Introduction
IDEs
Eclipse
Demo
Wrapup
What’s an IDE?
• What does IDE stand for?
• Integrated Development
Environment
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! 
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
The Eclipse Project
– “…is an open source software development
project dedicated to providing a robust, fullfeatured, 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 notfor-profit Corporation—All technology will
remain openly available and royalty-free
Eclipse Platform
• Available At:
– http://www.eclipse.org
• Is Cross Platform…
– Windows
– Linux
– OS X (Carbon)
– Solaris
– AIX
– HP-UX
– Java source
Eclipse Platform
• Composed of 3
subprojects
– Platform
– JDT (Java
Development Tools)
– PDE (Plug in
Development
Environment)
Platform
JDT
PDE
Eclipse Platform
• Provides the core frameworks and
services
– Ant Integration
– CVS
– Generic Debug Framework
– Text Editor Framework
– UI – Overall Platform L&F
– Others…
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)
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
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…)
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)
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…
