The Runtime is not an abstract class..! abstract means incomplete class..! and it is not necessary that abstract class should have atleast one abstract method.

Since, the methods in Runtime class like, gc, totalmemory...are
native methods..not abstract methods..means the implementation will be in c++/c format.
