Programming remains an essential skill for IT professionals. Although the rise of more user-friendly development options such as HTML, the increasing diversity of devices and use cases has prompted an uptick in business demand for talented and certified programmers that can handle the rigor of Python, Kotlin or Java.But is Java training worth it? Long the front-runner in popular coding comparisons, Java now faces increasing competition from newer languages designed to facilitate mobile app development or support open-source initiatives.
Here’s what you need to know about the current state of Java, how to get started with Java training, and the career benefits of Java certification.
What is Java?Java is an object-oriented, general programming language used by more than 12 billion devices worldwide. Over the last two decades, Java developer Oracle has continued to improve this language by adding new features, functionality, and quality-of-life improvements.While other languages are closing in on Java for the “most popular” title, it remains one of the best languages to learn for IT professionals with interest in coding-based technology careers because it supports both multiple environments and modern programming paradigms. As a result, Java has a versatility that few other languages can match and — despite the shift in programming preferences — will remain an industry mainstay for decades to come.
How do I Start Learning Java?The ubiquity of Java code makes it easy to find free resources online if you’re interested in learning more about this programming language. Designed as a small and simple language that requires little training, prospective developers can easily get a handle on the basics and begin building straightforward Java programs.At a certain point, however, the sheer volume and variety of Java information will frustrate most beginners, leaving them with some Java knowledge but lacking the ability to leverage this code at scale effectively. To help focus your efforts and improve your Java skill, consider step-by-step online courses that both introduce key features and provide hands-on assistance to ensure you understand — and can effectively apply — critical techniques.Key Java concepts include:
- Abstraction — This process allows Java programmers to display relevant data to users while hiding unnecessary data from view. Common applications here include login portals — users see fields for login credentials but don’t see the process of verification and authentication.
- Encapsulation — Encapsulation focuses on binding data to code that manipulates it, which reduces the risk of both data and code tampering from external sources.
- Inheritance — This concept connects Java objects and allows them to acquire the properties of other objects under certain conditions. It also empowers hierarchical classification, which allows programmers to define specific relationships between Java objects.
- Polymorphism — Leveraging polymorphism in Java code allows objects to be processed differently based on their characteristics. This makes it possible to align specific actions with runtime events and deploy multiple process types.
The Advantages of Knowing JavaKnowledge of theoretical Java programming techniques combined with practical Java skills can help open new career paths for IT experts. With basic Java certification, technology pros can find work as:
- Java Developers — Develop the next generation of Java-based applications and services.
- Java Architect — Build frameworks and design strategies that support Java deployments.
- Web Developers — Create web-based applications that rely on Java to deliver end-user functionality.
- Database Administrators — Improve database management with Java coding tools and techniques.
Improving Your Java SkillsWith the need for clean, secure, and efficient code on the rise as companies deploy public-facing applications across cloud and local stacks, there’s a commensurate increase in demand for Java certifications. While saying you have “some Java experience” can help boost interest in your resume, listing an official qualification can bump your application to the top of the pile.Popular certifications include:
- Java Foundations Certified Junior Associate — This qualification demonstrates that you’ve mastered the fundamentals of Java and is designed for entry-level IT professionals. Candidates must pass a 75-question exam in 150 minutes with a score of 65% or better.
- Oracle Certified Associate, Java SE 5/SE 6 — This certification focuses on application development and project management using Java technologies. Some experience with Java other programming languages is beneficial before undertaking this qualification. Successful completion requires passing a 51-question exam in two hours with a score of 68% or better.
- Oracle Certified Associate, Java SE 8 Programmer — Designed for IT experts looking to expand their Java knowledge and leverage new programming features, this certification requires candidates to complete a 70-question exam with a score of 65% or better in 150 minutes.
