什么是T []对象？(what's T[] object?)

什么是T []对象？(what's T[] object?)

ArrayAdapter的构造函数如下所示：

ArrayAdapter(Context context, int textViewResourceId, T[] objects)

即时通讯新的Java和Android，我没有看到数据类型T[]之前，任何人都可以解释它是什么，或给我一些关于它的网页？

the constructor of ArrayAdapter is as follows:

ArrayAdapter(Context context, int textViewResourceId, T[] objects)

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?

最满意答案

T是具体的类类型（不太可能），或者它是类通用的。 看看你的班级标题，看看是否是这种情况。

IE

Class SomeClassType<T> {}

有关泛型的教程及其工作原理可以在这里找到http://docs.oracle.com/javase/tutorial/java/generics/index.html

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> {}
