Java Power

Now, this is the world of competition, and technology plays an important role in the betterment of life on earth. If we look in to the future, technology will be the power and human brains are the driving forces behind that. Programming will be the major aspect of every technology.

JAVA is much ahead of all of its counterpart technologies. Its flexibility is its power.

There were five primary goals in the creation of the Java language:
  1. It should use the Object Oriented Programming methodology.
  2. It should allow the same program to be executed on multiple Operating Systems
  3. It should contain built-in support for using Computer Networks
  4. It should be designed to execute code from Remote Source securely.
  5. It should be easy to use by selecting what were considered the good parts of other object-oriented languages.
Java is a object oriented programming language originally developed by Sun Microsystems and released in 1995 as a core component of Sun Microsystems Java Platform. The language derives much of its syntax from C and C++ but has a simpler Object Model and fewer low-level facilities. Java applications are typically compiled to byte code that can run on any Java Virtual Machine (JVM) regardless of Computer Architecture.
The original and reference implementation Java compilers, virtual machines, and class libraries were developed by Sun from 1995. As of May 2007, in compliance with the specifications of the Java Community Process, Sun made available most of their Java technologies as free software under the GNU General Public License. Others have also developed alternative implementations of these Sun technologies, such as the GNU Compiler for Java and GNU Classpath.
Sun has defined three platforms targeting different application environments and segmented many of its APIs so that they belong to one of the platforms. The platforms are:
  • Java ME i.e. Java Platform, Micro Edition — targeting environments with limited resources,
  • Java SE i.e. Java Platform, Standard Edition — targeting workstation environments, and
  • Java EE i.e. Java Platform, Enterprise Edition — targeting large distributed enterprise or Internet environments.
