im是Java&的新功能android，我之前没有看到数据类型T[]，有人可以解释一下它是什么还是给我一些有关它的网页?

im new to java & android, i didn't see the data type T[] before, can anyone explain what it is or give me some web page about it?

推荐答案

T是一个具体的类类型(不太可能)，或者是一个通用类.查看您的班级标题，看看是否是这种情况.

The T is either a concrete class type (unlikely), or it is a class generic. Look at your class heading to see if this is the case.

IE

Class SomeClassType<T> {}

有关泛型及其工作原理的教程，请参见 http://docs.oracle.com/javase/tutorial/java/generics/index.html
