2. What is Java
Java stands for Just Another Virtual Accelerator.It is a
programming language, a platform and high level, robust,object-
oriented and secure programming language.
Design for easy web/internet application.
Write Once Run Anywhere(WORA).
3. ● The Java language was developed by James Gosling at Sun
Microsystem in 1995.
● Java being used pelvis for “Coffee”.
● Java start with green team. JavaTeam member also known as
Green Team.
● Initiated this project to develop a language for digital devices
like set-top boxes, televisions, etc. However, it was suited for
internet programming
History of Java
4. Features of Java
1. Java is very easy to learn and understand, and syntax is
simple, clean.
2. Java is a platform independent because Java is different from
other languages like C, C++, etc
3. Java is a object-oriented programming language.
4. Java is faster other traditional interpreted programming
languages because it’s byte code is "close" to native code.
5. Hello word program
/**
*A simple program
*/
Public class Hello Word
{
Public static void main(String args[])
{
System.out.print(“Hello”);
}
}
6. Why Java is Important
● Two reasons:
1. Trouble with c/c++ language is that they are not portable
and platform independent
2. Emergency of word wide web which demanded portable
program.
● Portability and security necessitated the invention of java
7. Characteristics of Java
● Java is simple
● Java is object oriented
● Java is distributed
● Java is interpreted
● Java is secure
● Java is portable
● Java is dynamic
● Java is multithreaded
● Java is robust
8. Agenda
Brief description of Java and overview of java language
● Solve a problem to demonstrate Java syntax
● Discuss coding issues and style via example
● Slides include more details on syntax
–may not cover everything in class, but you are expected to
know these
