Introduction To Java Questions to be addressed Why would I use Java - PowerPoint PPT Presentation

Introduction To Java  Questions to be addressed  Why would I use Java for developing my applications?  How do I get started on developing Java applications?  What applications do I need to start developing?

Why Java?  Platform independence  Works on every operating system there is a JDK for. (One application for all platforms)  Mainly free  The JDK distribution is freely available, and there is no need to pay for any of the development tools which are commonly used.

Why Java?  Connects with several available database systems easily  JDBC drivers are available for many different database systems including  Oracle  MySQL  SQL Server 2005

Why Java?  A wide variety of applications.  GUI database tools such as client records systems, invoicing systems, et al.  Paint and graphics objects to build games or image manipulation applications.  Web applications using JSP pages.

How do I get started?  To work with Java you need these components  Java JDK  Java ME framework (to develop applications for mobile phones)  Java EE framework

Required tools http://java.sun.com/javase/downloads/index.jsp

Required Tools  Netbeans 6.0 contains all the libraries necessary to develop the various different programs supported by the Java framework

Other recommended tools  Eclipse IDE  Similar to the netbeans IDE, uses a plugin framework. Is widely accepted as an industry standard.  Oracle Jdeveloper  Excellent tool for fast JDBC Development, however is quite resource hungry.

Netbeans  The favoured IDE used by Sun  A good introductory tool written in Java for java development  Have mainly favoured netbeans for use in introductory courses to java...point for discussion?

Java SE Development  Java is an object-oriented language  Classes, methods and objects are the keywords here.  Supports full GUI development for standard applications.

GUI Application Development  In Netbeans 6.0 GUI development is vey simple.  In the following example, we will demonstrate an Lm to Euro converter Java Application using Netbeans 6.0

Web Application Development  The next example will be a simple JSP based web application, still within netbeans  Note the similarity in coding between a normal GUI application and the web application

Mobile Phone Development  The final example is the same application written to run on a mobile phone  Note that the mobile phone application also demonstrates a high level of commonality with the other platforms
