Definition of Java?
Java is a high-level programming language developed by Sun Microsystems. When Java was created by Sun Microsystems in 1995 it was not for the Internet. Instead, the primary motivation was the need for a platform-independent language that could be used to create software to be embedded in various consumer electronic devices. This feature of platform independence made java very useful for the Internet where all kinds of machines are networked. Java expands the universe of objects that can be moved freely in cyberspace.
The History of Java Technology:-
Today, with technology such a part of our daily lives, we take it for granted that we can be connected and access applications and content anywhere, anytime. Because of Java, we expect digital devices to be smarter, more functional, and way more entertaining.
In the early 90s, extending the power of network computing to the activities of everyday life was a radical vision. In 1991, a small group of Sun engineers called the “Green Team” believed that the next wave in computing was the union of digital consumer devices and computers. Led by James Gosling, the team worked around the clock and created the programming language that would revolutionize our world – Java.
The Green Team demonstrated their new language with an interactive, handheld home entertainment controller that was originally targeted at the digital cable television industry. Unfortunately, the concept was much too advanced for the team at the time. But it was just right for the Internet, which was just starting to take off. In 1995, the team announced that the Netscape Navigator Internet browser would incorporate Java technology.
Today, Java not only permeates the Internet but also is the invisible force behind many of the applications and devices that power our day-to-day lives. From mobile phones to handheld devices, games, and navigation systems to e-business solutions, Java is everywhere!

Why Learn Java?
Java is one of the best programming languages created ever, and I am not saying this because I am a passionate Java developer, but Java has proved it in the last 20 years. Two decades is a big time for any Programming language, and Java has gained strength every passing day. Though there are times, when Java development slows down, but Java has responded well. Earlier with groundbreaking changes in the form of Enum, Generics, and Autoboxing in Java 5, performance improvement with Java 6, and Google’s choice of language for Android apps development, keeps Java as front line programming language.
If it is in terms of Job opportunities, again Java outscores everyone. You can get more Jobs opportunity by learning Java programming language, you can develop core Java-based server-side applications, J2EE web, and enterprise applications, and can even go for Android-based mobile application development.
Advantages of Java:-
1.Java offers higher cross-functionality and portability as programs written in one platform can run across desktops, mobiles, and embedded systems.
2.Java is easy to learn, simple, object-oriented, platform-independent, secure, robust, distributed, supports multithreading, and offers multimedia and network support.
3.Java is a Secure platform, thanks to its Virtual Machine. This is one of the primary reasons Companies worldwide are using this Language. So it’s here to stay.
