2. Overview • Introduction • IDEs • Eclipse • Demo • Wrapup

3. What’s an IDE? • What does IDE stand for? • Integrated Development Environment

4. Why Would I Want to Use One? • IDEs generally… • Save you time • Allow you to be more efficient • Remember class/member/package names for you • Present your classes in a meaningful and organized way • Allow you to debug code • Automate Repetitive Tasks • Make coding FUN! 

5. What IDEs are out there? • There are number of commercial and non-commercial IDEs available today • Microsoft .NET Visual Studio • JBuilder • Sun ONE Studio • XCode (Apple) • Emacs • Eclipse

6. The Eclipse Project • “…is an open source software development project dedicated to providing a robust, full-featured, commercial-quality, industry platform for the development of highly integrated tools. “ • Initially formed in November of 2001 from Industry Leaders • February 2, 2004: Eclipse reorg’d into an not-for-profit Corporation—All technology will remain openly available and royalty-free

7. Eclipse Platform • Available At: • http://www.eclipse.org • Is Cross Platform… • Windows • Linux • OS X (Carbon) • Solaris • AIX • HP-UX • Java source

8. Eclipse Platform • Composed of 3 subprojects • Platform • JDT (Java Development Tools) • PDE (Plug in Development Environment) Platform JDT PDE

9. Eclipse Platform • Provides the core frameworks and services • Ant Integration • CVS • Generic Debug Framework • Text Editor Framework • UI – Overall Platform L&F • Others…

10. PDE • Plug-In Development environment • Allows 3rd party developers to develop extensions to the Eclipse IDE • For example: • Integration with other tools (Perforce, Visual Source Safe, Rational) • Ease of Development (Struts, JSF, Swing, UML, EJBs) • Many others (RSS readers, other language editors, Google Search)

11. Java Development Tools • JDTs: • Add a full-featured Java IDE to the Eclipse Platform • Build Functionality • Index-based infrastructure that allows for searching, code assist, and refactoring • Several UI Features, including, • Package View • Type Hierarchy View • Java Outline View • Wizards for Creating Java Elements • Java Editor

12. Java Editor in Eclipse • A full featured Editor integrated into the Eclipse Plaform, providing: • Keyword highlighting • Syntax highlighting • Code Assist • Margin annotations for errors, break points, or search matches • Outliner that updates as you code • API help that shows information from the Javadoc • Import assistance that will create import declarations for you • Code formatting to allow for consistent and clean code • Refactoring Support • Debugger (more on this…)

13. Debugger • The debugger should be a developer’s favorite part of an IDE! • The Eclipse Debugger: • Can launch a JVM in Run or Debug mode • Attach to a running JVM • Run expressions on the fly • Has “scrapbook” pages for interactive code snippet evaluation • Dynamic Class Reloading (where supported by the JVM)

14. What does it look like? • It all depends on your Perspective… • Different Perspectives provide developers with different sets of Views • Views support the editors and provide the developers with ways to navigate through the projects • Eclipse comes pre-built with several perspectives… • Resource • Java • Java Browsing • Debug • CVS • Plug-In Dev • Team Synchronizing • Let’s take a look at the Workbench from the Java perspective…
