*"does it acquire space in class area"* What's a "class area"? – T.J. Crowder Sep 15 '16 at 09:42

1***sigh*** The point is that "class area" has no commonly-accepted meaning in the Java world. Say clearly what you're asking. – T.J. Crowder Sep 15 '16 at 09:46

Loading a class consumes memory, yes. (For instance, as you mention, in the method area, but not just there.) So does loading an interface (depending on whether it has default methods, it may or may not occupy any room in the method area, but it will consume memory. The class being abstract or not has no bearing whatsoever on the amount of space the class takes up when loaded. All abstract does is prevent you instantiating that class directly rather than as part of a subclass.
