How Do You Gain Expertise in Java?
3 yrs ago
There are a lot of programming languages out there and one of the most in-demand is Java. James Gosling and Patrick Naughton developed Java while they were still employed by Sun Microsystems, Inc. Their goal was to develop a programming language that applies to small electrical devices, allowing them to communicate with each other. Work began in 1991, and Java made its public debut in 1995, providing interactivity and multimedia to a wide range of devices, including those that use the world wide web. What sets Java apart from other programming languages is that it is designed to be compiled to a bytecode instead of the conventional native code. Through the Java virtual machine called Java Runtime Environment, the bytecode is then interpreted and translated for a host computer. This allows Java codes to be written in the same way for various platforms. Hence the guarantee, “write once, run anywhere,” proving Java’s executability, maintainability, and security. Over the years, Java has become one of the go-to programming languages of developers and development companies. That is all thanks to its simplicity and familiarity, which is due to its borrowed syntax from C and C++. Today, it is increasingly being used in the development of web, enterprise, and mobile applications. It also runs on about 7 billion devices, according to Oracle’s blog. As a result of that popularity, there is an array of career opportunities for Java developers, with more than 9 million job openings worldwide. These opportunities also pose some of the highest salaries in the tech industry, with experienced developers earning an average of £55,728 per year. Career demand and high salary aside, another reason to learn Java is that it is an excellent precursor to learning other programming languages. As mentioned earlier, Java’s syntax is based on C and C++, which means that the learning curve for those two other languages will be easier since you already have the foundation knowledge for their application. Perhaps one of the most significant advantages of learning Java is the versatility it provides. You can run the same code on multiple systems, including computers, game consoles, applications and more. So if you need to scale something, you can do so with ease. On top of that, Java comes with several open source libraries, such as Maven, JHipster, Apache Commons, and Google Guava; powerful integrated development environments like NetBeans, Eclipse, and IntelliJ IDEA; and an abundance of APIs. The accessibility of these tools can make the development process easier, faster, and economical. Now that you are familiar with Java and understand its advantages over other programming languages, it is understandable if you would like to learn and gain expertise in Java. To help you do that, we have come up with some useful tips that will allow you to learn faster. A strong foundation of knowledge is necessary to develop Java expertise. Afterall, everything about Java relies upon the fundamentals, allowing you to see the bigger picture as you move to more complex information of the discipline. Understand the concepts, terminology, structure, methodology, practices, and environment. Do not rush through learning the basics because doing so will only confuse you and may even lead you to miss out on essential stuff. Instead, take it slow and ensure that you are familiar with concepts before moving on the next level. As one adage goes, “practice makes perfect,” and that rings true when learning Java. Coding daily for at least 15-30 minutes will allow you to put your knowledge to practice. By applying code blocks and programming concepts, they eventually become second nature to you. As a result, you become more effective, efficient, and confident in resolving complex programming issues. It is normal for you to have days when you cannot understand a single Java concept or code snippet you are reading. You may even encounter coding problems that are too difficult to figure out on your own. In such a case, having someone more experienced in Java to consult with can be helpful, and joining a community is a great way to do that. The great thing about Java programming is that the discipline has a robust online community. More expert or experienced members are willing to share their knowledge to help beginner Java users to make better sense of the language. They can also be an excellent source of additional resources that you can use to support your learning. Another effective way to develop Java expertise is to participate in coding challenges. These are timed events where you try to identify and solve problems through coding, following given scenario and specifications. They come in various levels, from beginner-friendly coding challenges to more advanced level programming. The point of these challenges is to hone your Java expertise, develop your creative thinking and problem-solving skills, and improve your ability to collaborate with others, as some competitions encourage participants to work as teams. Participating in them will also help beef up your resume, especially if you win, which should make you a more desirable candidate for hiring companies. If you find the self-learning route challenging to develop your Java expertise, consider finding and working with a Java mentor. Being involved in a mentoring relationship will allow you to leverage the knowledge and experience of someone who knows Java in-depth. With that, you have a trustworthy resource you can consult for advice and support, improving the way you retain information and growing your awareness of how certain things get done using Java.
