For many years, Java has gone on to maintain a top position in Programming Languages. It is listed third among the world’s most popular programming languages.

As of now, Java has the credit of working along with a highly active community.  It has been noted as a popular server-side language for many back-end development projects. This includes Machine Learning and Big Data projects along with Android and Web development.

Now, Should You Learn Java in 2021 ? I would ask , Why Not?

Java development has played a major role in the development of amazing products across the globe.

One of the topmost traits which makes Java development popular among other folks is that it is an object-oriented programming language.

11 reasons Why You Should Learn Java in 2021 !

1. Java’s Popularity and High Salary

Java is one of the most popular languages in the world. It is used by some 9 million developers and it runs on around 7 billion devices worldwide according to Oracle blogs. Because of the high demand for Java, Java developers are also quite sought after and they hold some of the most high-paying jobs in the industry. The average salary of a Java Developer lies between $47,169 to $106,610 per year.

2. Java is easy to Learn and Implement

The masterpiece in the world of object oriented programming is continuously evolving. Now, unlike other programming languages, Java did not make unrecognizable changes to its fundamentals. The basic object oriented features and principles of Java are maintained in the same way since the beginning.

All the advancements are done in the way by introducing new libraries and API’s, along with some new methods just to reduce the time consumed in programming. Java has fluent English like syntax with minimum characters, for example, gender x angle brackets, which makes it easy to read a Java program and learn it quickly.

Once a program is familiar with initial challenges like installing JDK, and setting up the path and understand how the class path works, it’s pretty easy to write a Java program downloading and setting up Java and Perfect World is really simple. Don’t you worry about that.

3. We can use Java Web Development for everything

For a long time, developers have been dependent on Java when they want to develop web and Android apps. Java’s case studies have broadened on to Data Science, IoT and Machine learning apps. Many programmers and developers wish to use Java for designing such similar apps since Java uses IntelliJ IDEA, Eclipse, NetBeans IDE and so on.

Nowadays, Java’s use cases have moved on to far and wide with high-level tools and packages available. Java is also found to be compatible on multiple platforms.

4. Java is Platform independent

The main reason that many developers and major IT companies adopted Java is because Java uses the principle that says write once and run anywhere. This would have been not possible if it did not have JVM aka Java Virtual Machine.

So Java virtual machine works in a simple but most effective way. All the code that you write in Java programming language is sent to the JVM before getting executed. Here, the JVM converts the programmer readable code into byte code and sense this byte code to the compiler or the interface rigor, and this byte code will be executed at the end.

So this process stands the same, regardless of any environment where the JVM is functioning in. So this makes Java completely platform independent.

5. An enormous community backs Java

The reason why Java is popular is owing to its active and supportive community. Java is known to be the second-largest solution in the Stack Overflow community. You have the freedom to rely upon the Java community when you want to get help while dealing with programming rut. Java also offers high-end community support.

Similar to Java, Android also helps you leverage the support of your extended community. This can help resolve any existing issues whenever it appears. The community can support like-minded developers when they want to grow their network in an extensive manner. The thriving community would share their knowledge with every developer who wants to extend their coding skillset to the next level.

With the Java community, you can lead your business in the right direction.
