Java Syntax of SomeClass.class

Recently I have come across the following syntax in Android:

Intent i = new Intent(getApplicationContext(), SomeActivityClass.class);

Could someone please explain what happens when SomeActivityClass.class is called?

class is a static class field of each class, of type Class<?> which represents the type of that specific class. It is often used for instantiating a class by reflection (as in the intent case).

i.e. - after:

Class<?> clazz = SomeActivityClass.class;

clazz will refer to an object of type Class<?> that represents the SomeActivityClass class.

When the Intent is invoked, it starts the SomeActivityClass Activity the same as any other Activity. ie, calls onCreate(), then onStart(), etc.

Refer to the flowchart diagram in the Activity documentation here... http://developer.android.com/images/activity_lifecycle.png

Or see the Activity documentation here... http://developer.android.com/reference/android/app/Activity.html
