Background:Just when I saw the volatile modifier, I read that the author was reading the Java language Specification and then translated it into his own understanding.Survey:Java language Specification, the Java

as the programming format specification of Hebei post application system software (Java language). In the process of coding, testing and maintenance of the system, strict compliance is required.3. Java Naming conventions3.1 Public engagements naming refers to the name of the source file name, method, directory, packag

Code | Specification 1 Introduction (Introduction) 1.1 Why should there be coding specifications Coding specifications are particularly important for programmers for a number of reasons: -80% of the cost of a software lifecycle is to maintain -Almost no software, throughout its lifecycle, is maintained by the original developer -Coding specifications can improve the readability of the software, allowing programmers to understand the new code as quick

The Java language specification requires the Equals method to have the following characteristics:(1) Reflexivity: For any non-null reference x,x.equals (x) should return true;(2) Symmetry: For any reference to x, and Y, if and only if, Y.equals (x) returns True,x.equals (Y) should also return true;(3) Transitivity: For any reference to X, Y, Z, if X.equals (y) re

Note: According to the Java language Specification, the main method must be declared public.Some versions of the Java interpreter can also execute Java applications when the main method is not public. One of the programmers reported the bug. If interested, check this bug num

improve the readability and extensibility of the program6. The method should not exceed 2 layers of the circulating cover7. For classes that do not require subclasses to overload during design time, use the final8. Try to avoid more than 100 lines of code per method (valid lines of code, not including comments), but must ensure the integrity of the logic9. The method in the interface defaults to protected, exposing the method to public only if it is confirmed that the package of the other subsy

whether it is final. The 7) class member method is only intended for internal invocation of the class and must be private. The 8) class member method is only exposed to the inheriting class, and is limited to protected. description: Any class, method, parameter, variable, strict access to the scope. A wide range of access is not conducive to module decoupling. Think test: If it is a private method, you want to delete it, but a public service method, or a The scope of the variable

for readability, as the following description contains indents:/** * Here are a method comment with some very special* formatting that I want indent (1) to ignore.* */Method annotations generally include:1. The main description of the method, in. Or. End2. Describe how the method accomplishes the purpose of the method, and the reason for using the method3. Describe how the method is used, including the environmental requirements used, such as preconditions, post conditions, and concurrency requ

Java object model specification and Object Model SpecificationThe following is a set of object model (entity model)-vo (Object model that interacts with the front-end) that I have summarized based on my work experience, frontend refers to pages, mobile terminals, and remote service calls.)-xxxReq (the entity corresponding to the json request sent by the frontend)-xxxResp (the entity corresponding to the res

One of the most important features of. NET is cross-language programming, and DLLs written in C # can be called in vb.net, for example:A class written in C #, compiled into a DLL, and then called in vb.net:Using System;Namespace Clssample{public class Clstest{Public Clstest (){}public void ABC (){Console.WriteLine ("ABC");}}}Called in vb.net:Dim C as Clssample.clstest = New clssample.clstestC.ABC ()Now add a function to the Clstest class in the DLL:pu

The JavaScript programming language, as the most popular client-side scripting language, has long been known to many WEB developers. With the advent of the Web2.0 era and the wide application of Ajax technology, JavaScript has gradually attracted more attention.
