We can provide the solution of real word problem if we are using the Object-Oriented Programming language.Įxample of Procedural Oriented Programming vs Object Oriented Programming OOPs provides ability to simulate real-world event much more effectively.OOPs provides data hiding whereas in Procedure-oriented programming language a global data can be accessed from anywhere.OOPs makes development and maintenance easier where as in Procedure-oriented programming language it is not easy to manage if code grows as project size grows.Advantage of OOPs over Procedure-oriented programming language A class typically consists of data members (data) and member functions (code that operate on the data) together. ![]() A java class is the example of encapsulation. ![]() Encapsulation –īinding (or wrapping) code and data together into a single unit is known as encapsulation. In java, we use abstract class and interface to achieve abstraction. For example: phone call, we don’t know the internal processing. Hiding internal details and showing functionality is known as abstraction. In java, we use method overloading and method overriding to achieve polymorphism. In terms of programming, a function might behave differently in different scenarios and this functionality is known as polymorphism. When one task is performed by different ways i.e. We will study in detail about this in further tutorials. It is used to achieve runtime polymorphism. When one class acquires all the properties and behaviours of parent class i.e. It does not have physical memory, however when we create object of that class, memory is allocated in the RAM. Any entity that has state(variables aka member functions) and behavior(functions aka member functions or methods) is known as an object. In simple terms – An Object is a variable of type ClassĬlass is just a template at we declare (or its predefined). Data is hidden and cannot be directly accessesĭiagramatical Representation of POP vs OOPĪ class is a template which consists of data members (variables or other objects) and member functions using which we derived Objects.Functions that operate on the data of an object are tied together in that same data structure.Data structures are designed such that they characterize the Objects.Emphasis on Data rather than the procedure.These objects are derived out of Classes (consider them as custom templates that we users can define and there are inbuit classes and objects too). Programs are organized in terms of Objects which have the data and functions that access that data. In Object Oriented Programming, focus is given on data and how to access that data and the real world scenarios share more resemblance. Group of similar tasks are organized as functions.List of instructions for a computer to follow.Also this type of programming is at times not suitable for real world scenarios (we will see and example). In this type however, data is usually global and focus on how to access data is not taken into account. function named add() might perform addition of 2 or n numbers). Functions are group of program statements with same name used to perform common task (e.g. ![]() In procedural programming major focus is on functions rather than data and hence we have programs divided into modules aka functions. To better Understand this definition lets try to see what procedural programming is – Procedural Oriented Programming – ![]() OOP is an approach that provides a way of modularizing programs by creating partitioned memory area for both data and functions that can be used as a template(Class) for creating copies of such modules on demand (Objects) Lets first Understand what exactly is Object Oriented Programming in Detail – Object Oriented Programming Definition – Java is an Object Oriented Programming Language. In this Java programming tutorial post, we will take an introduction to Object Oriented Programming in Java.
