10 Reasons to Learn Java Programming Language and Why Java is Best

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.

Many computer science graduates often ask me which is the best programming language to start with? Which language should I learn to begin with? Shall I learn Java? Or shall I start with Python, etc.?

Well, it depends upon the definition of your best programming language; if it's popularity, then obviously Java outscore everyone, even C, which is there for almost 50 years.

If it in terms of Job opportunities, again, Java outscore everyone. You can get tons of Jobs opportunity by learning Java programming language; you can develop core Java-based server-side applications, J2EE web and enterprise applications, and can even go for Android-based mobile application development.

So if you are not coming from C and C++ background and want to learn your first programming language, I will suggest choosing Java.


Btw, if you have already made your mind on learning Java and just looking for the best resource to start with, then I suggest you join The Complete Java Master Class on Udemy. One of the most up-to-date and comprehensive course to learn Java. It was recently updated for Java 11 as well. 

Why you should learn Java Programming Language


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.


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.



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.



5) Great collection of Open Source libraries


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.



7) Java is FREE

People like FREE things, Don't you? So if a programmer wants to learn a programming language or an organization wants to use technology, COST is an important factor. Since Java is free from the start, i.e., you don't need to pay anything to create Java application.


The availability of Java programmers is another big thing, which makes an organization choose Java for there strategic development.

8) Excellent documentation support - Javadocs

When I first saw Javadoc, I was amazed. It's a great piece of documentation, which tells a lot of things about Java API. I think without Javadoc documentation, Java wouldn't be as popular, and it's one of the main reasons, Why I believe Java is the best programming language.

Not everyone has time and intention to look at the code to learn what a method does or how to use a class. Javadoc made learning easy and provide an excellent reference while coding in Java.

9) 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.

10) Java is Everywhere

Yes, Java is everywhere, it's on the desktop, it's on mobile, it's on the card, almost everywhere and so is Java programmers. I think Java programmers outnumber any other programming language professional.

Though I don't have any data to back this up, it's based on experience. This vast availability of Java programmers is another reason why organizations prefer to choose Java for new development than any other programming language.

Having said that, programming is a massive field, and if you look at C and UNIX, which is still surviving and even stronger enough to live another 20 years, Java also falls in the same league.


Also, OOP is one of the best programming paradigms, and as long as it will be there, Java will remain solid.

How to Learn Java Programming from Scratch

Now, if you decide to learn Java programming, here are a couple of resources, which you can take a look at. I personally suggest joining an online course to start with and then picking a book, because they are almost always well written by authorities in the subject matter and catered for beginners.

To start with, I recommend joining The Complete Java Master Class at Udemy. You can buy this course on just under $10 on Udemy's flash sale, which they run, I think every month.

How to learn Java programming from Scratch



If you can afford it, then this is the best course to learn Java online. To be honest, it's dirt cheap, even one day Java class cost around $100 in developing countries, forget about development country. You can't get a comprehensive Java course less expensive than this.



The content is still valid, and Java Fundamentals has not changed, but I strongly suggest every programmer start with the latest Java version. Java 8 or Java 9 and on that parameter Modern Java in Action is currently the best book to learn Java.


You can also take a look at official Java tutorials offered by Oracle. These tutorials are both comprehensive, up-to-date, and covered almost all crucial details of Java programming language. Further, you can use Google along with your learning.

If you need to understand a particular concept, term, or any issue with Java, Google can point you to a specific resource. There are lots of blogs, tutorial sites, and free video tutorials on the internet to learn Java programming.

I have also created The Complete Java Developer RoadMap to take you from beginner to the professional Java developer. That roadmap includes everything a Java programmer needs to learn like topics, tools, technologies, and libraries.

Few More Java Resources you  may like

Thanks for reading this article so far. If you like Java Programming language, then please share it with your friends and colleagues. If you have any questions or doubts about learning Java, then please drop a note.

P. S. - If you need more choices, particularly free online training courses to learn Java programming then you can also take a look at this list of free Java courses that contains a lot of free Java courses from sites like Udemy, Coursera, and others.

Gee... I don't even know where to start here. Let's start with facts you got wrong. Java won't break even the top 5 of most popular languages:
Rust: 83.5%
Python: 73.1%
TypeScript: 73.1%
Kotlin: 72.6%
WebAssembly: 69.5%
(Stack overflow 2019 poll)

Java is not providing more job opportunities than any other language there is, but Java shows weaknesses where other languages show strength. So if you want to dive into the back-end/Android development I would recommend C++. It may be more challenging, but also has a more rewarding outcome.

Reason 1: There are many languages that are easier to pick up than Java.

Reason 2: Most languages these days are Object oriented, even PHP went down that road. But some other languages give you the flexibility of functional programming where Java does not.

Reason 3 & 4: I give you that, Java comes with rich API which will not get utilized to 80% by many developers making it bloated and in need for tools like Eclipse to navigate it. The same way you need Visual Studio for C# development.

Reason 7: So are many other languages worth learning. Licenced languages are rather a niche these days and require on job training anyways.

Reason 9 & 10: A colleague of mine best described it as "lazy programming". Where you don't have consider the strength and weaknesses of a particular system, building off that, but rather use the cookie cutter method losing performance and reliability.

And now... let me tell you a little about Java from my perspective:
Java has some popularity despite all the security issues that came up over the years for two reasons. First colleges keep teaching it for whatever reason that, setting young people on that path of struggle without giving them any alternatives, like it was done in my case. And second, is the lazy programming I've mentioned before. Wouldn't that be great if you can write it once and it would run on any system? Hell yeah! But, and that is a big but, if Java is not written with performance in mind, it becomes a resource hog. It has a terrible garbage collector that has been often patched, but kept producing memory leaks. And even if you compare well written applications in Java and C++ in benchmark test you will see that C++ will outperform Java. Apart from that, there are two "software"s that were leading the security vulnerability headlines in the 2000's for a decade: Flash and Java. security experts kept advising people do uninstall those 2 applications almost on monthly bases. Thankfully Flash is gone now.

I'm not gonna touch Java with a 10 foot pole in my lifetime or recommend it to beginners for these reasons:
- If you need more than 3 lines for "Hello world" print out it's an overkill
- Limited backwards compatibility where you can't update local client without breaking an application is more than annoying.
- Since back in the day it was Sun, now Oracle, have their iron grip on the design and development of the language and it's not being truly open source the fate of Java is set. Making it slow to adapt to ever faster progressing development around it.

The numbers you put for langauges doesn't seem alright, it may be this what StackOverflow developer wold love but that is not true picture for whole IT industry

Rust: 83.5%
Python: 73.1%
TypeScript: 73.1%
Kotlin: 72.6%
WebAssembly: 69.5%
