Java is one of the best programming languages created ever, and I am not saying this because I am a passionate Java developer, but Java has proved it in the last 20 years. Two decades is a big time for any Programming language, and Java has gained strength every passing day. Though there are times when Java development slows down, Java has responded well. Earlier with groundbreaking changes in the form of Enum, Generics, and Autoboxing in Java 5, performance improvement with Java 6, functional programming using the lambda expressions in Java 8, and Google's choice of language for Android apps development keeps Java as a front-line programming language.
Why You Must Consider Writing Software Applications in JAVA
1) Java is Easy to learn
Many would be surprised to see this one of the top reasons for learning Java or considering it as the best programming language, but it is. If you have a steep learning curve, it would be difficult to get productive in a short span of time, which is the case with most of the professional project.
Java has fluent English like syntax with minimum magic characters e.g., Generics angle brackets, which makes it easy to read Java program and learn quickly.
Once a programmer is familiar with initial hurdles with installing JDK and setting up PATH and understand How Classpath works, it's pretty easy to write a program in Java.
2) Java is an Object-Oriented Programming Language
Another reason, which made Java popular is that it's an Object Oriented Programming language. Developing an OOP application is much easier, and it also helps to keep system modular, flexible, and extensible.
Once you have knowledge of crucial OOP concepts like Abstraction, Encapsulation, Polymorphism, and Inheritance, you can use all those with Java. Java itself embodies many best practices and design patterns in its library.
Java is one of the few close to 100% OOP programming languages. Java also promotes the use of SOLID and Object-oriented design principles in the form of open source projects like Spring, which make sure your object dependency is managed well by using the Dependency Injection principle.
3) Java has Rich API
One more reason for Java programming language's huge success is its Rich API, and most importantly, it's highly visible because it comes with Java installation.
When I first started Java programming, I used to code Applets, and those days Applets provides excellent animation capability, which amazes new programmers like us, who are used to code in Turbo C++ editor.
Java provides API for I/O, networking, utilities, XML parsing, database connection, and almost everything. Whatever left is covered by open source libraries like Apache Commons, Google Guava, Jackson, Gson, Apache POI, and others.

4) Powerful development tools e.g., Eclipse, Netbeans
Believe it or not, Eclipse and Netbeans have played a huge role in making Java one of the best programming languages. Coding in IDE is a pleasure, especially if you have coded in DOS Editor or Notepad.
They not only help in code completion but also provides a powerful debugging capability, which is essential for real-world development. Integrated Development Environment (IDE) made Java development much more comfortable, faster, and fluent. It's easy to search, refactor, and read code using IDEs.
Apart from IDE, Java platform also has several other tools like Maven and ANT for building Java applications, Jenkins for Continuous Integration and delivery, decompilers, JConsole, Visual VM for monitoring Heap usage, etc.
5) Great collection of Open Source libraries
Open-source libraries ensure that Java should be used everywhere. Apache, Google, and other organization have contributed a lot of great libraries, which makes Java development easy, faster, and cost-effective.
There are frameworks like Spring, Struts, Maven, which ensures that Java development follows best practices of software craftsmanship, promotes the use of design patterns, and assisted Java developers in getting there job done.
I always recommend searching for functionality in Google before writing your own code. There is a good chance that it's already coded, tested, and available for ready to use.
6) Wonderful Community Support
A strong and thriving community is the biggest strength of Java programming language and platform. No matter how good a language is, it wouldn't survive if there is no community to support, help, and share their knowledge.
Java has been very lucky; it has lots of active forums, StackOverflow, open-source organizations, and several Java user groups to help everything.
There is the community to help beginners, advanced and even expert Java programmers. Java actually promotes taking and giving back to community habit. Lots of programmers, who use open source, contribute as a commiter, tester, etc.
Many Expert programmers provide advice FREE at various Java forums and StackOverflow. This is simply amazing and gives a lot of confidence to a newbie in Java.
7) Java is Platform Independent
In the 1990s, this was the main reason for Java's popularity. The idea of platform independence is great, and Java's tagline "write once run anywhere," and acronym "WORA" was enticing enough to attract lots of new development in Java.
This is still one of the reasons for Java being the best programming language, most Java applications are developed in the Windows environment and run on the Linux platform.
