WHAT JAVA IS ? 1. Programming language introduced by Sun Microsystems in November 1995. 2. Java is a platform independent language and works on the principle ¡°Write Once, Run Everywhere, Any Time, and Forever¡± 3
Features Of Java 1. Object-Oriented Language-no coding outside of class. 2. Platform independent Language-use code on any os. 3. Used To Build Programs That Can Work On The Internet. 4. Used To Program Consumer Devices And Accessories Such As Cellular-Phones. 5. Secure-due to byte code. 4
JAVA PROGRAM APPLICATION APPLET STAND-ALONE DISTRIBUTED 5
1) Java application is further divided into two parts: a) Stand-alone:- In it, we can access the resource localy and we can¡¯t share the resources as the system is not available on the network. b) Distributed:- In it, we can access the resources within a limited area. 2) An applet is a java program which is used to access the resources remotely .To execute an applet we need a software WEB-BROWSER so that we can interact with a network over a communication path. 6
JDBC ? JDBC is the JAVA API that provides the facility to connect the JAVA APPLICATION with the Database . ? The JDBC classes are contained in the Java package java.sql and javax.sql package. ? JDBC drivers are available for most DBMS products: ? http://java.sun.com/products/jdbc 7
JDBC Components 8
JAVA SERVLETS ? A servlet acts as an intermediary between the client and the server. ? As servlet modules run on the server, they can receive and respond to requests made by the client. ? Servlets are generally used to create Dynamic HTML pages . 9
JAVA SERVER PAGES ? Servlets and JSP both are complimentary API¡¯s both providing a means of generating dynamic web client . ? JSP contains a mixture of HTML , JAVA-Script , Jsp Elements . ? JSP is the easiest way to write Servlet . ? Jsp pages are translated into servlets ,then servlets are compiled and at request time this compiled Servlet is executed. 10
