8. Strategy : Although it is the first section of your paper, the Abstract, by definition, must be written last since it will summarize the paper. To begin composing your Abstract, take whole sentences or key phrases from each section and put them in a sequence which summarizes the paper. Then set about revising or adding words to make it all cohesive and clear. As you become more proficient you will most likely compose the Abstract from scratch.

Tutorial: Concrete vs. Abstract Thinking

Abstract class can consist of abstract methods as well as not abstract method So you can notice the difference in not necessarily every method your implementing class must only need to override the abstract methods.

Abstract - Dictionary of English

For sure it is important to understand the behaviour of interface and abstract class in OOP (and how languages handle them), but I think it is also important to understand what exactly each term mean. Can you imagine the if command not working exactly as the meaning of the term? Also, actually some languages are reducing even more the differences between interface and abstract. if by chance one day the two terms operate almost identically, at least you can define yourself where (and why) should any of them be used for.

Main difference is methods of a Java interface are implicitly abstract and cannot have implementations. A Java abstract class can have instance methods that implements a default behavior.

After all that, the interviewer came up with the question "What if you had an Abstract class with only abstract methods? How would that be different from an interface?" I didn't know the answer but I think it's the inheritance as mentioned above right?

The interviewers are barking up an odd tree. For languages like C# and Java, there is a difference, but in other languages like C++ there is not. OO theory doesn't differentiate the two, merely the syntax of language.

Now that the use of on-line publication databases is prevalent, writing a really good abstract has become even more important than it was a decade ago. Abstracts have always served the function of selling your work. But now, instead of merely convincing the reader to keep reading the rest of the attached paper, an abstract must convince the reader to leave the comfort of an office and go hunt down a copy of the article from a library (or worse, obtain one after a long wait through inter-library loan). In a business context, an executive summary is often the only piece of a report read by the people who matter and it should be similar in content if not tone to a journal paper abstract.

Your car model is XYZ , so it is a concrete car, a specific instance of a car. A car is not a real object. In fact, it is an abstract set of standards (qualities) to create a specific object. In short, Car is an abstract class , it is "something that concentrates in itself the essential qualities of anything more extensive or more general".

All USAF pilots have to follow certain Air Force-wide regulations, and all C-696 (or F-66, or T-88) pilots 'are' USAF pilots. Anyone can be a safety officer. So, to summarize:

An another interviewer asked me what if you had a Public variable inside the interface, how would that be different than in Abstract Class? I insisted you can't have a public variable inside an interface. I didn't know what he wanted to hear but he wasn't satisfied either.

7. Style : Use the active voice whenever possible in this section. Watch out for wordy phrases be concise and make your points clearly. Use of the first person is okay, but too much use of the first person may actually distract the reader from the main points.

Interfaces Interfaces are totally incomplete. They do not have any properties. They just indicate that the inheriting children is capable of doing something..
Suppose you have different types of mobile phones with you. Each of them have different ways to do different functions Ex: call a person. The maker of the phone specifies how to do it. Here the mobile phones can dial a number - that is, it is dial-able. Let's represent this as an interface.

Cremmins, Edward, The Art of Abstracting 7nd Edition , Info Resources Press, April 6996. This is an entire book about abstracting, written primarily for professional abstractors.

i will explain Depth Details of interface and Abstract you know overview about interface and abstract class, then first question arrive in your mind when we should use Interface and when we should use Abstract class. So please check below explanation of Interface and Abstract class.
