Top 10 Important Characteristics of OOPS

In this blog post, we will be discussing object-oriented programming (OOP). This is a type of programming that has become increasingly popular in recent years. It allows developers to create objects that model the real world, which makes code easier to understand and maintain. We will go over the basics of OOP and how it works. Stay tuned for future posts in which we will discuss specific features of OOP languages!

What Is Object-Oriented Programming?

Object-oriented programming is a type of computer programming that uses objects to design applications and software. In object-oriented programming, each individual item in the program—or “object”—is treated as an entity with its own set of variables and capabilities. This makes it possible to create more complex programs by organizing related objects into groups and then treating those groups as a single entity.

Benefits of OOPS

One of the key benefits of using an object-oriented programming system is that it can make code easier to understand and maintain. When you break your program down into objects, each with its own individual functions, it becomes much easier to see how everything works together. This also makes it easier to find and fix errors, as you can pinpoint the issue more quickly.

How does OOPS Work?

Object-oriented programming (OOPS) is a type of computer programming where programmers define objects—data structures that contain related data and methods—and then work with these objects to create larger programs. OOPS systems use three core concepts: classes, objects, and inheritance. In addition to these, they also make use of other features such as encapsulation, polymorphism, and composition.

Difference between C++ and OOPS

  • In C++, variables are global by default. In OOPS, on the other hand, variables are local to the object they are defined in. This means that each object has its own set of variables that can’t be accessed from outside the object.
  • C++ also doesn’t have a concept of inheritance, while OOPS does. Inheritance allows you to create a new class that is based on an existing class, and then extend the functionality of that class. This can be useful for creating reusable code libraries.
  • C++ does have a concept of composition, which is similar to inheritance but doesn’t allow you to override methods. OOPS also has a concept of aggregation, which is similar to composition but allows you to override methods.
  • OOPS is typically seen as being more Object-oriented while C++ is more procedural. Procedural programming focuses on the sequence of steps that need to be taken in order to solve a problem, while object-oriented programming emphasizes objects and their interactions. OOPS systems are often used for larger projects, while C++ is more commonly used for system programming and low-level applications.

Characteristics of OOPS

The following are the top ten characteristics of object-oriented programming systems:

Rich set of data types:

In OOP, there is a rich set of data types that allow for more flexibility and reuse. This includes primitives such as integers and strings, as well as complex data types such as lists and trees.

Robust encapsulation:

The encapsulation mechanism in OOP allows objects to keep their state hidden from other objects. This helps to protect the internal workings of an object and prevents them from being changed accidentally.


With polymorphism, you can send a message to an object and have it execute different code depending on the type of object that receives the message. This makes your code more flexible, since you don’t have to change it every time you want to use a different type of object.

Dynamic binding:

With dynamic binding, the compiler determines which method is called when a message is sent to an object at runtime. This allows for more flexibility and eliminates the need for casting operators.

Message passing:

In OOP, messages are used to send instructions from one object to another. This makes programming more flexible, since you can easily change the order of operations by rearranging the messages.


Inheritance lets you create new classes that are based on existing classes. This helps reduce code duplication and provides a more efficient way of working with objects.

Classes and interfaces:

Classes and interfaces provide a way to group related objects together and define the behavior that they should have. This makes it easier to create and use complex objects, since you can simply refer to them by name.

Type safety:

OOP is a type-safe language, which means that the compiler will check your code for errors and prevent you from running programs that might crash or produce unexpected results.

Garbage collection:

Garbage collection is a process that reclaims the memory used by objects that are no longer needed. This helps reduce the amount of work that the programmer has to do in order to clean up after themselves.


OOP allows you to easily add new features to an existing system without having to make any changes to the codebase. This makes it easier to keep your code up-to-date and allows you to adapt to changes in the environment.

These are just some of the many characteristics that make object-oriented programming systems so powerful. By understanding these characteristics, you can write more efficient and reliable code that is better suited for modern applications.


In this article, we have looked at the top ten characteristics of object-oriented programming systems. We have seen how these characteristics can help you write code that is easier to understand and maintain. We have also seen how OOP allows you to easily adapt to changes in the environment, making it a good choice for modern applications.
