There are many reason to learn java and I discuss some of them.
Easy and Open Source
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
- HighPerformance
- Secured
- Dynamic
New Features Of Java
The release of Java 9, 10, and its features is a milestone in the Java ecosystem. I have picked up a few new Java 9 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, the REPL tool has been introduced. This 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, makes it quite easy. These new additions to Java help you to write simple code and test them.
Java EE and Its Rich API
Now, the reason API is quite popular is because 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!
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 a web application and 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, for example, Selenium and QTP which are used to automate web applications and perform testing using Java.
- Big data technology: Hadoop MapReduce framework is written in Java
- Used in scientific and research communities to handle a huge amount of data
Java Development Tools
Now, you have many powerful development tools that you can do Java programming. Some of the popular Java development tools are:
- Netbeans
- IntelliJ
- Eclipse
- Android Studio
All of the above tools not only help you in the code writing process, but they also offer a high-level debugging to the programmers.
Resources and Community Support
Java, as a programming language, is omnipresent, which means that 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. Because of this, 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.
Uses Of Java
Java is all over the place; it’s on the desktop; it’s on mobile; it’s everywhere! Here, I have listed a 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 there are also so many reason for why you can start learn java.
