Is Java Worth Learning in 2021

Is Java Worth Learning in 2021? Yes, it is worth learning Java in 2021 to update yourself on current marketing demand.

“According to Oracle Corporation, over 30,000 organizations had become Fusion Middleware customers, including over 35 of the world's 50 largest companies.

The other big player is IBM also using Java. There is more room for Java in the bank sector, financial sector, military, governments, army.”

Ever since the advent of Java on 23 January 1996, Java has grown to become one of the most widely used languages in the software development industry. There are a number of reasons for this, some of which are mentioned below.

Should I learn Java in 2021

Is Java Worth Learning: It is free and is considerably easier to learn than many other languages. For example, the process of garbage collection is automatic in Java and saves newbie programmers, a lot of hassle and frustration.

Java is a class-based, object-oriented programming language. This adds modularity for easier troubleshooting, code reusability through inheritance, and a lot of flexibility through polymorphism.

Java is a multithreaded language. Multithreading is a model that allows multiple threads to exist within the context of one process. These threads share the process's resources but are able to execute independently. This leads to lower resource consumption and better system utilisations and responsiveness.

Java is the native language for Android and is a go-to choice when it comes to app development.
Moreover, Java has an incredibly rich set of APIs, which further makes the development work easier and more fluid.
Java also has a fair share of applications in the field of big data. For example, Apache Hadoop, written in Java is a collection of open-source software utilities that provide a software framework for distributed storage and processing of big data using the MapReduce programming model.
Not only these, but Java also has a lot of applications in Blockchain and the development of client-server applications, which are used by large businesses around the world.
Ever since the inception of Java, it has been constantly evolving - with new features being added and old ones being enhanced with each new version. The latest version is Java 14, released in March 2020.
At last but not least, Java has a very supportive community of millions who come together to help newbies and professionals alike.
Although it is true that Java has lost some ground after the emergence of Python, Java still leads to sectors like company software and IT and services.

From established bigwigs like Google, Amazon, and Instagram to the hottest startups like Uber and Airbnb, tens of thousands of companies are still using Java technology in some form or another.

So, even though the final choice resides with you, it's a given that you won't regret learning Java in 2021.

Why Is Java Still Worth Learning In 2021

Java clearly remains a programming language that any developer should learn. For me, there are 10 main reasons for this detailed here: 10 Reasons Why Is Java Still Worth Learning In 2021

Java Can Do Everything
Java Is Easy To Learn
Java Is Widely Used In Companies
Java Has A Strong Community
Java Is Free
Java Is The Cobol Of The 21st Century
Java Is Also An Execution Platform With the JVM
Java Is Very Fast
Java Is Evolving Fast
Java Has A Rich Standard API

Conclusion

As we enter a new decade in 2021, Java is more than ever a programming language to learn. Whether as a first language or to broaden your programming skills, Java will bring you a lot and will be a significant asset to your career.

Is Java Worth Learning: Of course, Java is not always the most appropriate language for each domain in the computer industry. Nevertheless, Java has the advantage of being versatile while benefiting from an execution platform, the famous JVM, extremely powerful which will give you the possibility to create high-performance and scalable programs.

There are many reasons to learn a programming language but if you are talking about java then apart from technical, some reasons I can think of :

Unicode - java has Unicode means you can even make software in any language you want. For example: currently, I & my team is developing a website in java that would be available in English as well as in 2 Indian languages Hindi, Marathi.

Scope - learning JAVA would be beneficial for the future suppose you’ve learned it now you can go in mobile application development (ANDROID), Web development & Networking application.

Easy to learn- If you are familiar with some concepts of object-oriented programming or Cpp then JAVA would be damn easy to learn.

Support- According to Oracle the parent company of java says that java supports over 3 billion devices includes T.V., mobiles, washing machines, etc.

Software Giants Uses It- websites like :

Linkedin
eBay
Amazon
Google (uses java in Gmail at the back-end)

and many more are written in java. Startups like Travelkhana, TripAdvisor also heavily uses java . Hence there are many job opportunities for people who are good at java.

NOTE: if you are familiar with C++ or with OPP’s concept then my answer could help you to get started learning JAVA

How Long Does It Take to Learn Java for a Beginner

In my opinion, the real factor on which the time depends is to what extent do you want to learn java and more importantly to what end. Do you want to learn Java to design web applications, do you want to learn java to write desktop applications, do you want to learn java to design games or many other things which you can do after learning Java.

If you haven’t figured out these things, it’s alright you can figure these later by dipping your toes in everything but for each of these endeavors, you need to know core Java. So I’m going to try to break up core Java into different parts and try to guesstimate how much time on average is required for each part.

Part 1: Basic Programming: This is kind of a prerequisite for any programming language, if you ask me here you need to learn two things how to declare simple variables and just learn about one data structure, for now, that is array (Maybe for now you wouldn’t know what is a data structure and similar type of unfamiliar things will keep crawling up your way as you will start studying keep googling them and move on). The second thing you would need to know is how to loop, maybe this you can figure out later as well but I would prefer to keep it in the beginning. These loops can make you loopy in the beginning so it’s better to get them off the way. For this just pick any book or tutorial write your first java program and keep playing inside it. For this, I would say it will take you 4–5 days.

Part 2: Let’s move on to the object-oriented(ness) of Java and start learning about how you can use Java to program using object-oriented principles. Principles like Encapsulation, Inheritance, polymorphism, etc. Don’t just read these concepts, write example programs and think of how these principles can be applied in real-life scenarios. For this, I would say let’s give six days and a day off.

Part 3: Now we will move on to language basics that are things like syntax, data types, directory structures, essential classes, some concepts specific to Java, things like multi-threading, I/O etc (we will only go to the basics of these topics for now because in-depth studies of these topics alone can take days). Let’s book another week for this.

Part 4: Now let’s move on to the final topic that is collections, these are all different types of data structures with a specific purpose for each and everyone, they are there to store and manipulate data in user-specified ways and that would be going to be a large part of your programming efforts. Let’s give it another week.

Alright now you have learned how to write code in Java, now you need to know how to build things in Java. But either during building things or before that if you have time, learn more about data structures, design patterns, and also multi-threading because writing code is not really a challenge but writing efficient code that’s the real deal and these things will help you a lot in doing that.

A couple more things a lot of good tutorials are available in Java but a good book can also be really helpful, my suggestion would be to go for Head First Java. Also, don’t forget to use Java docs, people at Sun and Oracle have put real hard work into them.
