Java is one of the most fundamental programming languages that anyone can pick up. It is so simple; yet, the possibility of what you can develop using Java is infinite! Through this blog, I will be listing down the top ten reasons to learn Java.

So, let’s get started by understanding all the above points in descending order.

10. Easy and Open Source

At number 10, Java is extremely easy and open source. It supports FLOSS philosophy where you don’t have to pay a single penny to write codes in Java. So, what are the reasons that contribute to its simplicity? Java is:

Easy - Data Science Tutorial - Edureka

  • Concurrent: Easy to process your data parallelly
  • Platform Independent (WORA): Write once and run anywhere
  • Open Source: Create Java applications at absolutely no cost
  • Robust: Strong memory management
  • Interpreted
  • HighPerformance
  • Secured
  • Dynamic

Furthermore, Java has made our life easier by removing all the complexities, such as pointers, operator overloading as you see in C++, or any other programming language.

9. Java New Features

The release of Java 9, 10, and its features is a milestone in the Java ecosystem. I have picked up a few new Java 9 features, which I feel are worth knowing about. The very first is the Project Jigsaw. The main aim of this project is to introduce the concept of modularity, support for creating modules, and then apply the same to JDK.

Also, the REPL tool has been introduced. This makes it quite easy to try different features. Along with that, you also have Jshell scripting where you can actually write this in a single go and, thereby, makes it quite easy. These new additions to Java help you to write simple code and test them.

8. Java EE and Its Rich API

  • Coming to Java API, it has no issues with the compatibility, and it handles a wide set of procedures and functions.
  • Also, you’ll be impressed that, there are over 4,500 API available for developers.
  • It provides API for I/O, networking, utilities, XML parsing, DB connection, and almost everything!

You can go through the complete list of Java API’s that are associated as part of Java 10 here.

7. Resources and Community Support

Java, as a programming language, is omnipresent, which means that it is present everywhere, starting from your phone to your setup box to satellites as well.

So, there is a huge job opportunity, once you grasp Java completely.

Then, Java has a wonderful support community. Because of this, learning is not at all a problem with Java. You have numerous resources available online that can act as your perfect companion, along with a support community. You have multiple forums, where all the doubts or errors related to Java are answered.

6. Java Applications

Well as I have mentioned above, Java is everywhere and it has an ocean of opportunities!

Now, let me take you through some of the technologies which make use of Java. Here I have selected some of the influenced domains which use Java.

  • Develop a web application and its popular frameworks (Spring, hibernate etc.)
  • Java is used in Android APP development
  • Java is used to test your web application using various automation testing tool, for example,  Selenium and QTP which are used to automate web applications and perform testing using Java.
  • Big data technology: Hadoop MapReduce framework is written in Java
  • Used in scientific and research communities to handle a huge amount of data

5. Java Development Tools

Now, you have many powerful development tools that you can do Java programming.

Some of the popular Java development tools are:

  1. Netbeans

  2. IntelliJ

  3. Eclipse

  4. Android Studio

All of the above tools not only help you in the code writing process, but they also offer a high-level debugging to the programmers.

4. Java Is Everywhere

Java is all over the place; it’s on the desktop; it’s on mobile; it's everywhere! Here, I have listed a few departments where Java has been explicitly used:

CompaniesUsingJava - top 10 reasons to learn java - Edureka

  • Banking: To deal with transaction management
  • Information Technology: Solve implementation dependencies, and this is the domain that hires most of the Java developers.
  • Stock market: To write algorithms as to which company they should invest in
  • Financial services: Java is used in server-side applications

So, it is not limited to just one domain! Also, it is being used by many big giants, such as Google, Philips, CapitalOne, Accenture, Uber, and many more.

So, you can be completely assured that Java is not going anywhere, anytime soon!

3. OOP Language

Most popular programming languages, like Java, C++, C#, Ruby, etc., follow an object-oriented programming paradigm.

Object Oriented programming is a programming style that is associated with the concepts such as:

  1. Classes

  2. Objects

  3. Inheritance

  4. Encapsulation

  5. Polymorphism

An object-based application in Java is based on declaring classes, creating objects from them, and the interactions between these objects. Hence, this is why Java is classified as an object-oriented programming language — the concepts of Java are highly relatable.

2. Portable and Versatile

Java is extremely portable, as well as a versatile language. By portable, I mean Java can be used across various platforms. Being an open source programming language, it is platform independent across OS. As its famous tagline says “Write Once and Run Anywhere." You can run Java bytecode on any hardware that has a compliant JVM. For example, you can simply write your code or create Java applications in a Windows environment, and then, run on any other environment — let’s say Linux!

Next, Java is also said to be one of the most versatile languages. Now, there are many reasons behind it. First of all, it has dynamic coding. All the codes are organized and stored in an object-oriented format known as classes. Then, it is highly secured. Next, it can easily work with different resources across a network. This makes Java network-concentric and a language that is not going out of the date anytime soon.

Next, coming to the last-but-not-the-least is Java’s popularity and high SALARY!

1. Java’s Popularity and High Salary

Java developers are the ones who acquire high paying jobs in the industry. The average Java developer earns around $110,000 per year in the United States.

Apart from this, you can refer this TIOBE programming index for all the present trending programming languages.

So, here you can see how Java has dominated this field from the early 2000’s to present 2018. This, in itself, should give you an idea of how popular Java is and how widely it is being used in the industry.

So, these were my top ten reasons to learn Java. If you have any other reason in your mind, you can mention it in the comment section below.
