The evolution of java and its varied versions

  1. 1. Java Software Development<br />The Evolution of JAVA and Its Varied Versions<br />
  2. 2. Agenda<br />Introduction<br />Why it is popular<br />Java is a dynamic language<br />Conclusion<br />
  3. 3. Introduction<br /> 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. <br /> 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.<br /> 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.<br />
  4. 4. Why It Is Popular<br /> 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.<br /> 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. <br />
  5. 5. Commenting Style With Java<br /> 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.<br />
  6. 6. Java is a Dynamic Language<br />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.<br />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. <br /> It manages and controls the memory through automatic garbage collector.<br />
  7. 7. How To Overcome From Its Drawback <br />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. <br /> 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. <br />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.<br />
  8. 8. Conclusion<br /> 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. <br /> 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.<br />
