This standard defines how your code should be styled for assignments and projects while studying here in the department. By following these conventions, you will produce code which is more readable and easier for you or someone else to follow. These guidelines apply to all programming languages. The examples are shown in Java. Being able to write clean legible code will also improve your employability.IdentifiersVariables/AttributesIdentifiers for all attributes and variables should be meaningful and if appropriate contain its own unit of measure. The unit of measure helps in understanding how to use it without reading the comments. Variables/attributes should always start with a lower case letter. Always use camel caseto help aid reading of identifies, so an upper-case letter is introduced for every new word.Examples:floatweightInKilos;floatheightInMetres;floatdelayInMilliseconds;Class IdentifiersClass identifiers always start with an uppercase letter and should always be a noun. So, Encryption is not a good name but Encryptor or EncryptionHelper are fine.Examples:PersonDoctorAppointmentConstantsIdentifiers of constants should always be expressed in uppercase, unless and only unless there is a necessary convention to use lowercase (for example to distinguish between g (ac-celeration due to earth’s gravity and G the universal gravitational constant). For constants underscores are used to separate words.Examples:publicstaticfinalfloatPI=3.149265445;publicstaticfinalintCOLUMNS=10;Method NamesMethod names should start with a lower case letter and then follow camel case. All method names should be verbs.Examples:publicstaticintadd(inta,intb)publicstaticintcheckTwoEqual(int[]array) CommentsThe code should ideally be what is termed self-documenting, that is it is simple enough to understand without keeping on referring to the comments. If the code is hard to follow then it should be simplified and in some cases broken up.Comments must always precede the part of the code that they refer to. Comments should not go over the right hand side of the edit window. If a comment is too long, then it should be broken down over several lines.JavadocAll comments in Java programs should follow the Javadoc format, this allows code docu-mentation to be generated automatically.Class CommentsAll classes should start with a preamble describing the purpose of the class, what data it stores and what services it provides, so that a user of the class can quickly determine how to use the said class.Method CommentsAt a minimum each public method in a class should be commented. This is vital since the public methods are the public interface to the code. Each method should have comment to both the input variables and the returned values (if there are any).Example:*Calculatesthefactorialofanumber*@paraminputNumbertobefactorialed*@returnFactorialofinputpublicFloatfactorial(intinput){/invalidnegativeinputif(input 0){return(Float.NaN);/intheremainderofthemethodthevalue/ofinputwillbegreaterorequalto0floatret=1;while(input 1){ret=ret*input;input--;return(newFloat(ret));}Use of On-line Resources and TextbooksIf in the preparation of your code you have used specific ideas or code fragments that you have found on-line or in a textbook, then you must include references to those source in your comments and indicate clearly which part of the code is based on those. The reference must be precise:•If you have used a textbook then you must point to the specific page, pages, or figure that you have used.•If you have used an answer to a question on, say, stackoverflow, then you must point to that specific answer, including a URL to that answer.Examples:/**ThecodeforthefollowingreadFilefunctionhasbeentakenfrom*erickson(http://stackoverflow.com/users/3474/erickson):*HowtocreateaJavaStringfromthecontentsorafile?*StackExchangeNetwork,16May2016.*http://stackoverflow.com/a/326440[accessed30October2017].*Usercontributionslicensedunderccby-sa3.0*https://creativecommons.org/licenses/by-sa/3.0/staticStringreadFile(Stringpath,Charsetencoding)throwsIOException{byte[]encoded=Files.readAllBytes(Paths.get(path));returnnewString(encoded,encoding);*ThecodeforthefollowingkeywordSearchfunctionhasbeentaken*fromFigure9.8onpage307of*R.MorelliandR.Walde:Java,Java,Java:Object-OrientedProblem*Solving(ThirdEdition).Pearson,2005.*Availableathttp://www.cs.trincoll.edu/~ram/jjj/jjj-os-20170625.pdf*[accessed30October2017]*underCreativeCommonsAttribution4.0InternationalLicense(CCBY4.0)*https://creativecommons.org/licenses/by/4.0/*Thevariablename ptr inthesourcehasbeenreplacedby pointer .publicStringkeywordSearch(Strings,Stringkeyword){StringresultStr= intcount=0;intpointer=s.indexOf(keyword);while(pointer!=1){++count;resultStr=resultStr+pointer+ pointer=s.indexOf(keyword,pointer+1);resultStr=count+ : +resultStr;returnresultStr;}Such attribution is required under the licenses that apply to the sources used in the examples as well as the Academic Integrity Policyof the University. Indentation and BracesAll code should be indented in a consistent way in order to correctly convey the program structure. The indentation should not be excessive otherwise the code become unwieldy and hard to read, so 3 white spaces is fine.The placing of braces should follow the one true brace style(1TBS): Constructs that allow insertions of new code lines are on separate lines, while constructs that prohibit insertions are on one line. Where it does not change the semantics, do use braces for a control statement with only a single statement in its scope.Examples:publicvoidevaluateBodyMassIndex(intbodyMassIndex){/Justonestatementinthescopeofthiscontrolstatement/butwestillusebracesif(bodyMassIndex =30){System.out.println( Thispatientisobese if(x 0){y=-1*Math.round(x*-1);}else{y=Math.round(x);}Note that for JavaScript there is a particularly good reason to follow 1TBS: JavaScript uses automatic semicolon insertion. For example, JavaScript adds a semicolon after return, if it is followed by a newline. This means the two statements in the example below have different meanings.Examples:/Thisreturnsanobjectliteralreturn{name: Jane /Thisisanemptyreturnstatementfollowedbyanobjectliteralreturnname: Jane }ConclusionFollowing this guidance will make your code easier to understand and follow and will help you debugging and maintaining your code.代写CS Finance|建模|代码|系统|报告|考试编程类：C++,JAVA ,数据库,WEB,Linux,Nodejs,JSP,Html,Prolog,Python,Haskell,hadoop算法,系统 机器学习金融类：统计，计量，风险投资，金融工程，R语言，Python语言，Matlab，建立模型，数据分析，数据处理服务类：Lab/Assignment/Project/Course/Qzui/Midterm/Final/Exam/Test帮助代写代考辅导E-mail:[email protected]微信：BadGeniuscs 工作时间：无休息工作日-早上8点到凌晨3点如果您用的手机请先保存二维码到手机里面，识别图中二维码。如果用电脑，直接掏出手机果断扫描。
