Learn Object-Oriented Programming: Skills and Outlook
For a career in tech, it’s important to understand object-oriented programming. It undergirds programs that are large, complex, and frequently updated — characteristics that many applications that keep businesses and organizations running share. Accordingly, object-oriented programming is used in several popular programming languages, such as Python, Java, and C++.
Object-oriented programming has a long history, going back to the 1960s, and holds a spot near the top of any software developer’s set of skills. It has a steeper learning curve than other programming methods, but the effort pays off in the long run in flexible, efficient programming.
What Is Object-Oriented Programming?
Object-oriented programming is a major programming methodology (or specific way of designing a program), alongside other frequently used methodologies, such as imperative, procedural, and functional.
In object-oriented programming, the functions the program is designed to run are contained in objects, which are also called modules. The object contains the coding that accomplishes a task, such as updating an email address in a database or changing a shipping date or destination in an e-commerce application.
At its most basic, the programming method is like using building blocks — the objects — to structure a program. Another feature is that the objects can be used in other programs. If the program were a book, each object would be a chapter. The author could adapt the book for different audiences by adding or subtracting chapters.
Core Features of Object-Oriented Programming
Several key characteristics drive how object-oriented programming works:
- Classes, which are data types for objects, characteristics, and processes.
- Encapsulation,which means that the information and functions of the block are present in the block, and the program doesn’t have to search elsewhere for instructions.
- Abstraction,which is the capability of the module to interact with other modules. It works like a door to the module that allows the program to get access to the module.
- Inheritance,which is the capability to reuse the object without writing new code.
- Polymorphism, which allows the object to share functions even in another program.
Why Learn Object-Oriented Programming?
With proficiency in object-oriented programming, a programmer can write programs that are in demand in business, government, and organizations.
Object-oriented programming offers the programmer the ability to break large, complex programming projects into smaller pieces. Instead of writing line upon line of code, the programmer can complete the development in smaller chunks, each addressing a certain function of the program.
The method’s modular structure also makes it easier to find problems. Instead of combing through those lines of code, the programmer can zero in on a specific module and resolve the error quickly.
Another advantage of modularity is that it enhances collaboration since colleagues can slot your modules into their programs and you can insert their modules into your programs.
Among the disadvantages of object-oriented programming are that its theoretical underpinnings must be mastered before it can be used and that it demands more computing resources, such as memory, than other methods.
Object-Oriented Programming Skills
Object-oriented programmers must be able to see the big picture while maintaining a sharp eye for detail. Other necessary skills include the following:
- Knowledge of programming languages
- Ability to learn and use abstract concepts in multiple situations
- Mathematical capabilities
- A knack for problem-solving
- Oral and written communication capabilities
In addition, object-oriented programming calls for familiarity with these technologies:
- JavaScript
- Git
- Java
- HTML
- C#
- MySQL
- SQL
- Bootstrap
- C++
- Python
- Linux
Object-Oriented Programming Outlook for Job Seekers
The job outlook is generally good for programmers with knowledge of object-oriented programming. Programmers who use computer languages that allow object-oriented programming — C++, C#, Java, and JavaScript — are in high demand.
Object-oriented programmers make an average of about $90,000 a year (nearly $45 per hour), according to Zippia, a jobs listing website. The average for the lowest 10% is about $69,000 a year, while the highest 10% bring home an average of about $117,000 a year.
Industries with the highest demand for object-oriented programming coders include the following:
- Financial services
- Health care
- High tech
- Professional services
- Real estate
- Retail and e-commerce
