A scientific "abstract" is merely a summary of the study conducted while "explorative strategy" is a method used in scientific study. Whether or not this strategy is used the definition of "abstract" in the scientific sense remains the same. See examples of abstracts for explorative strategy studies at links below.
Yes, a class can be defined as final and abstract also.
The term interface class does not exist in C#. If this is a term describing a class being an interface to other component (human, subsystems, etc), it is very application specific. The designer of that application should know the abstraction.However, C# does have another type called interface. An interface is NOT a class. An interface defines the intention of some behaviors that classes may be extended it and provides the implementation. The intention, is nothing but method signatures, which defines the return data type, the method name, and any method arguments and associated data type. The implementation is the code of the method. Interface is used for separating the concern of design and implementation.Abstract class is a class with abstract keyword. It can be just like a class without that keyword (then, why it is an abstract class?). But it may have some methods or properties defined as abstract. These abstract methods, like the method signatures of an interface, defines the intention.The subclasses of such an abstract class would need to implement those abstract methods (providing the code).There are more common, differences between interfaces and abstract classes, please see answer(s) of those related questions in C# category.
The noun forms for the verb to define are difinability, definement, and the gerund, defining. Another noun form is definition.

Abstract terms can be difficult to define because they often represent complex ideas or concepts that do not have a clear, concrete representation. Since abstract terms can vary in meaning depending on context or individual interpretation, defining them in a precise and universally accepted manner can be challenging. Additionally, abstract concepts may be subjective and open to different perspectives, making them more elusive to pin down in a concise definition.
Abstract art is art that does not attempt to represent an accurate depiction of a visual reality but instead use shapes, colours, forms and gestural marks to achieve its effect.
because it involves only an abstract idea, not a material object.
Through the use of interfaces and abstract classes that define common behaviors
An abstract in java is used to specify that the class/function is not yet complete. When a class in declared as abstract it means that it is not meant to be instantiated (you can't create variables of that type). This is because they are meant to be more of a guideline for other classes. When a class extends an abstract class it must either define all of the abstract methods from the abstract class or it must also be declared as an abstract class itself.
Abstract painting is a type of art that does not attempt to depict an accurate representation of a visual reality, instead relying on shapes, colours, forms, and gestural marks to achieve its effect.
Abstract goals are broad and general objectives that are more conceptual and less specific in nature. They typically lack precise details or measurable outcomes, making them more challenging to define and achieve compared to concrete goals. Examples of abstract goals include happiness, success, and personal growth.
You would use an abstract class when you want a number of classes to have a similar functionality/methods list. The abstract class will have only method declarations and no definitions. So any class that extends this abstract class would have to provide the method definitions. This way you can ensure that all these classes will have a similar set of methods/features. This type of usage of an abstract class is similar to interfaces.
