Best 10 Reasons Why You Should Learn Java

Top 10 Reasons To Learn Java

Java is one of the most fundamental programming languages that anyone can pick up. It is so simple at the same time, the possibility of what you can develop using Java, is infinite! This is what makes Java the most widely used language in the industry today with Java Certification being a key skill that employers constantly look out for. Through this blog, I will be listing down the top 10 reasons to learn Java.

1. Java’s Popularity & High Salary
2. Java is Portable & Versatile
3. Java is an Object Oriented Programming Language
4. Demand: Java is everywhere
5. Java Development Tools
6. Java Applications
7. Tons of resources & Community Support
8. Java EE & its rich API
9. Java New Features
10. Java is easy & Open Source

Let’s get started by understanding all the above points in the reverse order.

10. Java is Easy & 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: 

• 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
• High Performance
• 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 Java9 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, REPL tool has been introduced which 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 making it quite easy.

So these new additions to Java help you to write simple code and test them up. 

8. Java EE & its Rich API

Now the reason API is quite popular, it becomes very easy for a programmer to build an application as well as use different technologies without actually knowing how their internal implementation works out.

• 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. Tons of Resources & Community Support

Java as a programming language is Omnipresent, which means 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. So 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 web application & 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. Ex: Selenium, QTP which is used to automate web applications and perform testing using Java.
• Big Data technology: Hadoop MapReduce framework is written in Java
• Used in Scientific & Research Communities to handle a huge amount of data

5. Java Development Tools

 

Now you have many powerful development tools in which 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 it also offers 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, and everywhere! Here I have listed down few departments where Java has been explicitly used:

• 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 soon!

3. Java is an OOPS Language

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

Object Oriented programming is a programming style which 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 interaction between these objects. Hence, Java Being an Object Oriented Programming language, the concepts of Java are highly relatable.

2. Portable & 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. Example: you can simply write your code or create Java applications in a Windows environment and run on any other environment, let’s say Linux etc.

Next, Java is said as 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 which is not going out of the date anytime soon.

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

1. Java’s Popularity & 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 10 reasons to learn Java. If you have any other reason in your mind, you can mention it in the comment section.

Learning by Doing: How to Learn Java Basics by Building Your Own Project

Java is not the hardest language to start with. So, it becomes way popular among novice developers joining the ranks of Java coders every single day. If you are reading this blog post, you might be interested in learning Java.

Java is widely used across industry, and especially in the area of Enterprise software, which results in many high paying job opportunities and makes this programming language a common language for newbies. A general promotion of it within colleges and other institutions providing a formal Computer Science education also contributes to its popularity.

However, these are not the only advantages of Java — among other things, it allows you to adopt good practices and makes it way easier to learn other languages in the future. And with no doubt, you can easily learn it if you’re following the right approach. In this post, I am going to share some of them with you.

The Importance of Practice in Programming

Beyond all doubt, practice is important and valuable. But, before we get to the advantages of hands-on experience, I want to draw your attention to one essential thing I often tell my students.

New programmers who are just learning and start implementing things, without being supervised, often end up adapting bad practices. To avoid that, especially when you are making your first steps in programming, I recommend looking for a person who will supervise you and teach you. A strong mentorship with someone engaged in a serious project, as well as communication within the community in the form of sharing code and asking for feedback, is worth the effort. Similarly, when you are applying for your first job, you want to be looking for a company with a strong team and a good leader who would be keen on investing into your learning.

Now, let’s return to practical experience. Learning by doing is different from learning by passively consuming the information. To make sure we can use all the newly acquired technology, we should put our skills to test and write tons of code. The benefits of hands-on experience are almost endless.

Efficiency and Productivity

By practicing, you get a clear understanding of what programming is. Consequently, you start doing better with each new hands-on task, complete it faster, and thus become more productive.

Even if you are not working on real-world projects yet, it’s important to get used to having deadlines. They are inextricably linked to the programming process. My recommendation is to set up your own deadlines while practicing stage and follow them as closely as possible.

How to Install OpenJDK 11 on CentOS 8

What is OpenJDK?

OpenJDk or Open Java Development Kit is a free, open-source framework of the Java Platform, Standard Edition (or Java SE). It contains the virtual machine, the Java Class Library, and the Java compiler. The difference between the Oracle OpenJDK and Oracle JDK is that OpenJDK is a source code reference point for the open-source model. Simultaneously, the Oracle JDK is a continuation or advanced model of the OpenJDK, which is not open source and requires a license to use.

In this article, we will be installing OpenJDK on Centos 8.
