yes,its possible.We can write an abstract class without any concrete methods,There is no restriction that the abstract class contains minimum of one abstract method.Eventhough without any abstract method we can write the abstract class.

Your statement is almost correct but..every abstract class need not contain abstract methods..means if one class does n't contain any abstract methods then also we can declare class as abstract..but if the class contains any abstract method then that class should be declare as abstract.
