How does a '.class' property work?

Question

First time developing in Java, and first time developing for Android, so it\'s quite a newbie question.

I currently have this code:

public void onBt         


        

Answer 1

Instances of the class where Class represent classes and interfaces in a running Java application. This is part of java Reflection API. From Oracle tutorial:

If the type is available but there is no instance then it is possible to obtain a Class by appending ".class" to the name of the type. This is also the easiest way to obtain the Class for a primitive type.
