 UUID 
     關於UUID，我們需要知道它最重要的一點，就是它會生成全地球唯一的一個id，它可以作為資料庫的主鍵存在，標識各個元組。 UUID保證對在同一時空中的所有機器都是唯一的，利用機器的當前日期和時間、時鐘序列、全域性唯一的IEEE機 

  
 

    

    
    Java原始碼分析——java.util工具包解析（四）——四大引用型別以及WeakHashMap類解析
       
 
  
  
     WeakHashMap是Map的一種很獨特的實現，從它的名字可以看出，它是存貯弱引用的對映的，先來複習一下Java中的四大引用型別： 
  
  強引用：我們使用的大部分引用實際上都是強引用，這是使用最普遍的引用。強引用的物件垃圾回收器絕不

     Map，中文名字對映，它儲存了鍵-值對的一對一的關係形式，並用雜湊值來作為存貯的索引依據，在查詢、插入以及刪除時的時間複雜度都為O(1)，是一種在程式中用的最多的幾種資料結構。Java在java.util工具包中實現了Map介面，來作為各大 

  
 

    

    
    Java原始碼分析——java.util工具包解析（二）——HashSet、TreeSet、LinkedHashSet類解析
       
 
  
  
     Set，即集合，與數學上的定義一樣，集合具有三個特點： 
  
  無序性：一個集合中，每個元素的地位都是相同的，元素之間是無序的。 
  互異性：一個集合中，任何兩個元素都認為是不相同的，即每個元素只能出現一次。 
  確定性：給定一個集

    Java中的包掃描（工具）
      在現在好多應用場景中，我們需要得到某個包名下面所有的類， 包括我們自己在src裡寫的java類和一些第三方提供的jar包裡的類，那麼怎麼來實現呢？ 
 今天帶大家來完成這件事。

    Java原始碼分析——java.lang.reflect反射包解析(三)　動態代理、Proxy類、WeakCache類
       
 
  
  
     代理模式是一個經常被各種框架使用的模式，比如Spring AOP、Mybatis中就經常用到，當一個類訪問另外一個類困難時，可通過一個代理類來間接訪問，在Java中，為了保證程式的簡單性，代理類與目標類需要實現相同的介面。也就是說代理模式起 

  
 

    

    
    Java原始碼分析——java.lang.reflect反射包解析(二)　Array類，陣列的建立
       
 
  
  
     在Java中，引用型別中有那麼幾個特殊的類，Object類是所有類的起源、Class類定義所有類的抽象與行為、ClassLoader類實現了類從.class檔案中載入進jvm，而Array陣列類，則實現了陣列手動的建立。

    Java原始碼分析——java.lang.reflect反射包解析(一)　AccessibleObject、ReflectionFactory、Filed、Method、Constructor類
       
 
  
  
     Java的反射機制一直是被人稱讚的，它的定義是：程式在執行中時，對於任意一個類，都能夠知道這個類的所有屬性和方法；對於任意一個物件，都能夠呼叫它的任意一個方法和屬性。簡單的來說就是可以通過Java的反射機制知道自己想知道的類的一切資訊。

 wxml工具 ## 現在為大家介紹個自己製作的xml解析工具：wxml。這塊工具可以自動的將xml和java類進行相互的轉換， 
   整個過程可能只需要1-2行程式碼。當然jaxb也是可以完成這樣的功能的，不過我個人認為我的工具更簡單些。不說這麼多，看程式碼。
