Why is Java so important? and will it become obsolete?

Java is a language that almost any programmer loves. It is a language that possesses a certain charm like no other! Java was a language that started becoming popular in the mid-1990’s and became a leading programming language by the early 2000s. Java has its roots everywhere. with so much market share there arises a question. “will java ever become obsolete?” To get a detailed and unbiased opinion continue reading this post…


Java Logo

Java is a general-purpose computer-programming language that is concurrent, class-based, object-oriented, and specifically designed to have as few implementation dependencies as possible. Designed by James Gosling, Java is known as a “platform independent” language which means that once compiled, Java can run on any machine without being recompiled. This is the reason why Java is so popular. Another reason for Java being so popular is because it runs on the JVM a.k.a the “Java Virtual Machine”. This enables it to run on multiple platforms independent of the type of system architecture the machine uses. Java also finds a great use in the IT Department. It also serves as the backbone of many commercial digital products as well as backend services.

Some common places where Java is used are:

  • BigData(Hadoop)
  • Android Applications
  • Salesforce
  • Server-side processing, JSP, Servlet etc.
  • J2ME (Technology that allows Java to be programmed for mobile phones and PDA’s)
  • Games using LWJGL(Light Weight Java Game Library)
  • Java Web Applications using Applets
  • Software Tools
  • Client Side UI for banks and financial services

Advantages of Java


MEME: "Let's remove C++....and give them JAVA


  • Better memory management and garbage collection than C
  • Object Oriented
  • Platform Independent
  • Easy access to distributed computing
  • structured and strongly typed.
  • high security with concepts such as encapsulation.
  • multithreaded
  • large community of developers
  • Many frameworks are built on top of Java

Basically what I am trying to say is that Java is everywhere, for a language to dethrone java it needs to be better than Java in every way possible and also solve all its drawbacks. Which is very difficult.

The drawbacks of Java


MEME: "I tried to solve a problem with Java.....I now have a problem factory


The disadvantages of Java are:

  • Java compromises on performance by using the JVM. Java is significantly slower than the native languages such as C, C++
  • GUI apps using Swing and even JavaFX are often very ancient looking.
  • single paradigm language, there is only one way to write Java code for a specific output. it is not flexible like Python.
  • it consists of a lot of boilerplate code, i.e code that has to be written no matter what.
  • it is not beginner friendly, java should not be your first language. You are better off learning something like python.
  • Java is old, new languages such as Kotlin, Ruby on Rails, Python, R, Scala are way more superior than Java in many aspects.

Why can Java not be replaced that easily?


MEME: "Hey everyone uses kotlin instead of Java.....See nobody cares"


  • Large Community, Java has been a language that has been used since the mid-1990s and over the years it has gathered a very large community of developers.
  • Already established architecture, So many things are already built on top of Java that replacing Java would mean replacing all the current technology.
  • Important Frameworks, Java has been the beating heart of many popular frameworks such as Swing, Hadoop (BigData), JSP and more. without these, the IT sector cannot function.
  • IT Sectors like India would suffer loss, Indians love Java and many of them are experts at it! If Java is replaced it would mean that all the skills of these individuals would go to waste.
  • Resistance to change, many parts of the world do not want to change the already existing norms.
  • Wasted investment, Why would companies invest in new languages when Java works perfectly fine?

Why do we need a change in the first place?



Believe it or not, Java is getting old. It is no longer the first preferred language of many. Java feels ancient and featureless because other languages like Python have crushed java with its simplicity and ease of use. Many schools in India use java as the primary language for computer science. Java is not the language that beginners should use. If we are so dependent on Java and resistant to change we cannot create progress. There are many languages out there which have more potential than Java. Java can be replaced by another promising language namely, Kotlin. This language is loosely based on the core concepts of java but is much more modern and updated language with support for multi-paradigm programming along with the much lesser boilerplate code.


Our lives are indirectly dependent on Java. We have been using Java for such a long time that nearly everything has a bit of java embedded inside it. Currently, we are too dependent on Java to disband it all at once. It is beneficial for us to promote new and simple languages as an alternative to Java instead of claiming Java as the most superior. By encouraging competition we are making the entire community better and as the creators of java see the competition increasing they will update Java ASAP. This is better for the end user.

I would like to end this controversial post on a good note saying that Java is not going anywhere soon, Java is a language that is rooted in our lives and will probably never become obsolete”
