java introductionJava technology is a programming language that is used for meeting the objective of current challenges and opportunities in the present computing realm. Java is the high level ,third generation programming language, like C,PERL and many others.Java contains built in support for the world wise web. It is a platform for distributed computing and networking environments providing platform independent. secure and robust applications that can run on a verity of computers and devices. History of JavaThe evaluation of java platform and supporting technologies has proceeded at quite a rapid pace. Internet became popular at the time java was developed. People working on the internet were using different kind of PC'S. So need of a language that could run on any kind of platform. This leads to java's popularity and made it the most talked about language. java development began at sun Microsystems in 1991,the same year the concept of world wide web oriented.java's creator James Gosling, did not design java for the internet. His objective was to create a common development environment for consumer electronic devices. Which is easily portable from one device to another. thejava development team began by using C++ as their model, but later altered it so as to have simplified syntax, increased robustness, better security feature and greater portability across different operating system platform. Java architectureTo execute a java platform on a machine, you need certain working conditions. These are provide by the java run-time. The figure below shows the java architecture.suppose that the java source code is saved in a file called firstpr.java.the source file firstpr.java is compiled using the javac compiler and a class called firstpr.class is generated. | |||||||
