Yes , non abstract method can access abstract method , but this abstract method will be implemented in its subclass and the same will be invoked from the non abstarct method of abstract super class. if not implemented the subclass must also be an abstract class. so doesn't create any issue. Instance can't be created for the same . Source: CoolInterview.com

{


abstract int hello();


int hai()
{
hello();
return 1;
}
}
