1. A well-defined directory (folder) structure:
   • Project directory, containing the DrJava project file and below it:
     • "src" -- the "source" directory which holds the "XXX.java" files
     • "classes" or "bin" directory which holds the compiled "XXX.class" files
2. The DrJava ("XXX.drjava") file, which holds the information about what files are in the project and other project-related data.

...

1. On your hard disk, create a folder to hold your project, e.g. "Lab09".   It's easiest to build the "src" and "classes" subdirectories at this point, or you can wait until step 4 below.
2. Click on Project/New
3. Browse to the project folder and save your DrJava project file with an appropriate name, e.g. "Lab09.drjava"  (DrJava will automatically add the file extension).
4.  In the Project Properties dialog that comes up, fill out the following fields.   You will need to click the "..." button to browse to and create the directories if they do not already exist.

   • Wiki Markup
     {{Project Root}} = {{\[project folder\]\src}}     e.g. "{{U:\Comp211\Lab09\src}}"

   • Wiki Markup
     {{Build Directory}} =  {{\[project folder\]\classes}}   e.g.  "{{U:\Comp211\Lab09\classes}}"

   • Wiki Markup
     {{Working Directory}} = {{\[project folder\]\classes}}   e.g.  "{{U:\Comp211\Lab09\classes}}"

5. Leave the rest of the fields blank for now and click "Ok"

To open a project, click on "Project/Open..." in DrJava and browse to your XXX.drjava project file.    If your computer is set up to do it, you might also be able to automatically open a DrJava project by simply double-clicking the project file.
