// illustration of the class java.io.File:  prints out the names of all
// files in the directory from which the program was invoked

// the class File includes a broad range of methods relating to files
// and directories

// note, however, that there is no direct way to effect a UNIX chdir()
// system call; instead, to access a file in another directory, one must
// make a new instance of File for that file, i.e. do something like
//     
//        File AnotherF = new File(full path name of that file)
//
