Declaring abstract to a class, may or may not hold abstract methods are called abstract class. They can only be sub-classed but not instantiated. Static methods and fields may be the part of an abstract class. When they are sub-classed, these sub-classes start implementing abstract methods in their parent class. In case if it does not it can be declared under abstract class.

*Declaration of the abstract method is completed without an implementation. For example:*

```
abstract void add(int x , int y);
```

Abstract classes can be used, under following affirmation:\

- Sharing the code among the closely related classes
- Declaring non-static fields. This would allow modifying and access to the object states to which they are known
- Classes which have been extended from abstract class should have access modifiers except for public those who had been loaded with multiple methods or fields

*Well, it was brief about why are abstract classes used in java...**\**Hope, you enjoyed reading!*\
