Why Use Java for Back-end Development?

When starting a new software development project there is always a question, which programming language to choose? With a variety of different development languages and frameworks available on the market, it is a constant dilemma: Java or .Net? Ruby on Rails or Python or PHP? We are not going to compare these languages against each other in this article but rather try to answer the question: when and why Java is selected for backend development.

Actually, there are several parameters that depend on the language selection, such as language capabilities, easiness of coding, support of different OS and mobile platforms, size of the project and its domain specifics, availability of in-house resources who will be able to support the project further on, security and performance issues, etc.

We have already mentioned that Java remains one of the most widely used programming languages in the world. Such well-known companies as Google, Netflix, Uber, Airbnb, Spotify, Amazon and Facebook use it for its product back-end development.

So what are the main advantages of Java?


Java has been used by developers for more than 20 years and is considered to be one of the simplest languages to learn due to its less ambiguous syntax terminology derived from C++. Anyone who knows the fundamental principles of programming, can learn fast and start using Java right away.

Cross platform

Being an object-oriented compiled language, Java allows you to write the code once and run it anywhere on any platform (Windows, Mac OS, and Linux), making it a perfect choice for mobile application development, web development, database connectivity, networking, and many more.


Java uses a multi-threaded web server that processes each request in a separate thread. That enables to perform several tasks simultaneously without querying the events.

Multi-threaded processing makes Java a great tool for CPU-intensive applications, such as video streaming, image editing, etc.


Java is said to be more secure than any other programming language. Its security is obtained from a large set of APIs, tools, and implementations of commonly-used security algorithms, mechanisms, and protocols. Java APIs include cryptography, public key infrastructure, secure communication, authentication, and access control. JDK was originally developed with a strong emphasis on security allowing for creating secure applications from the very start.

Open source libraries

There is a large number of Java libraries of different purposes: logging, JSON parsing, unit testing, XML and HTML parsing libraries,messaging, PDF and Excel Reading libraries,

cryptographic libraries and many more.  Most Java libraries are open-source and supported by experienced Java developers. The use of such libraries significantly accelerates the back-end programming of web apps.

Rich Ecosystem

Java has a vast variety of frameworks and tools facilitating back-end development. The most widely used frameworks are Spring, Apache Struts, Grails, Hibernate and other frameworks mentioned in our previous blog post. Among other useful tools – Maven, Jenkins, NetBeans, Eclipse IDE – are worth mentioning.

Robust & scalable

The automatic memory management and garbage collection make Java highly scalable and speeds up the development of web applications. It also allows good and optimized code written.

Java has a strong type checking mechanism which makes Java robust. JVM (Java virtual machine) provides dynamic linking and a safe environment and allows Java to run everywhere.

Java Use Cases

Java has become a universal programming language both great for client-side and server-side applications, web and mobile applications. Java is predominantly used for the development of enterprise applications and cryptocurrency apps due to its security and scalability characteristics.

Java is also great for the development of IoT solutions, e-commerce development,and Big Data apps. And it is the main language used for Android app development.

Bottom line

Being one of the old-aged languages Java is still popular among the developers. This language can be used for the development of applications of all sizes both web and mobile as well as for developing enterprise-level applications and working with Big Data.
