what block of code

In this section we look at a more specific concept, which is static code blocks.We've also mentioned code blocks before, which is a separate code space. So what is a static block of code? To put it bluntly, it is a code block decorated with

synchronized keyword, which consists of two usages:synchronized method and synchronized block 1. Synchronized method: Declares the Synchronized method by adding the Synchronized keyword to the method declaration. such as:   public synchronized

Execution order: Priority from high-Low: Static code block-"Main method-" Construction code block-"construction method.1, ordinary code block. (can be executed sequentially)2, constructs the code block. (a block of code that is defined directly in a

The storage period is the life cycle --the time that the variable is kept in memoryThe scope of the variable and the link together indicate which parts of the program can be used by the variable name.Note: Lifetimes and scopes are two different

Thread SafetyThe core of writing thread-safe code is to manage state access operations, especially access to shared and mutable states.The state of an object refers to the data stored in a state variable, such as an instance or a static domain. the

The most basic requirement for program robustness is the processing and capturing of program errors. in ASP. NET, the error processing mechanism is the same as that in other programming languages. You can use Try... Catch... Finally and so on, which

1//Common 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--"first occurs first" 2

One, thread safety issues:The principle of concurrent programming: The purpose of designing concurrent programming is to make the program achieve higher execution efficiency, but there must be no data consistency (data accurate) problem, if the

Hosting vs. native threadingManaged code executes on a "managed thread" (managed thread) that differs from the native thread that the operating system provides. A native thread is a sequence of native code that executes on a physical machine, while
