Java continues to be the most widely used single programming language today, edged out only by all scripting languages grouped together. But since Java the platform supports running applications written in various scripting languages, these numbers can be said to overlap. For instance, the Java virtual machine (JVM) will execute applications written in Java, Rexx, Ruby, JavaScript, Python, PHP Groovy, Clojure, and Scala. In many cases, Sun’s HotSpot JVM will run these applications better than their natively compiled counterparts because the just-in-time (JIT) compiler will re-optimize the compiled code over time according to execution characteristics.

The bottom line is that Java has remained the language and/or platform of choice for enterprise and web application development for many years, and it continues to grow. With Java freely available for development use, and its use as the language of choice in many college computer-science curriculums, Java will likely remain at the top for many years to come. This doesn’t mean we shouldn’t reexamine or even question Java’s future every so often, especially in light of Sun’s acquisition.

Java remains the premiere platform for building enterprise applications based on not only its solid foundation, but its language innovations that will allow developers to build faster, scalable systems quickly. By taking advantage of the flexibility that Java has always provided and adding a polyglot and poly-paradigm approach to software development, development teams can innovate inside an existing infrastructure with little or no changes to their infrastructure, making the sales pitch to management all the easier.

Pretty much sums up Java. In the corporate environment, companies are willing to pay for the new Java licenses because in the long run, it will turn out to be cheaper than introducing another language into the mix.

Java is one of the long dominant platforms for building enterprise solutions, has been steadily evolving since its first release in 1996, with a new major version coming every one to two years. Each of the six major releases brought language and platform innovations that continued to make better Java i.e. Java 7 seemed like it would be no exception.

Java is traditionally viewed as just a programming language, but it is more than that. Java consists of three parts: the programming language, the virtual machine and the class libraries. Java, the programming language, compiles down to bytecode, which is the machine code that the Java Virtual Machine (JVM) reads and executes at runtime. Java developers can take advantage of reusable libraries and APIs packaged with the JVM, also in bytecode.
