If programmers run the world, then Java programmers site at the centre of that power structure. Java is a general-purpose programming language which is designed to be easier to use than C++. Java is said to be a portable language, as the deployment of this language is simple to perform through a cross-platform compatible Java Virtual Machine (JVM). Android apps are also developed using this programming language since the Android operating system runs on a Java language environment.
In this write-up, we will discuss how much time span is required to learn Java Programming from scratch. We’ll cover two perspectives here: First, the one who has a fundamental knowledge of Object Oriented Programming. Second, the one who does not have any prior knowledge of OOPs. You must be wondering why I am using this term “OOP” repeatedly. Let me clear that Object Oriented Programming or OOPs, in short, is said to be the backbone of Java. Without any knowledge of OOPs, you cannot proceed to learn further.
Below, we’ll share how it will take approximately nine months if you don’t have any prior knowledge of OOPs, and merely a few months who already know the basics.
Let us find out the rating of Java out of 5 as per its characteristics-
Although Java has been criticized many times and many languages have tried to replace it as a better option, with the release of a better Java (Version-8) during 18th of March 2014, it will clearly continue to stay relevant and will be going strong, especially since it already has many mature tools and libraries that will not be easy to replace.
A programming language’s ability to stay relevant and survive also depends on whether the language is getting new blood, so clearly Java will continue to dominate in the years to come.
Mainly, Java was designed for the beginner-friendly. It assumes that the programmer is not that smart or careful, so programmers will be less likely to shoot themselves in the foot when coding Java applications.
Java is a high-level language, which means Java handles most of the complex details of the machine (computer) such as memory management, etc. Thus, you can focus on programming instead of worrying about the little details many consider both tedious and difficult.
Java is very stubborn and expansive, which means you need to write a lot of code trying to convince the language to build some feature. Thus, you may need to spend a lot of time coding before you can get a working app. This may be demotivating for coding beginners.
Java is a figural-typed language, which refers that your code should have to be checked for errors before it can be built into an app. This means errors will be easier to track down. Moreover, the languages that are typed statically are also strict as per the definitions of things, by this, you will have less strange and unexpected errors, which means your base of code will be as easier to maintain as it grows in size and complexity.
As a statically typed language, Java is said to be the faster language than other dynamically typed languages because things are more clearly defined. Therefore, when the app is running, your machine’s resources will not get wasted on checking the definition of something in your code.
Standard Java programs are now even more effective; thanks to the JIT (just in time) compilers and updated JVMs, because of this performance can be optimized in real time to help a Java program run faster. This is efficiently helpful as your application grows larger or requires handling more processes.
The size of the community is important because the larger a programming language community is, the more support you would be likely to get. As you forward your step into the programming world, you’ll soon understand how crucial support is, as the developer community is all about giving and receiving help. Furthermore, the larger a community, the more people will be building useful tools to make development in that particular language easier.
As of now, there are over 600 remarkable programming languages worldwide. So, with that milieu, let’s get into the details of the Java community size-
StackOverflow is a questions & answers programming site using which you will no doubt become intimate with as a beginner’s coder. Java has a wide community for both back-end web development and Android development.
At the meetup, you can simply network and learn from the fellow developers. Meetups often offer mentorship to those who want it as well. There are over 1.4k Java Meetup groups, totalling over 580k members worldwide. As per the programming languages, Java has the 4th largest meetup community.
Normally, the ecosystem of Java is quite wide and mature, so there are plenty of good tools and libraries that will greatly ease the process of developing Java apps and learning Java in general. You’ll find lots of like-minded, passionate programmers.
Java is the 3rd Most Demanded Skill on Angel list. Many tech experts such as Microsoft, Google or Amazon also use Java to develop the backend of their websites, and because Java has pretty good performance, a lot of startups who have reached the scaling point would integrate their applications with Java to power features that need to have good performance.
According to Indeed.com, Java developers are in high demand compared to other programmers.
There is plenty of short circuit learning process – to teach you a programming language. There are two aspects of getting a proper time period if you want to learn the Java programming language.
People having knowledge of OOPs
Object Oriented Programming (OOPs) is an integral part of the Java programming language. It includes the concepts of Encapsulation, Abstraction, Polymorphism, Message Passing, and Inheritance. People having fundamentals of OOPs will be able to learn Java easily and in a shorter span; because prerequisites are the same for all the programming languages.
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.
People who do not have knowledge of OOPs
OOPs became popular since it offers several benefits to the program designer and the user. Object-orientation contributes to the solutions of many problems associated with the development and quality of software products. Java is OOP language, you cannot run Java application without its style, but you can do in C++, it’s compiler still provide C style, which is a structured programming language.
There are plenty of books or online resources available that claim to teach Java in 21 days. I would say, don’t fall for it. You may still learn the syntax in 21 days, but that is not the same as learning a language. If you really want to understand the language you will need at least one year – to go from nothing to someone who can actually develop an entire application in Java. You do not need to have Mathematics or engineering background to become a software programmer in Java. Your background doesn’t really matter. What you need is dollops of common sense, a logical mind and the determination to work really hard.
The major factor on the basis of which the time depends is to what range do you want to learn java and more importantly to what end. If you want to learn Java to design web-applications, or you want to learn java to write desktop applications, or you want to learn java to design games or there are many other things which you can do after learning Java.
Learning programming is more than learning a foreign language. Let us break up core Java into different parts and try to guesstimate how much time you need to learn Java when you don’t have any prior experience of OOPs-
For a person with no prior programming experience, it is expected approximately 9 months, that is: 5+3+1 months to completely understand and write Java programs.
Some tips that would help you in your learning journey of Java:-
The best way to learn Java is to follow certain steps: learn terminology, practice, practice, oh wait, and more practice. Repetition is the key. Java is said to be the easiest programming languages. You may have to accept that you may not understand everything at the first time around and that’s truly all right. It’s also important to find out the best way you learn. The key is to be patient and understand that everyone learns differently. The primary fact to learn Java entails proficiency in theoretical knowledge as well as practical. Success lies in the amount of time invested to exercise the programming language, to make mistakes and to learn from those mistakes. May the coding Force be with you! Happy coding!
