important to understand how JavaScript timers work. The execution of timers is often different from our intuitive imagination, because the JavaScript engine is single-threaded. Let's start by recognizing how the following
The Java language keyword synchronized, when used to decorate a method or a block of code, guarantees that at most one thread executes the code at the same time.
First, when two concurrent threads access the same object in the synchronized (this)

If the table is updated or inserted into the operation, it will go through a unified file, this way is a multi-process concurrency can be resolved problem;
Here's how it's implemented:
public static function Cbinventoryreserve () {
Lang_name Code do executes an anonymous block of code, in other words, an anonymous function that executes once in a program language.A block of code is considered a function body with no parameters, and the return value type is void. Its parsing
The Java language keyword that, when used to decorate a method or a block of code, guarantees that at most one thread executes the code at the same time.
1. When two concurrent threads access the synchronized (this) synchronization

The first chapter Java Multithreading Skills 1, the implementation of multi-threaded way: One is to inherit the thread class, the other is to implement the Runnable interface. The difference between the two is that the essence of inheriting
Original: http://www.2ality.com/2012/01/object-plus-object.htmlGary Bernhardt recently pointed out an interesting JavaScript quirk in a short lecture video "Wat" : When you add objects and arrays together, you get some unexpected results. This
The sixth chapter is familiar with the Java Process Control statementJava Program flow control is divided into sequential structure , selection structure , loop structure and jump statements .

One, the Python statementPython statements are broadly divided into: sequential execution statements, conditional execution statements, loop execution statements.Statements run individuallyPython executes statements from a nested block in a file
If we have embedded in the HTML as JS block of code (in fact, JS does not have a block of code meaning, if really want to think of code block that also should be divided by function block), Here is the JS Code execution order: Here reproduced JS

Timer is a good thing, but many people only know its syntax, lack of understanding of its principles. The timer asynchronously executes a piece of code by setting a certain period of time (in milliseconds. Because Javascript is a single-threaded
