Java is a general-purpose development platform whose main value offering has always been "Write once, run everywhere." At present, it is practically ubiquitous: you can find Java applications from small connected devices of the "Internet of Things" (IoT), to servers, through desktop management applications, mobile developments, video games and many more.
There are various reasons, technical and non-technical, for the popularity of Java, but what are the main technical value propositions for developing with Java?
There are many more features than those listed below and they are not exclusive to Java for the most part. There combination is what companies usually value and that’s exactly what Java offers:
Although it is not as great an advantage and there are many other platforms that offer cross-platform. The fact that Java works on practically any device, server or operating system, is still one of its main attractive to many people. There is an implementation of the Java virtual machine for just about any system we can think of.
In addition, we must not forget that Java was initially designed to run on embedded devices, with many memory and power limitations, so depending on where we run it, it can be very helpful to rely on the language.
There are other languages like C ++ that offer more performance and more control, but are much more difficult to handle without messing up. Java is a language that offers automatic memory management and whose objects do not refer to data outside of themselves or other Java objects. This makes it impossible for a Java instruction to corrupt memory, or "stomp on" or compromise data from other applications or the operating system itself. The virtual machine performs all kinds of integrity checks that prevent it from breaking the operating system or other programs.
It also manages the freeing of memory automatically, so it uses it efficiently without the programmer having to worry about anything.
Again, this is not unique to Java, as other platforms, such as .NET, have the same protections, but it is an advantage over more traditional platforms.
Thanks to its object orientation, it is easier to create modular applications and reuse parts of them, in addition to allowing the implementation of better proven design patterns that contribute to its robustness. It is also one of the reasons why the platform itself is so extensible and has so many native or added functionalities.
Apart from the enormous amount of basic functionality that the platform itself already includes ready to be used, with Java you have a lot of third-party code ready to be used.
Between the fact that it has been with us for well over two decades and the community is huge, there are countless libraries and utilities created to extend the functionality and improve the Java platform.
Almost anything you may need, you will surely find it already created in an open source project. Not only that: many of the best known and most used libraries have been created and maintained by large organizations such as Google, Facebook or the Apache foundation, which is always an additional guarantee.
This makes life much easier for programmers and there are not many other platforms that can provide the same exuberant variety of usable code.
It is easier to learn and code compared to classical languages like C or C ++. In general, it can be said that Java is not a more difficult language to learn than any other, especially modern ones like C# or Swift, but it is easier to learn than many others.
Thanks to specialized and free tools like NetBeans and other editors or development environments, compiling, debugging, and deploying is a breeze, and getting started is easy.
Like any complex and general-purpose platform like this, you have two challenges learning it:
Java was created because C and C ++, which were the languages used in the mid-80s, were not totally convincing to address security issues. But they were the most used languages at that time. They are still the most common languages used today, which is why everyone who knew how to program knew C or C ++. Most programming languages are based on the syntax of these languages. This makes it easy for anyone who wanted to learn Java.
Java eliminates the least used functionalities by these languages and also the most confusing ones. This ensures that programming is simpler in Java by detaching the programmer from certain tedious tasks. Handling of pointers is one of the most outstanding characteristics that has been eliminated. This handling was done by the programmer in C, but Java itself manages this error.
Java uses the object-oriented paradigm. The object-oriented programming is the predominant paradigm nowadays. It allows building large systems of a modularized form so that they are easy to manage. Thereby, improving the quality of the systems and reducing the number of failed projects.
The aspects of the Java development are diverse. For the development, companies should turn to an experienced service provider such as Hyperlink InfoSystem. Hyperlink InfoSystem was established in 2011, and we have already successfully implemented numerous ideas and have extensive practical experience. Regardless of whether it is a native app for Android, softwares for wearables or computer, or a special application to support internal processes - Hyperlink InfoSystem has so far been able to master every challenge to the satisfaction of its customers.
