17 Aug Java for Beginners: Here’s Why You Should Start Learning Java Now
Respected by people across the globe, Java was launched in 1995 and remained one of the most popular programming languages, according to Statista. Unsurprisingly, Java developers are highly demanded and make perfect money.
What makes Java that popular? This article will do a short review of Java, its history, the main features of this exciting programming language, its development tools, and why you should learn Java to take your skills to the next level.
Brief History of the Java Programming Language
Java is by far one of the most popular and effective mainstream languages today, but the story of its origin is undoubtedly one to write home about. The programming language was created by a team of experienced software developers within Sun Microsystems. These guys, codenamed Green Team, were led by experts James Gosling, Mike Sheridan, and Patrick Naughton.
Initially, the team wanted to develop a universal language for household devices, like TVs, stereos, and VCRs. This new language would have saved programmers from rewriting the code for a different platform every time. It should have run on any platform! The speech was named Oak after an oak tree growing under Gosling’s window.
Oak’s breakthrough came when the internet was still in its nascent stages. Despite their best efforts, there was no such technology in the 90th to work with the devices they wanted. Anyway, they created the language that works on a Virtual Machine and supports different platforms for the decades to come.
In 1995, Sun Microsystems launched Oak as a new product, renaming it Java. The world was beginning to find new and improved ways to interact with each other and explore what the world wide web is capable of. Fortunately enough, one of Java’s founding members, Naughton, thought he should use Oak to create Internet applications.
As a result, Oak became an independent product. Soon, the Oak browser “WebRunner” and the Oak compiler were also written. Due to its security, reliability, and platform independence, Java proved to be the perfect match for the Internet, which is still used for multiple reasons even today.
Moreover, 1995 remains a particular year for the programming language because that’s also when it was first released publicly with the same name it has today. Since it came into the market, Java has been acclaimed by programmers and tech enthusiasts alike. Time magazine refers to the programming language as “One of the Ten Best Products of 1995.”
In addition, the Android operating system was built using Java. Accordingly, Java is widely used for programming for Android, along with Kotlin. Java is also used mainly for large Enterprise-level applications, or rather, for their backend part, for many solutions for internal development, especially when working with volatile data.
WORA – the Main Feature of Java
Java’s platform independence is one of the most attractive features of this remarkable programming language. When you learn Java, you don’t have to worry about changing large chunks of your code to work on different platforms. This very platform independence plays a crucial role in allowing Java to create mobile apps, server apps, eCommerce websites, financial trading platforms, scientific applications, and so much more!
Furthermore, Java programs are translated into Java bytecode and executed by the Java Virtual Machine (JVM), which processes byte code and passes instructions to hardware as an interpreter. The advantage of implementing programs is complete independence of the bytecode from the operating system and hardware, which allows you to run Java applications on any device for which there is a corresponding virtual machine.
Another important feature of Java technology is a flexible security system, within which the execution of a program is entirely controlled by a virtual machine. Any operations that exceed the program’s specified authority (for example, an attempt to access data or connect to another computer) will cause an immediate interruption.
The Java Virtual Machine is so extensible and widely used that plenty of languages run on it. For example, Scala, Groovy, and Kotlin, which is the official language for Android programming.
Here’s Why You Should Learn Java Now
Java is easy to learn, has immense potential, and has been around for decades – much longer than most programming languages today. So it’s always a good time to learn Java. This means that you’re bound to find a great community and answers to all your questions when you decide to embark on your journey of learning this powerful programming language.
Still not convinced? Here are some other great reasons why you should consider learning Java:
Java Is Beginner-Friendly
It’s easy (and very typical) to feel intimidated when you’re starting to code in a new programming language. Everything from the syntax to the semantics can leave you double-guessing your choice.
- Is this the correct language for me?
- Is this a good pace?
- Why does my code have so many bugs?
When you inevitably ask these questions, the only thing you need is a solid and friendly community to return to – and that’s what Java has. People have used Java for decades to create everything from financial management systems to video games.
This means that if you run into problems with any problem, the chances are high that someone already has the solution you are looking for. But that’s not the only way Java is newbie-friendly.
The lack of a garbage collector and direct memory access is the most typical difficulty for beginners working with languages such as C and C++. There are no such problems with Java. When working with Java, users are not (entirely) responsible for memory management and garbage collection. Since Java itself takes care of all of this, beginners can focus on the coding itself.
What’s more, online courses like those offered by CodeGym teach you everything you need to know about Java from scratch. You can chat with friends in the same community, view success stories to increase motivation, and practice your skills by completing up to 1200 coding tasks with a verification system.
There Is Always Demand for Java
If the popularity of a programming language remains stable even after three decades of its release, you know it has done something right. To this day, Java is used in almost all major industries to build robust applications. According to Oracle blogs, Java is used by about 9 million developers, and it runs on around 7 billion devices across the globe.
Java developers are also the preferred candidates for some of the highest-paying jobs globally and are constantly sought after by large and small companies. The latest data from employment website Indeed shows that the average base salary for Java developers in the United States is a whopping $102,839, including benefits, visa sponsorship, and 401(k).
Extend Application Capabilities With APIs
APIs are the lifeblood of all great applications today. They add a layer of abstraction to your applications to simplify otherwise complicated and complex tasks. APIs allow applications to communicate with external software and microservices to get the user response from the target system and vice versa.
Fortunately for beginners learning the programming language, Java has three main APIs, i.e., official Java core APIs, optional Java APIs, and unofficial APIs. You can use these APIs to extend the capabilities of your applications without compromising on simplicity and ease of use.
Java Has Plenty of Open Source Libraries You Can Use
Since it is an open-source language, you can rarely run out of support material when you’re using Java. There’s a vast collection of libraries that users can leverage to create high-performing applications without writing code for repetitive tasks.
Some popular libraries that you should look into include Apache Commons, Google Guava, and Maven. If you love getting into details, these libraries will also teach you a thing or two about Java’s best practices.
You Can Choose From Multiple Development Tools
The wide range of development tools available makes learning Java a breeze. Throughout the world, Java developers and beginners learning the language use such integrated development environments as Eclipse, Netbeans, and IntelliJ IDEA for their work and learning.
Each component of IntelliJ IDEA is designed to maximize developer productivity and make it effective. An intelligent code editor combined with an ergonomic design makes development not only efficient but also enjoyable. All the necessary tools are ready to be used. It means there is no need to search and install plugins for integration with version control systems and support for popular languages and frameworks.
In addition, IntelliJ IDEA provides a wide range of fast and efficient development features: intelligent completion, real-time code analysis, and reliable refactorings. These tools can help with various development tasks such as debugging, refactoring, and even highlighting syntax issues to help you learn and improve as a Java developer.
With all these benefits and unwavering fame, it’s clear that Java will be around for years to come. The sheer power and versatility of the programming language have been proven for decades, and Java continues to be loved by both beginners and veteran developers worldwide. And with Big Data and the Internet of Things gaining popularity, it’s safe to say that the demand for Java won’t decrease any time soon.
