1. Welcome To Eclipse

2. Basic Concepts Workspace – directory where your projects are stored –Projects grouping of related works –Resources generic term to represent projects, folders, or files Workbench – the IDE rich client –Features collection of plug-ins to implement an eclipse product –Plug-in provides some eclipse functionality

3. Workbench Perspectives –grouping of views and editors for a specific purpose Views –provide navigation or information Editors –provide a view for the sole purpose of editing key elements

4. Workbench Package Explorer Views Editor Area Views (typically outline based) Supporting Views

5. Java Perspective Lets walk thru and show –how to create a java project –how to creating a java class –how to use the auto complete –how to run our java program –how to debug our java program –how to test our java program with JUnit –how to set the preferences and settings

6. Slides to refresh your memory

7. Create a Java Project 1.File  New  Java Project 2.Follow the dialog screens answering the questions (call the project MyFirstProject)

8. Create a Java Class 1.Right click on the project and select new  class from the popup menu 2.Fill in the dialog Package: edu.cs205aa.student.learning Class: Factorial Select for the main method to be created.

9. Adding the Implementation Now we are already to add in the implementation for the new Factorial class Update the code

10. Creating a JUnit test 1.Right click on the class in the project explorer and add a JUnit test 2.Fill in the dialog for the test package: edu.cs205aa.student.learning.test 3.add the test code

11. Run the JUnit Test Run the JUnit test by selecting Run as JUnit Test The test failed … something is wrong we need to debug

12. Debug Java Code Add a breakpoint by right clicking on the left-hand column and “Toggling Breakpoint” Then run the debugger by Debug As  Junit Test Then you step thru the code and look at variable values, call stack, …

13. Finding the problem … Debugging the test we can determine the problem is we used an internal variable of int instead of long and we are loosing precision
