Introduction

• Prior to the beginning of the new millennium
  Java, a computer programming language became very
  popular in the world of software and web
  application right from its inception.
• James Gosling of Sun Microsystems in the year
  1995 developed Java whose syntax although quite
  similar to C and C sharp, has a less
  complicated object model and low level
  facilities.
• It was originally called Oak but later got
  its present name. From the first stable version
  the JDK 1.0.2, to Java SE 6 update 25, released
  on April 2011, it has undergone an array of
  versions. The latest of Java version is the Java
  7 or Dolphin which is its code name is expected
  to release on July 2011.

Why It Is Popular

• Code files of Java are compiled into byte
  codes which can then be interpreted or executed
  by an expert. Byte code can also be translated
  with the help of a Just in time compiler.
• If a program has been written in a certain
  programming language in a Windows XP environment,
  the same program will not run in a MAC OS.

5
Commenting Style With Java

• Comments can be given in three different
  styles- a single line style with two slashes
  (//), a slash and an asterisk (/) which is
  called as the multiple line and asterisk slash
  (/) which is called the closed line comment.

Java is a Dynamic Language

• Java, a dynamic language has a considerable
  secured configuration and stable security system
  and enables restriction of file access. So far it
  has always given a very high rated performance.
• It uses Java virtual machines so the best
  part of Java is its portability which means any
  programme written in Java can be run in any
  computer with any hardware configuration.
• It manages and controls the memory through
  automatic garbage collector.

How To Overcome From Its Drawback

• But With all its plus points Java also has few
  drawbacks namely slow speed and less memory
  capacity than C. But its performance is
  significantly improving.
• The second drawback is that it lacks
  management of explicit memory. Moreover it cannot
  work with objects and numbers. And only memory
  allocation is possible, de-allocation of memory
  is not possible.
• To overcome its drawback of slow speed,
  Systronix has developed JStik, a micro
  controller. Java has various components. It uses
  a multi-layered built for connectivity of
  database and XMl files for writing codes and
  storing data.

Conclusion

• Initially it was used for computing devises
  which are small. But now it is used in cell
  phones, electronic commerce application, and MP3
  players. The games and services available in
  mobiles are with the help Java technology.
• The best way to learn Java for a beginner is
  to log on to the internet. One may also read
  books or join a computer teaching centre.
