JAVA
Java is a high-level programming language originally developed by Sun Microsystems and released in 1995. Java runs on a variety of platforms, such as Windows, Mac OS, and the various versions of UNIX. Java is an Object Oriented Language. As a language that has the Object Oriented feature Java supports the following fundamental concepts:
Ø Object Oriented : In java everything is an Object. Java can be easily extended since it is based on the Object model.
Ø 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.
Ø Secure : It enables to develop virus-free, tamper-free systems. Authentication techniques are based on public-key encryption.
Ø 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.
Ø Robust :Java makes an effort to eliminate error prone situations by emphasizing mainly on compile time error checking and runtime checking.
Ø High Performance: With the use of Just-In-Time compilers Java enables high performance.
Ø 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.
Ø Distributed :Java is designed for the distributed environment of the internet.
Ø Multi-threaded : It is possible to write programs that can do many tasks simultaneously. This design feature allows developers to construct smoothly running interactive applications.
Ø Simple :Java is designed to be easy to learn. If you understand the basic concept of OOP java would be easy to master.
