代碼說(shuō)明文檔java 代碼說(shuō)明文檔app

java項(xiàng)目 代碼結(jié)構(gòu)說(shuō)明書(shū)怎么寫(xiě)

接口文檔，代碼層次（比如公共方法寫(xiě)在哪個(gè)class里），哪些為一大類(lèi)在一個(gè)包下，數(shù)據(jù)字典，就是介紹你這個(gè)項(xiàng)目的架構(gòu)讓后來(lái)的人怎么能容易參與開(kāi)發(fā)，交接什么看這個(gè)就可以方便些，輔助作用的一個(gè)文檔一般都是項(xiàng)目經(jīng)理寫(xiě)

我們提供的服務(wù)有：成都網(wǎng)站設(shè)計(jì)、成都網(wǎng)站建設(shè)、微信公眾號(hào)開(kāi)發(fā)、網(wǎng)站優(yōu)化、網(wǎng)站認(rèn)證、祥云ssl等。為上1000家企事業(yè)單位解決了網(wǎng)站和推廣的問(wèn)題。提供周到的售前咨詢和貼心的售后服務(wù)，是有科學(xué)管理、有技術(shù)的祥云網(wǎng)站制作公司

java中說(shuō)明書(shū)/開(kāi)發(fā)文檔如何編寫(xiě)

由于在java開(kāi)發(fā)時(shí)我們得到的或者給別人的文件一般都是class文件，不會(huì)給出源文件，故編寫(xiě)一個(gè)簡(jiǎn)潔易懂的說(shuō)明書(shū)是必須的。

ps：?@param int[] arr 會(huì)有警告，可以刪掉 int []。

用工具解析文檔注釋?zhuān)簀avadoc工具

javadoc -d 目錄 -d -author ?-version ArrayTool.java

有時(shí)會(huì)提示出錯(cuò)：找不到可以文檔化的公共或受保護(hù)的類(lèi)--在class前加一個(gè)public即可。

我想要一個(gè)JAVA邊的計(jì)算器的原碼并有代碼說(shuō)明文檔
