Object-Oriented Programming (OOP) consist of some important concepts namely Encapsulation, Polymorphism, Inheritance and Abstraction. These features are generally referred to as the OOPS concepts. If you are new to object oriented approach for software development, An object in OOP has some state and behavior. In Java, the state is the set of. Object-Oriented Programming: Object-oriented programming is at the core of Java. In fact, all Java programs are object- oriented—this isn’t an option the way that it is in C++, for example. OOP is so integral to Java. Therefore, this chapter begins with a discussion of the theoretical aspects of OOP. Two Paradigms of Programming.

OOP: Introduction 2 Pure Object-Oriented Languages Five rules [Source: Alan Kay]: •Everything in an object. •A program is a set of objects telling each other what to do by sending messages. •Each object has its own memory (made up by other objects). •Every object has a type. •All objects of a specific type can receive the same messages.

Examples: • Driving a car doesn't require knowledge of internal combustion engine; sufficient to think of a car as simple transport. • Stereotypes are negative examples of abstraction. To be useful, an abstraction (model) must be smaller than what it represents. (road map vs photographs of terrain vs physical model).

Java is a class-based object-oriented programming (OOP) language that is built around the concept of objects. OOP concepts (OOP) intend to improve code readability and reusability by defining how to structure a Java program efficiently.

As the name suggests, Object-Oriented Programming or OOPs refers to languages that uses objects in programming. Object-oriented programming aims to implement real-world entities like inheritance, hiding, polymorphism etc in programming. The main aim of OOP is to bind together the data and the functions that operate on them so that no other part.
