Java Programming Language

What is Java ?

      Java is a general-purpose computer-programming language developed in June 1991 by James Gosling a former computer scientist with Sun Microsystems.

Java programming is used to produce software for multiple platforms ( Windows, Linux, Mac OS , etc).Java derives much of its syntax from the C and C++ programming languages. There are lots of applications and websites that will not work unless you have Java installed and more are created everyday.
                  


    Why is it called Java? 
        In 1991, Sun Microsystems had a requirement, to prepare new programming language used to develop software for electronic devices like TV Switch boxes, Remote Controller, etc. Initially James Gosling named Java as Oak ( It is a tree name ),
Oak Tree
but Sun Microsystems rejected Oak because already a programming language is existed with name Oak. Later it was renamed Java ( Java is coffee name and it is an island of Indonesia where Java Coffee plants were grown. ).


Why Java Programming ?

  • Java is a platform independent, when a programmer writes a Java application, the complied code(known as bytecode) runs on most operating systems(OS), including Windows, Linux, Mac OS.                                                                                                       
  • Java is Simple programming language. If any programming language take  
  1. Less Execution Time.
  2. Less Memory Utilisation.
  3. Less Power Consumption, then it is called simple programming language.
  • Java is tight coded programming language means small length code.
In C

    In Java

  • Java programming is Architectural Neutral.
  • It is Object Oriented Programming language.

Where Java is Used ?

      Java is the most popular language in today's world billion of devices running on a Java platform.
  • Desktop GUI Application : GUI Applications like
  • Scientific Application : Java supports to scientific application development, because of its security powerful, robustness features, much scientific application based on Java technology like MATLAB.
  • Enterprise Application : Java is the most secure language that is a reason most of the Banking Applications developed on Java platform.
  • Web Application : Java is used to develop web application also to support the java has provided JSP, Servlet, Structs, Spring, Hibernate.
  • Mobile Application : A mobile application can easily developed with the help of Java. In today's world, every phone has android OS which is based on Java and we also have java mobile phones.

Computer : Computer is an electronic device that is designed to work with Information. The term computer is derived from the Latin term ‘computare’, this means to calculate or programmable machine. Computer can not do anything without a Program.(Ex : PC, Laptop, Smartphones etc,.) Programming : Programming is the process of creating a set of instructions that tell a computer how to perform a task. Language : Language is the normal way humans communicate and  people use to express thoughts and feelings to each other. Only humans use language, though other animals communicate through other means. Human language has syntax, a set of rules for connecting words together to make statements and questions. What is Computer Programming Language?           A programming language is a vocabulary and set of grammatical rules for instructing a computer or computing device to perform specific tasks.A computer can understand binary language ( i.e., 0's and 1's ) only,but t

C Programming Language :           What is C ? C is a  Computer Programming Language. C was originally developed by Dennis Ritchie between 1972 and 1973 at Bell Labs. Dennis Ritchie The C programming language is a popular and widely used programming language for creating computer programs. C is what is called a compiled language . This means that once you write your C program, you must run it through a C compiler to turn your program into an executable that the computer can run (execute) .     Why C Programming? C is the mother of all programming languages and it is written in very simple and effective way. C is the best programming language today is still the fact that it simply powers everything. From your phone to your Wifi , no other language provides the level of hardware interaction with the practicality of a concise and expressive syntax. Sample C Program It is easier than Assembler language , much easier than Machine code and allows alm
