What is the difference between Class.forName()andClassLoader.loadClass()?
Both methods try to dynamically locate and load a java.lang.Classobject corresponding to a given class name. However, their behavior differs regarding whichjava.lang.ClassLoaderthey use for class loading and whether or not the resultingClassobject is initialized. -
Additionally,
Class.forName()’s common form initializes the loaded class. The visible effect of this is the execution of the class’s static initializers
as well as byte code corresponding to initialization expressions of all static fields (this process occurs recursively for
all the class’s superclasses). This differs fromClassLoader.loadClass()behavior, which delays initialization until the class is used for the first time. -
if it is important to process all such errors at a known point in code,
you should use aClass.forName()version that performs initialization.

[翻译]走出ClassLoader的迷宫 – 惨淡人生,平淡生活 – BlogJava

Current ClassLoader:當前類所屬的ClassLoader,在虛擬機中類之間引用,默認就是使用這個ClassLoader。另外,當你使用Class.forName(),
Class.getResource()這幾個不帶ClassLoader參數的方法是,默認同樣適用當前類的ClassLoader。你可以通過方法XX.class.GetClassLoader()獲取。 -
Thread Context ClassLoader,沒一個Thread有一個相關聯繫的Context ClassLoader(由native方法建立的除外),可以通過Thread.setContextClassLoader()方法設置。如果你沒有主動設置,Thread默認集成Parent Thread的 Context ClassLoader(注意,是parent Thread 不是父類)。如果 你整個應用中都沒有對此作任何處理,那麼 所有的Thread都會以System ClassLoader作為Context ClassLoader。知道這一點很重要,因為從web服務器,java企業服務器使用一些複雜而且精巧的ClassLoader結構去實現諸如JNDI、線程池和熱部署等功能以來,這種簡單的情況越發的少見了。

Lockobjects work very much like the implicit
locks used by synchronized code. -
As with implicit locks, only one
thread can own aLockobject at a time.
