Class类型

Class类（在java.lang包中，Instances of the class Classrepresent classes and interfaces in a running Javaapplication）：

在Java中，每个class都有一个相应的Class对象。也就是说，当我们编写一个类，编译完成后，在生成的.class文件中，就会产生一个Class对象，用于表示这个类的类型信息

 

public final Class<?> getClass ()

Added in API level 1

Returns the unique instance of Class that represents this object's class. Note that getClass() is a special case in that it actually returns Class<? extends Foo> where Foo is the erasure of the type of the expression getClass() was called upon.

As an example, the following code actually compiles, although one might think it shouldn't:

List l = new ArrayList(); 
   Class<? extends List> c = l.getClass();

Returns

• this object's Class instance.
