In this tutorial, we have discussed abstraction in Java in detail. Abstraction is a technique of hiding unnecessary details from the user. The user is only given access to the details that are relevant. Vehicle operations or ATM operations are classic examples of abstractions in the real world.

Abstraction in the real world Making coffee with a coffee machine is a good example of abstraction. You need to know how to use your coffee machine to make coffee. You need to provide water and coffee beans, switch it on and select the kind of coffee you want to get.

Abstraction means displaying only essential information and hiding the details . Data abstraction refers to providing only essential information about the data to the outside world, hiding the background details or implementation. Consider a real life example of a man driving a car.
Read moreWhat is the purpose of using abstract classes?
The purpose of an abstract class is to provide a blueprint for derived classes and set some rules what the derived classes must implement when they inherit an abstract class . We can use an abstract class as a base class and all derived classes must implement abstract definitions.

The purpose of an abstract class (often referred to as an ABC) is to provide an appropriate base class from which other classes can inherit . Abstract classes cannot be used to instantiate objects and serves only as an interface. Attempting to instantiate an object of an abstract class causes a compilation error.

Read moreWhat is an abstract class in C ++? Why it is required?
By definition, an abstract class in C++ is a class that has at least one pure virtual function (i.e., a function that has no definition). The classes inheriting the abstract class must provide a definition for the pure virtual function; otherwise, the subclass would become an abstract class itself.
