Java  is  high-level  object   oriented  programming  language  developed  by  sun  microsystem.  java originally  called  oak  then  renamed  as  java.  Java  is  object   oriented  programming  language  similar to  c  and  c++. Java  source  code  files  are  compiled  into  format  called  bytecode.  Java  code  can  run on  most  computer  because  java  interpreter  and  runtime  environments  knows  as  java  virtual machine (jvm).

Java  byte  code  can  also  converted  directly  into  machine  language  instructions  by  just-in-time compiler (JIT) .   Java  is  a  general  purpose  programming  language  with  a  number  of  features.  A small  java  application  called  java  applet.  Java  is  used  mainly  on  the  internet  and  uses  a  virtual machine.  The  most  common  java  programs  are  applications  and  applets.  Application  is  nothing but  programs.  Applets  are  similer  to  application,  but  they  don’t  run  standalone.
Java  oops(Object Oriented  Programs)
Java  is  object  oriented  programming  language. These  include  class,  method,  inheritance, encapsulation,  abstraction,  polymorphism  etc.  objects  is  collection  of  state  and  behavior.  Class  is blueprint  of  which  object   is  created.  Inheritance  provides  a  mechanism  for  organizing  and structuring  your  software.  Interface  is  connection  between  a  class  and  outside  world.
A  package  is a  namespace  that  organizes  set  of  related  classes  and  interfaces.  Encapsulation  is the  technique  of  making  field  in  a  class.  The  main  purpose  of  encapsulation  is  the  ability  to modify  to  implemented  code  without  breaking  the  code  of  other  who  use  our  code.  Features  of encapsulation  are  maintainability,  flexibility,  extensibility  to  our  code.  Polymorphism  means  ability to  take  more  than  one  form.

Java programming language was originally developed by Sun Microsystems, which was initiated by James Gosling and released in 1995 as core component of Sun Microsystems.s Java platform (Java 1.0 [J2SE]).
As of December 08 the latest release of the Java Standard Edition is 6 (J2SE). With the advancement of Java and its wide spread popularity, multiple configurations were built to suite various types of platforms. Ex: J2EE for Enterprise Applications, J2ME for Mobile Applications.
Sun Microsystems has renamed the new J2 versions as Java SE, Java EE and Java ME respectively. Java is guaranteed to be Write Once, Run Anywhere
Java is:
  • Object Oriented : In java everything is an Object. Java can be easily extended since it is based on the Object model.
  • Platform independent: Unlike many other programming languages including C and C++ when Java is compiled, it is not compiled into platform specific machine, rather into platform independent byte code. This byte code is distributed over the web and interpreted by virtual Machine (JVM) on whichever platform it is being run.
  • Simple :Java is designed to be easy to learn. If you understand the basic concept of OOP java would be easy to master.
  • Secure : With Java's secure feature it enables to develop virus-free, tamper-free systems. Authentication techniques are based on public-key encryption.
  • Architectural- neutral :Java compiler generates an architecture-neutral object file format which makes the compiled code to be executable on many processors, with the presence Java runtime system.
  • Portable :being architectural neutral and having no implementation dependent aspects of the specification makes Java portable. Compiler and Java is written in ANSI C with a clean portability boundary which is a POSIX subset.
  • Robust :Java makes an effort to eliminate error prone situations by emphasizing mainly on compile time error checking and runtime checking.
  • Multi-threaded : With Java's multi-threaded feature it is possible to write programs that can do many tasks simultaneously. This design feature allows developers to construct smoothly running interactive applications.
  • Interpreted :Java byte code is translated on the fly to native machine instructions and is not stored anywhere. The development process is more rapid and analytical since the linking is an incremental and light weight process.
  • High Performance: With the use of Just-In-Time compilers Java enables high performance.
  • Distributed :Java is designed for the distributed environment of the internet.
  • Dynamic : Java is considered to be more dynamic than C or C++ since it is designed to adapt to an evolving environment. Java programs can carry extensive amount of run-time information that can be used to verify and resolve accesses to objects on run-time.
