Java Free Online Course with Certification [2020]

The PYPL Popularity of Programming Language Index maintains that Java is the second most popular programming language in the world, after Python. 

Although the programming world is fast-evolving, Java has remained a constant in the programming and software development world ever since its inception. It has evolved and upgraded continually to keep pace with the changing software development needs. 

What is Java?

James Gosling at Sun Microsystems developed and launched Java way back in 1995. It is a general-purpose, class-based OOP programming language that is designed to have minimal implementation dependencies. Java’s syntax is primarily based on C and C++. This allows developers to create stable, secure, and resilient applications that can run on multiple platforms, including Mac, Linux, and Windows operating systems.

The best part about coding in Java is that it follows the WORA (write once, run anywhere) principle. Thus, once you compile a Java code, it can run on all platforms that support Java – you don’t need to recompile it. 

Java is a versatile programming language as it drives innovation and reduces time and costs significantly. Today, Java is the chosen language for IoT applications, enterprise applications, cloud computing, desktop GUI applications, web apps, mobile apps, embedded systems, Big Data systems, and AI applications.

Why Learn Java?

If you’re still wondering why to learn Java, here are five reasons why you should:

  1. It is extremely popular and commands a high salary

According to GitHub, Java is used by over 9 million developers worldwide, making it one of the most popular programming languages. Thanks to its diverse and multiple use cases, Java is always in high demand in the market. Consequently, companies readily pay high annual packages to hire experienced and qualified Java developers.

  1. It is a versatile OOP language

Java is an OOP language, meaning it includes the core OOP concepts like objects, classes, inheritance, encapsulation, and polymorphism. It is a platform-independent language, which means that Java is compatible with multiple platforms – you can run a bytecode on any hardware featuring a compliant JVM. It is a versatile language because it supports dynamic coding, stores the code in an OOP format, and is highly secure.

  1. It comes with powerful tools

One of the most exciting things about learning and using Java is that it comes with a host of tools to help make software development smooth and seamless. Java libraries like java.lang, java.util, java.io, JHipster, Maven, Guava, etc., and IDEs like Eclipse, NetBeans, and IntelliJ IDEA, expand the functionality of Java significantly. Thanks to these nifty tools, tasks like debugging, automated refactoring, syntax highlighting, etc., become much more manageable. Learn more about Java frameworks.

  1. It has excellent documentation

Javadoc is the documentation generator for Java, and it uses the Java source code to generate API documentation in HTML format. By doing so, Javadoc ensures that Java code has excellent and easy-to-understand references, thereby allowing users to grasp Java code pretty easily.

  1. A large community backs it

Java boasts of having a large online community of Java developers and users of all levels beginner, advanced, and expert). So, if ever you get stuck while working on a Java project, you can always reach out to the Java community for help.
