在Java中使用class关键字 [英] Working with the class keyword in Java

问题描述

我不太明白 class 关键字在某些情况下是如何工作的。

I don't really understand how the class keywords work in some instances.

get（ClientResponse.class）方法接受 ClientResponse.class 。当它获取它时如何使用它，和只是传递一个实例的优点是什么？

For example, the get(ClientResponse.class) method takes the ClientResponse.class. How does it use this when it gets it, and what are the advantages over just passing an instance of it?

推荐答案

SomeClass.class

返回Java类对象。类是泛化的，因此SomeClass.class的实际类型将为 Class< SomeType> 。

returns a Java Class object. Class is genericized, so the actual type of SomeClass.class will be Class<SomeType> .

此对象的用途，您可以在这里阅读Javadoc： http： //docs.oracle.com/javase/6/docs/api/java/lang/Class.html

There are lots of uses for this object, and you can read the Javadoc for it here: http://docs.oracle.com/javase/6/docs/api/java/lang/Class.html
