What is Object Oriented Design?

Object oriented design is an approach to programming software that requires the software programmer to design a flow of code in which various objects that the code creates or manipulates interact with each other to resolve a problem or perform a task. This approach has become a vital one in modern programming, as object-oriented design and programming informs a huge range of digital functions from smartphone platforms to social media sites.

With the object-oriented approach, objects of one particular class may override or manipulate objects of another coding class, and problems between back-end code and the user interface can be more easily resolved and the interaction between the two can be streamlined. A number of languages that perform these functions exist, though some or more obscure than others. Here are three examples of languages used for object oriented design.


Python was created to be one of the cleanest programming languages of the twentieth century, and is still widely used. Python uses an approach that demands fewer lines of code than other programming languages for the intended functionality, and was created to be one of the most readable coding languages, making it easier to edit by software programmers who did not create the original code they are editing. An object creation and scripting language, modern platforms and programs that heavily or entirely use Python include Wikipedia, Google, Reddit, and Dropbox.


A more general and multi-functional programming language, Ruby is commonly used to execute truly brilliant user interface design – particularly because of its stability and routine updates to its already-expansive functionality. Ruby was written to be as comprehensive as possible to experienced computer and software programmers, and is unique in that every single value produced by the code is, in fact, an object. Ruby is also capable of metaprogramming which is a quality not commonly seen in object-oriented programming languages, and is used in major online platforms like Shopify, SoundCloud, and Groupon.


Even those who are not programmers have heard of Java. Java runs on millions of machines worldwide, and is one one of the most-used programming languages on Earth. Like Ruby, Java is a general and multi-functional programming language that excels at object-oriented design – partly because it’s designed to have as few contingencies as possible, thus minimizing errors in coding. Java’s heaviest use lies in web server applications, from online banking to chat servlets. It is also used as an enhancement language for a number of platforms and systems, including Windows and Android platforms. Currently, nine million developers worldwide program in Java, and Java routinely updates on millions of devices the world over to support everything from runtime compilers to user interface tweaks.

Object-oriented design has become incredibly important in the twenty-first century – with the entire world online, solid object-oriented design and programming has become an integral skill to billions of computer programmers all over the world. From interactive websites to digital security, object-oriented design has become an indispensable part of how we live, think, and navigate in an online world.
