Java - Basics Information

Java - Basics Information

     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 '

               Java platform(Java 1.0[J2SE}).

             



               The latest release of the Java Standard Edition is Java SE 8. with the advancement of Java 

                and its widespread popularity, multiple configurations were built to suit various types of 

               platforms. For example: J2EE for Enterprise Application, J2ME, for Mobile Applications.

               The new  J2 version were renamed as Java EE, and Java ME respectively. Java is 

               guaranteed to be Write One, 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 language including C      and  C++, when Java is compiled, it is not compiled into platform specific machine    rather into platform independent byte code.                                                                                                                                                                                                                    
      • Simple: Java is designed to be easy to learn. If you understand the basic concept        of OOP Java, it 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.                                   
      • Architecture-neutral: Java compiler generates an architecture -neutral object         file format, which makes the compiled code executable on many processors, with    the presence of Java runtime system.                                                                                  
      • portable: Being architecture-neutral and having no implementation dependent        aspects of the specification makes Java portable. compiler in 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.                                             

      • multithreaded: with Java's multithreaded feature it is possible to write programs    that can perform many tasks simultaneously. This design feature allows the                developers to construct interactive applications that can run smoothly.                                  
      • 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.
