public abstract class AAA
{
// Nothing inside
}
This compiles absolutely fine.
Found a list of Abstract Class FAQ:
- Must abstract classes contain at least one abstract method?
- Can a static method be abstract?
- Why can’t an abstract method be declared private?
Q:How can I declare a constructor for an abstract class?

An abstract class is simple a class which cant be instantiated.
An abstract method defined within an abstract class must be implemented by all of its subclass.
Abstract method cannot be instantiated,it is generally used for inherited.

1. A class containing atleast one abstract method is called an abstract class.

2. A class may be declared abstract even if it has no abstract methods.
