Hi Suresh,
Refer to the below link and it has captured similar information as posted above.
But these links have hyperlinks to other class details/clarification which will give you more insight on those as well.

The above question is basic of OOPS.
Abstract Class :- Abstract Class can not be instatiated (It does not create Object to be Stored in DB), In Pega we Use "-"as suffix of Class Name (Naming covention we follow to identify Abstract Class) For ex : Comp-CompFW-
Concrete Class :- The class whihc we can Instantiate (Can be used to create Objects and saved into DB).
Hi Suresh,
An abstract class is a rule (an instance of the Rule-Obj-Class class) created to support the definition of rules, including other classes. Such rules can be inherited by subclasses of the abstract class. Rules with a class as a key part (such as properties, activities, flows, data transforms, and so on) can apply to an abstract class.
A class that is not abstract is concrete. Unlike abstract classes, concrete classes can have instances stored in the database. A selection on the Class rule form determines whether a new class is abstract or concrete.
An abstract class can be a child of a higher abstract class.
A selection on the Class form determines whether a class is concrete or abstract.
Concrete classes usually appear near or at the bottom (leaf nodes) of the class hierarchy, but may appear anywhere below the top level.
Hope this helps!
