Must learn JAVA.

Java is a general-purpose, object-oriented programming language that was designed by James Gosling at Sun Microsystems in 1991. The compilation of the Java applications results in the bytecode that can be run on any platform using the Java Virtual Machine. Because of this, Java is also known as a WORA (write once, run anywhere) language.

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.

In modern times, Java is one of the most popular programming languages as it can be used to design customized applications that are light and fast and serve a variety of purposes.

1. Java’s Popularity and High Salary:

Java is one of the most popular languages in the world. It is used by some 9 million developers and it runs on around 7 billion devices worldwide according to Oracle blogs. Because of the high demand for Java, Java developers are also quite sought after and they hold some of the most high-paying jobs in the industry.

2. Java is Easy to Learn:

Java is quite easy to learn and can be understood in a short span of time as it has a syntax similar to English. 

3. Java has a Large Community:

There is a large online community of Java users ranging from beginner, advanced and even expert levels that are particularly helpful in case any support is required. Some of the online communities for learning purposes are StackOverflow, Java Forums, etc.

4. Java has Powerful Development Tools:

There are many Integrated development environments (IDE’s) in Java that provides various facilities for software development to programmers. Powerful Java IDE’s such as Eclipse, NetBeans, IntelliJ IDEA, etc. play a big role in the success of Java.

5. Java is Free of Cost:

One of the reasons Java is very popular among individual programmers is that it is available under the Oracle Binary Code License (BCL) free of charge. This means that Java is free for development and test environments, but for commercial purposes, a small fee is required.

6. Java is Platform Independent:

Java is platform independent as the Java source code is converted to byte code by the compiler which can then be executed on any platform using the Java Virtual Machine. Java is also known as a WORA (write once, run anywhere) language because it is platform independent.

7. Java is Versatile:

Java is very versatile as it is used for programming applications on the web, mobile, desktop, etc. using different platforms.

8. 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.

9. 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

10. 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.
