Introduction to Java

               What is Java?                     

,

                         Java is the most broadly utilized programming language. It creates a secured, reliable and platform independent programming language. Which should be imperative and reflective.

Highlights of java

1              1.  Simple, Small and Familiar:

Java is simple because most of the features are derived from c and cpp. Java removes complexity because it does not uses the pointers.

Java is definitely not small but it is small in terms of coding and programming statements.

2             2.  Object Oriented Language:       

A programing language which supports the features like polymorphism, inheritance, Data hiding, Data abstraction, Encapsulation is called as an object oriented language.

3             3.  High performance:

Java programs are compiles to a portable intermediate code through a user defined class known as byte code. Because of this Java’s reusability is maximum and its execution speed is comparable with its native c and cpp. Java compiler convert the java code in o byte code and these byte code is executed by JVM (Java Virtual Machine) hence java programs and applications provide high performance on every platform.

4             4.  Platform Independent:

Java program written on one platform and can run on any other platform without need to recompile or any modifications.

  

5            5.  Multi-Threaded:

Multithreading means threading multiple threads at a time. Threads are used in network based applications.

6            6.  Interpreted and Compiled:

Java programs are compiles to a portable intermediate code through a user defined class known as byte code. Because of this Java’s reusability is maximum and its execution speed is comparable with its native c and cpp. Java compiler convert the java code in o byte code and these byte code is executed by JVM (Java Virtual Machine) hence java programs and applications provide high performance on every platform.

7            7.  Robust and secure (Easily executable):

Java is widely used in web servers and web pages. The ability to create the robust programs was gives a high priority during design a java. It performs compile time as well as runtime checking for datatype. Java is design with built-in tools called garbage collector, which reduces all the memory management problems for the programmers.

8             8.  Portability:

Java perform the portability because of its architecture neutrality. Source code may run on different hardware platforms to platform. This consistencies make the java platform portable on different platforms such as Windows, Unix, etc.        

                             So in next blog We see the exact coding of Java Programming.
