This package contains all the classes that normally reside in java.io. When JOS is distributed, they will migrate to java.io. The reason why they're in a different place now is that java.* classes can't be replaced easily in the standard JDK.
For an implementation see FilesystemCode; current status is: all JDK 1.0 parts implemented
- JDK 1.1 missing. (VolunteersWanted to add JDK 1.1 support!)
