JAVA

Java is a programming language that was developed by Sun Microsystems as a core component of Sun’s Java platform.

Java was released in the year 1995 and was designed to be used in the disturbed computer environment. (Disturbed computing refers to a condition when computer programming and data are spread out over more than a single computer, often over a network). Java is designed in a way that it incorporates the feel and look of the C++ language. However, it is much easier to use than C++ and its object model is far simpler. It is a free software and is available under the GNU General Public License. Most of the major operating systems like Microsoft; IBM etc. have incorporated the Java compilers in their products.

Uses and characteristics of Java

Java is used for the creation of complete applications that runs either on a single computer or distributed among clients and servers in a network. The portability and design of Java has made this tool one of the most widely used, almost ubiquitous programming language today. The programs created are portable in a network. The bytecode, which is capable of functioning anywhere in a network, has a Java Virtual Machine. The source program is compiled into the bytecode. The JVM interprets the bytecode into code that runs on the computer hardware. Java is object oriented. This implies that an object has the advantage of being part of class of objects and the code is common to the class. Platform Independence is one of its main characteristics which means that programs which are written in Java language must run similarly on any supported hardware/operating-system platform. The JIT (Just in Time) compilation technique translates the Java bytecode into the native code when the program is run. The more advanced VMs utilize dynamic recompilation in which the behavior of the program is analyzed by the VM. The recompilation and optimization of the critical parts of the program is then done. JIT compilation and dynamic recompilation allow Java programs to take advantage of the speed of native code without losing portability. Another technique termed as the static compilation refers to compiling directly into native code like a more traditional compiler. The static java compilers like GCJ translate the java language code to native object code; thereby eliminating the bytecode stage. This results in better performance compared to interpretation while compromising on the aspect of portability.

Advantages of Java

Java is fairly easy to learn and has significant advantages over other environments and languages thereby making it ideal option for any programming task. Moreover as compared to other programming languages, Java is designed to be user friendly and is fairly easy to compile, write and debug. Since Java is object oriented; it enables the user to create modular programs and reusable code. The best part is that Java is platform independent and can easily be moved from one computer system to the other.

Outsourcing Java Requirements

By outsourcing Java requirements; companies or individuals can gain access and explore world class capabilities and expertise. Moreover, they get to acquire a competitive advantage as well as get quality work delivered within stipulated time frames and budgets.
