Object Oriented Programming Concepts:
Class: Blueprint for creating objects.
Objects: An instance of a class.
Abstraction: Hiding internal details and showing functionality is known as abstraction. For example, phone call. We make a call but don't know the internal processing.
Encapsulation: Binding (or wrapping code) and data together into a single unit is known as encapsulation. For example, Capsule. It is wrapped with different medicines. A java class is the example of encapsulation.
Inheritance: When one object acquires all the properties and behaviours of a parent object or parent class, it is known as inheritance.
Polymorphism: If one task is performed in different ways, it is known as polymorphism. In Java, we use method overloading and method overriding to achieve polymorphism. Another example is: a cat speaks meow, dog barks woof etc.
