Read this blog to know all this and much about starting a career in Java technology.
What is Java? how is it different from J2EE?
Java is a fast, secure, and reliable programming language. Most people use "Java" to address "core Java" or "JSE" (Java Standard Edition). Java is all around you, as it is quietly running in laptops, data centers, game consoles, scientific supercomputers, cell phones and also on the Internet or the World Wide Web.
J2EE is a platform-independent, Java-centric environment from Sun. This environment is used by developers to develop, build and deploy Web-based enterprise applications. It comprises of the following:
- A set of services
- Protocols to enable multi-tiered and web-based applications.
This computing platform was first released by Sun Microsystems back in the year 1995. Today it is so widely used that there are thousands of applications and websites which will fail until and unless you have Java installed on your system.

Did you know?
- The best part about Java is that it is opensource. Yes, you can download it for free!
- The latest version of Java can be easily accessed at java.com.
- Java 8 has crucial enhancements that can boost performance, stability, and security of all the Java applications which are currently running on your machine.

Evolution and a brief history of Java Developer
- James Gosling, Mike Sheridan, and Patrick Naughton (or the Green Team) kickstarted the Java language project in June 1991.
- It was named ‘Greentalk’ by James Gosling with file extension ‘.gt’.
- It was earlier known as ‘Oak Language’and was first used for embedded systems in electronic appliances like set-top boxes.
- In 1995, ‘Oak’ was renamed as ‘Java’.
- Sun released Java IO in 1996.
- By June 1997, Java became the #2 programming language in the world with 400,000 developers working on it.
- Java 2 was released as J2SE 1.2 in 1998.
- Sun announced J2SE, J2EE and J2ME in 1999.
- J2EE touched 1 million+ download milestone in 2001.
- Java was present inside 15 billion+ devices across the globe by 2004. There were 4 million java developers.
- By 2005, Java made a business of $100 billion, with 4.5 million global developers.
- In 2006, Java became open source.
- In 2007, there were 6 million Java developers.
- In 2011, Java 7 was released.
- In 2013, 9 million Java developers were present globally and every year, Java was downloaded 1 billion times!
- In 2014 Java 8 was released.
- After Java 7, Java 8 was the most popular environment in 2016.
Goals of a Developer who uses the Java Language Environment
Design requirements of Java programming are decided on the basis of the computing environment in which your software must be deployed. Java technology enables you to develop secure, high performance, and highly robust applications on multiple platforms that are spread across heterogeneous, distributed networks. Operating on multiple platforms invalidates the following:
- Binary distribution
- Patches, and so on.
In order to sustain, your Java programming language must be highly portable and dynamically adaptable. Below enlisted are a few objectives that you can accomplish with Java as your ‘weapon’!
- Java helps you to build a simple system that is easily programmable by most developers
- The language is English like and familiar.
- The object-oriented approach helps you to leverage modern software development methodologies so that your API can fit into distributed client-server applications.
- Your application becomes multithreaded, enabling high performance in applications.
- You can carry out multiple concurrent activities, with maximum portability!
All the above characteristics are found today in multiple software development platforms that are powered by Java. What’s more amazing is the way in which Java technology empowers its developers to produce flexible and powerful programming systems.

What does the future hold for Java Developer?
Slowly and steadily, Java is insinuating itself into the invisible cracks and crevices of the modern Operating system.
- JVM or Java virtual machines are common in next-gen gadgets such as smartphones, Kindle and Blu-ray disk players.
- Java is still buried in a whopping 2.6 billion cell phones, such as the$20 dumb phones, as well as high-end BlackBerrys and Android phones.
- Even the latest Ruby developers prefer JRuby, which is a Java-based implementation of the scripting language because JVM handles heavy loads better and unleashes multiple threads.
- Jython, or a Java-based clone of Python, is slowly gaining popularity these days.
- Grails binds scripting extensions like Groovy with database middleware Hibernate, for more dynamic options in code interpretation, as well as establishing direct links with Java APIs.
- JavaFX is a wild card. These graphics are comparable with Adobe's Flash as it’s computational engine supports the entire Java API. Despite the code is not as English-like as regular Java, Java programmers will enjoy learning it! After all, these new animation classes will pave way for highly interactive desktop tools.
- JavaCard is a powerful VM and API for tiny packages. It can interact directly with the Internet, which is making it very popular.
- A decent collection of apps available for Android phones is already present. Sun is also speculating a Java Store from where people can drag and drop an application onto their desktop.
- If the code (which is currently being written) for an Android OSfails to port easily to a Glassfish server or a Sony Blu-ray player, Java will get a brand-new opportunity to emerge hugely.
- Hence, in the near future, Java developers can write one app which will be compatible with Android phones, desktops and also Blu-ray players! That would be just so cool!
