Java – the basics

Let’s address the basics before we dive into the details of Java. If you’re looking to learn a programming language, this will help you to determine whether Java is the best one to start with.

What is Java?

Sun Microsystems first published Java in 1995 as a programming language and computing platform. It has grown from humble origins to power much of today’s digital world by offering a secure platform on which many services and applications are built. New, innovative goods and digital services still use Java as a platform, showing its versatility and how future-proof it is.

Java is fast, secure, and reliable. Developers use Java to construct applications in laptops, data centres, game consoles, scientific supercomputers, cell phones, and other devices.

Why is Java so popular? The features of Java

Java is the world’s third most popular programming language, after Python and C – according to the TIOBE index, which evaluates programming language popularity. We can attribute the language’s widespread use to several notable features of Java:

• Versatility. Java has long been the de-facto programming language for creating Web apps, Android apps, and software development tools such as Eclipse, IntelliJ IDEA, and NetBeans IDE.
• Development tools. The Integrated Development Environment (IDE) is one of Java’s most intriguing features. The Java IDE is a collection of automation tools, editors, and debuggers.
• User-friendliness. Java features an English-like grammar, making it ideal for novices. You can learn Java in two stages: core Java first, then advanced Java.
• Good documentation. Because Java is an open-source programming language, it is completely free. Java is well-documented, which is an important feature of the language. It includes a full guide that will explain any issues you may encounter when coding in Java.
• A robust API. Although Java only has about fifty keywords, its Application Programming Interface (API) is wide and comprehensive, with various methods that may be used directly in any code.
• A large community. The community support for Java is one of the drivers behind its popularity. It has the distinction of being the second-largest Stack Overflow community.

Java vs JavaScript – what’s the difference?

Despite both having ‘Java’ in their name, Java and JavaScript are two separate languages. While Java is an object-oriented programming language, JavaScript is an object-oriented scripting language. Java is mainly used for server-side development, while JavaScript focuses more on client-side scripts.

You can read more about what JavaScript is used for in our full blog post. If you’re interested in learning how to use JavaScript, our course from the University of Michigan can help you get started.

Why learn Java?

So, now that we know why Java is so popular, why should you learn how to use it? Aside from the simplicity of usage and versatility, there are several reasons to learn Java:

Java programmers earn big

Over the next decade, software developer jobs are predicted to expand by 22%, with backend developers in particularly great demand due to their specialised skill set. Furthermore, the average base wage for backend developers in the United States is $80,000, which is 54 percent higher than the national median income.

These figures are encouraging for Java developers, who are among the best-paid programmers in the industry. Java developers now earn an average of $91,465 per year, which is comparable to that of other mainstream language developers.

Java is easy to learn

The programming language was created with new developers in mind, providing a safe environment for them to experiment with the language and make mistakes. Java is a broad and high-level language that focuses on programming rather than complicated details.

Java is a great starting point for other programming languages

After learning Java, it’s relatively easy to learn other coding languages such as C, C#, C++, Python, and more. Java teaches novice coders how to think like a programmer, going through processes using logic and putting ideas to the test.

Java is a widely used and popular programming language

Almost every operating system uses Java, from the web to mobile to desktop. The Java programming language, which is widely used with corporate applications and Android mobile operating systems, is regularly updated to stay up-to-date with industry developments and can support a wide range of languages throughout its platform.

Java isn’t going anywhere

The digital world is constantly changing, and developers are looking for new languages and frameworks to give them an advantage. While being current is crucial, staying on trend can be costly and ineffective when industries shift. As a result, the importance of Java cannot be emphasised, especially as new languages and technologies emerge.

Java is a flexible language

Java is not only widely used in technology, but it is also easily scalable and, most importantly, highly portable, as it must be run on a cross-platform Java Virtual Machine (JVM). This JVM transmits platform-specific instructions to your computer, which means that once a developer produces code, they can port it to another system on almost any computing device.
