第二章 一切都是對象

包名為什麼要大寫？

                 
和OS有關，在Unix系統下A和a分別代表兩個目錄（同一根路徑下），而在windows  下是一個目錄。

執行new來創建對象時，數據存儲空間才被分配，其方法才供外界調用。

 

Static修飾的變量和方法，被稱為類數據和類方法，代表那些數據和方法只是作為整個類，而不是類的某個特定對象而存在的。

 

所有的javadoc命令都只能在“/**”註釋中出現，註釋結束於“*/”。

javadoc只能為public和protected成員進行文檔註釋。Privatet和包內可訪問成員的註釋會被忽略。

在java SE5中，javadoc標籤@deprecated標籤已經被@Deprecated註解所替代。
注：warning - Tag @version cannot be used in method
documentation.  It can only be used in
the fol
4000
lowing types of documentation: overview, package, class/interface.
warning - Tag @author cannot be used in method
documentation.  It can only be used in
the following types of documentation: overview, package, class/interface.
