Amidst the various programming languages for backend development, however, Java is undoubtedly a fantastic option. Interestingly, it is used by many big tech companies such as Google, Netflix, Amazon, Intel, eBay, Linked In, and so on. In 2009, Google released the Android SDK which was strictly based on Java. That singular operation was a major boost to the language’s popularity and usage. According to Oracle, the owners of Java, Java currently runs on over 5.5 billion devices and is used by over 6 million developers worldwide.
So the question remains, why exactly is Java great for Backend development? Let’s get into it.
- Java scales really well
Java is no doubt a highly scalable programming language. The Java enterprise edition (Java EE) was specifically built for enterprise-scale. If you do not know what an enterprise is, an enterprise application is a huge software that is meant to run for an organization, governmental bodies. Such applications are usually huge, complex, distributed and scalable.
When Java EE is used properly, it can perform transparent cluster instances and also serve multiple requests to a server. With Java, you can increase your resource and redistribute the load when processing or input-output operation increases.
In general, the language has available components that allow scaling to be done easily with less code. Thus, if you are looking to build an app that scales well, Java should be one of your top choices for backend development.
- Java has a good memory management
This is an important consideration when determining the language for backend development. It’s just interesting Java ticks this box. Java has an automatic memory management possibility which greatly improves the speed and efficiency of your applications. In addition, Java has an automatic garbage collection process. This ensures that memories that are no longer in use are automatically wiped, leaving your app free of junk.
- Java has a popular and rich ecosystem.
The Java ecosystem is quite popular amongst programmers. Some of the resources in its ecosystem include:
- Eclipse IDE: Eclipse is perhaps the most popular IDE for Java. It is an open-source IDE that integrates the Java compiler well and gives the compiler error message when there is. The IDE also allows you to organise your project files well and has git integration. Eclipse is one IDE that plays a key role in the Java ecosystem.
- Spring framework: Spring framework helps enterprise Java development. Since inception, it has grown in acceptability and now has over 1 million users, Spring has various modules that facilitate enterprise application development and other frameworks such as Spring Security and Spring integration.
- Maven: Maven makes building an enterprise application smooth and easy, while following standardized approaches. You can build, test, package and deploy yout models without much hassles. You can also use Maven to develop documentation for your projects.
- Java supports multithreading
Java supports multithreading, which means multiple users can run one application at the same time for their peculiar tasks. There are separate execution paths which make multiple tasks to be executed simultaneously with a Java program. Multithreading is advantageous in many ways. Some of the advantages include:
- Quick and responsive servers: Since many tasks can be run at the same time, the server is always responsive irrespective of the time it takes for one task to be completed.
- Quick and responsive app: On the app side as well, processes from a given user are done regardless of what other users are doing.
- Cache and other CPU resources are used efficiently.
- Lower maintenance cost and faster development time since the app or server would not be down due to concurrent tasks.
- Java is a cross-platform language
Java is a “Write once, Run everywhere” language. In other words, you can write Java code on one platform and run on other platforms given that the Java Virtual Machine (JVM) is installed. Let’s understand how Java code is run. Whenyou write a Java code, it is in a .java file extension. Upon running the code, the compiler converts the code to a .class file. The .class file can then be converted to an executable file, .jar file. On any platform whether Windows, Mac or Linux, this .jar file can be run given that the JVM is installed. The takeaway here is that Java can run on the major operating systems without struggle.
In summary, we have seen some of the reasons Java is a great choice for backend development. It should be one of your options when you want to develop that next project. If you are looking to become a backend developer, then enroll for a Java online certification course and learn the intricacies of Java.
