In the below example we will code a few lines in JavaScript to check whether we can create an abstract class and see whether we can satisfy its properties or not. Abstract class in Java: Abstraction defines the ability to make a class as "abstract" declaring with keyword "abstract" which is considered as incomplete. A class which is declared with the abstract keyword is known as an abstract class in Java. It can have abstract and non-abstract methods (method with the body).

Note: Using an abstract class, we can achieve 0-100% abstraction. Remember that, we cannot Example of Abstract class. Let's take an example of the Abstract class and try to understand how they can be used in Java.

They are mainly used as super classes. It has one or more abstract methods. An abstract method is a method without a body, which are not defined. Sub classes of abstract classes: It is possible to instantiate a sub class that extends an abstract class. An abstract class is a class that contains at least one abstract method.

It cannot be instantiated, or its objects can’t be created. A class inheriting the abstract class has to provide the implementation for the abstract methods declared in the abstract class. Example-2: Abstract class with the abstract method and public method The following example shows how an abstract class can be declared with variables, an abstract method, and a public method. The statements of the public method are defined inside the abstract class, but the body of the abstract method is empty that is implemented inside the subclass of the abstract class. Abstract classes are the same as normal Java classes the difference is only that an abstract class uses abstract keyword while the normal Java class does not use. We use the abstract keyword before the class name to declare the class as abstract. Note: Using an abstract class, we can achieve 0-100% abstraction.

And a constructor of abstract class is called when an instance of an inherited class is created. For example, say you have a class Vehicle which defines the basic functionality (methods) and components (object variables) that vehicles have in common. You cannot create an object of Vehicle because a vehicle is itself an abstract, general concept. A class which contains the abstract keyword in its declaration is known as abstract class. Abstract classes may or may not contain abstract methods, i.e., methods without body ( public void get(); ) But, if a class has at least one abstract method, then the class must be declared abstract. An abstract class is as abstract as they come — an unfinished 'blank' for a group of future classes. The blank can't be used as is.
