If you use the context menu on a project to inspect 
the project&#146;s properties, the '''Java Build Path''' page
will have a field for the '''Default output folder'''. The initial 
value is the <tt>bin</tt> directory directly under your project.
Similarly, the '''Source''' tab provides access to the location of 
your source input folder(s).



The Java perspective filters out the output folder from the 
Package Explorer. If you like, you can use the
Navigator view to browse the output folder.
