Java seems like an ancient programming language, but many current frameworks and newer languages are based on it. And, of course, it’s still widely used around the world. Java has a simple approach – you write code once, and you run it everywhere.
What does it mean?
You can develop Android applications, advanced web solutions, and even games using Java. Even though it was invented back in 1995, today, we still use Java for many devices and online applications.
What do we know about Java?
Java is an object-oriented programming language. It’s easy to use, reliable, and pretty popular among programmers. They say you can’t really be a software engineer if you don’t know Java, and they are probably right.
Almost every IT company is looking to hire Java engineer to help them with the projects and become an essential part of the team. But what are those people doing in an IT company?
First, they build mobile and cloud-based applications but also work on enterprise apps. Then, they need to develop advanced marketing tools, chatbots, and even AI-supported devices.
And what do you get with Java?
It’s a robust and simple portable programming language. At the same time, it’s secure and platform-independent. The multi-threaded nature allows the programmers to execute the programs simultaneously while saving memory on the disc.
Experienced Java developers know many things, like what does static mean in java, and they can be mentors to beginners and less-experienced programmers. Being an engineer is a long career path, but you can easily accomplish your goals with the right knowledge and tools.
Why do we love Java?
Java offers scalability, which is essential to any system. It’s functional, secure, and still relevant almost three decades after its invention. The cross-platform availability means the JVM machine can understand the code and convert it into a bytecode, so any platform can understand it.
Java also comes with advanced memory management, which means it won’t spend your memory resources on so-called garbage collection.
Many tech companies use Java
Companies like Netflix, Airbnb, Pinterest, and Google still use Java for their projects. Also, NASA’s service, World Wind, is based on Java.
If you’ve ever played Minecraft, you have to know that the whole game is written in Java. It’s the same with Netflix and Spotify.
So, we can say you get in touch with Java solutions at least once a day. The truth is you aren’t often aware of it, but Java is all around you with every piece of technology you use daily.
What can you build with Java?
Java is used for so many tech solutions, including:
Mobile Apps for Android
Android users know that Java is the official language of the operating system. Kotlin is often used for Android app development but still uses the Java Virtual Machine to interact with the code and “translate” it as needed.
Useful Web Applications
Java was first used for web apps that use the browser. Probably you all remember the mini-games we used to play before 2010 without downloading them. Also, many other functional apps exist thanks to Java and its availability on any device.
Desktop Apps
We still use desktop apps, even though many things are available online. But these apps work offline too, and that’s possible because of Java.
IoT Solutions
IoT or the Internet of Things, is the network of physical devices connected to exchange data through the internet. As you suppose, Java plays a huge role in making all these things possible.
Data Processing
Java allows us to build apps to process big data. Usually, developers use frameworks, so they can spend less money and time in building complex data processing apps.
Can I use Java frameworks?
Sometimes frameworks ease the whole development process. Usually, these tools have pre-ready code pieces, integrated libraries, and database support. They are made for business purposes, which means developers use frameworks to provide advanced business solutions. If you write Java code from scratch, you will spend a lot of time testing it and fixing bugs.
You may not need to learn how to round in java when using frameworks, but you will stick to the basic principles of creating functional solutions.
Depending on what you need the framework for, you can choose between Spring, Hibernate, Grails, JavaServer Faces, Play, or Blade framework. All of them have different purposes, so you must find the one that fits your project requirements.
Why learn Java coding?
Becoming a Java engineer starts with basic coding. You can go to university and study for a software engineer, or you can find a course to help you master the programming language. Luckily, there are so many resources online, so going to university to learn Java may not be the best solution.
Once you master it, you will be ready to work on high-end enterprise applications and get hired by big IT companies. Even though Java is an old programming language, many modern frameworks, environments, and development tools are based on it.
Also, the process won’t be easy as it seems. You need to dedicate enough time and effort to memorize the protocols and rules, but it will become a routine for you at some point.
You can use the community help to become better and practice your skills daily. We suggest using online practice resources. Try to write your code as a solution and then compile and debug it. Test the performance, and see if you did all things properly.
As you improve, you are also getting more competent to apply for serious jobs and projects. And that’s why you need to learn Java now.
Final thoughts
In 2022, Java will be used for many things, especially Android and web applications. We come across some Java solutions every day we spend on the internet. Whether you use an app for private purposes or professionally, chances are the whole app or essential tools are written in Java.
And if you are a talented programmer, you surely can focus on building a career as a Java engineer and developer.
