Java was launched to the world in Circa May of 1995 and was produced by Sun Microsystems of SunOS, Solaris and Sun Kit fame. Java is a heavily obvious object oriented language that uses a virtual machine, namely the JVM (Java Virtual Machine) to run compiled bytecode that is interpreted by the JVM and such allows for code to be run on multiple platforms or more accurately platforms for which a compatible JVM is available.

Java is not a terse languages, sacrificing succinctness and nuance, to verboseness and clarification. This element of Java has polarised development a little, as some prefer to write code in a succinct, fast and elegant way, and that is something that is hard to achieve with Java. The JVM though runs bytecode not source code, as such, languages such as Jython (a derivative of Python) and Schema can be used to create Java Bytecode that will run in a JVM.

Java is perhaps one of the most obviously object oriented programming languages. And, this element of Java is where its real power lies. The Object Oriented features are quite explicit in nature, and as such most design patterns use Java as the bases for the implementation explanation of the design pattern. Java has definitely opened up and improved the Object Oriented paradigm. To get a good grasp on OO (Object Oriented) programming, it is wise to have Java in your Development bag of tricks.

Poised Solutions IT Practice doesn't make extensive use of Java internally outside of development for mobile phone systems. Java was originally intended as a digital TV language and after extensive marketing it is now a Jack of all Trade language, and whilst for some that is a strength, Poised Solutions prefers to take a master generalist approach to programming for internal systems and so often finds that another language is better suited for a technology task than Java. With that said, Poised Solutions does offer Java Development, though the rates are normally scaled up, and of course if you are looking to move from a Java based project to another language and system it is advantageous to know Java. As mentioned previously, Jython and Schema can also be used to create Java Bytecode and interface with legacy Java code, again a deep knowledge of Java is useful there even if it is not the implementation language.
