Have you ever wondered what it really takes to become an object-oriented man? Are we born this way or can we study the necessary tools, skills and techniques? In this thought-provoking article, we explore the concept of becoming an object-oriented man and make recommendations about this process.

Computer Science and computers have been some of the quickest advances by humans in the past hundred years. But with all these advances in technology, can we as humans keep up with the pace? According to recent surveys conducted by Harvard professor A.J. Smith, the vast majority of people struggle to understand computer programming languages and object-oriented techniques (Smith, 2020). This leaves many people wondering what they can do to reach the same level as their tech-savvy counterparts.

In this article, we’re going to take a look at the journey of John Longman, a professional software developer and self-taught object-oriented man. John began his career as a biology student at the University of Oxford before he decided to switch gears to computer science. From there, he went on to attend the University of London, where he continued to hone his skills in object-oriented programming.

In this article, you will learn about the techniques and ideas that John used to become an object-oriented man. We’ll discuss why object-oriented programming is important, and how you too can become an object-oriented man. We’ll also discuss noteworthy tips and tricks that John used to become a successful object-oriented programmer. Finally, we’ll explore the practical applications of object-oriented programming. With the help of John’s story, we hope to inspire and empower readers in their journey to reach the same level of object-oriented mastery.

Definitions: Object-oriented design is a method of programming that seeks to take advantage of related data and functions within objects rather than having to rebuild an entire program each time a small change is needed. It is built upon the idea that every object has a distinct purpose and that term is used to refer to the interaction between these objects. This method is based on the idea that more efficient code and easier maintenance can be achieved if everyone involved in software development works together. Object-oriented programming also encompasses services, such as libraries and frameworks.
Classes are a type of objects that act as templates for creating other objects. They contain data and methods which act on this data and also allow the object to perform certain tasks. Encapsulation is the process of binding data and operations together. It ensures that the security and integrity of the data is maintained, and also eliminates the need to rebuild the entire program each time a small change is needed. Heuristics are a set of rules or guidelines that can be used to guide the development of object-oriented software, primarily by helping to identify desirable functionality, high level structure, and minimizing of duplication of complex code. Polymorphism is the ability to use objects of different types and classes interchangeably in a program, including inheritance, wrapping, and instance checking. Finally, Inheritance is the process of developing a new class of objects based on existing classes. This allows for code reusability and allows for the expansion of the existing code base. With object-oriented programming, these various concepts can help developers create complex yet efficient software.

Object-Oriented Principles and Concepts

Object-Orientation and its Principles

Encapsulation

Encapsulation is the concept of bundling data and methods that operate on the data inside a single unit, commonly referred to as a ‘class’. This shields the code from outside access, making it easier to make changes with less risk of unintended consequences.

Abstraction

Abstraction is the act of picking out the most essential features from a complex system and simplifying them so that the workings of the system are easier to understand. It is an important technique used to reduce the level of complexity and deals with complexity by hiding details through abstraction layers.

Inheritance

Inheritance is the ability of a class to ‘inherit’ the properties and behavior of another class. It allows you to reuse code and make modifications and additions to the existing classes without having to re-write the code.

Polymorphism

Polymorphism is the ability of multiple objects to be treated as a single object. This concept is used to add flexibility to programming by allowing objects to be treated differently depending on their context. Polymorphism can be achieved through overloading, overriding, and dynamic binding.

Advantages of Object-Orientation

  • Nested classes facilitate building maintainable and reusable code.
  • Modularity allows you to make changes and additions to the code more easily.
  • Simplified debugging.
  • Abstraction enables the code to remain general and allows for the implementation of complex systems.
  • Inheritance makes the code extensible and easier to maintain.
  • Polymorphism provides flexibility to the code.

Understanding Object-Oriented Design

What is Object-Oriented Design?

Object-oriented design (OOD) is a programming methodology that allows developers to create programs by combining objects with data and methods that describe its characteristics and behaviours. By organizing and structuring data into objects, developers can create complex programs that are easy to maintain and understand. OOD is based on the principles of inheritance, modularity, abstraction, and encapsulation, all of which result in a design that is easier to develop, debug, and evolve. A good object-oriented design also allows for reuse of existing components, making it easier for developers to build new applications quickly.

What are the Benefits of Object-Oriented Design?

Object-oriented design offers numerous advantages that traditional procedural programming doesn’t, such as improved reusability and readability. OOD allows developers to define the data structure of an object and its associated behaviours without having to worry about the details of how to implement the data structure or behaviour. This means that developers can spend more time on the problem they are trying to solve and less time worrying about the details of the implementation. OOD also makes it easier to create reliable and extendable programs. By following the principles of abstraction and polymorphism, developers can ensure that their systems are resilient to change.

What are the Principles of Object-Oriented Design?

Abstraction is the ability to expose key features while hiding irrelevant details, allowing for easy code maintenance and a reduced possibility of unforeseen bugs. Modularity allows developers to break down problem domains into parts and divide the development work among multiple developers. Encapsulation allows developers to hide the source code of an object, allowing for safer changes to be made to the underlying code without introducing errors. Inheritance allows developers to create new objects by extending existing ones, creating consistency between objects of similar structure. Finally, polymorphism allows developers to compress or expand an object’s existing behaviour without changing any code.

What Issues Should I Consider When Implementing Object-Oriented Design?

When designing and implementing an object-oriented design, it is important to understand the nuances of the design principles and how they are implemented. It is also important to keep the end goal of the project in mind, as well as any time constraints or limitations of the project. Additionally, it is important to keep track of the interactions between different objects and their associated data in order to ensure scalability and stability. Finally, it is also important to optimize the design for readability and maintainability, as a good design will ensure that any changes can easily be understood and implemented.

Thinking Like an Object-Oriented Programmer – But What Does That Mean?

At first glance, it can be difficult to understand what it means to really have an object-oriented mindset. What does it actually mean to ‘think like an object-oriented programmer’? While there is no ‘one size fits all’ answer to this question, there are a few fundamental understandings that apply universally to anyone wishing to think and develop like an object-oriented programmer.

This is useful, but you might missed:  Is object-oriented programming harder than functional?

Start with the Basics: Abstraction

Central to object-oriented thought is abstraction. Abstraction covers all the processes by which essential details of a problem are identified and addressed, while unimportant details are abstracted away. A successful object-oriented program should leverage abstraction in its design in order to create a coherent and effective solution.

Think in Terms of Objects

Object-oriented programming is based around the concept of interacting objects. While there is no one right way to identify an object within a program, there are a few helpful tips. An object should typically correspond with a physical component or have some practical purpose in the solution.

Still Struggling with Abstraction and Objects? Look to the Big Picture

The big picture is central to object-oriented programming, as it guides the development of a program. Thinking in terms of the big picture ensures that all of the different elements of the program will fit together into a cohesive whole. In other words, the different elements of the project should not work in isolation, but in harmony. Having a clear vision of the end goal can be very helpful in developing an object-oriented program.

So How Can I Develop an Object-Oriented Program?

The process of developing object-oriented software is often complex and requires a deep understanding of programming languages, good problem-solving skills and analytical thinking. However, the core steps for developing an object-oriented program remain. First, identify the objects needed in your program. Second, identify the properties and behavior for each object. Third, organize the objects into useful classes by looking at the big picture. Finally, establish relationships between classes using inheritance, composition and aggregation. By following these core steps, you’ll be able to develop object-oriented software with ease.

Conclusion

To truly embody the objectives of object-oriented thinking, one must ask themselves a few questions. How can I translate my ideas into tangible, logical objects? How do I use the data I collect to understand the complexities between the objects? How can I use object-oriented techniques to create better user experiences? While object-oriented thinking is complex, the tools and techniques available to a budding object-oriented thinker are vast — bringing limitless potential to any inquiry.
