The following test case shows the JDK1.1beta3's failure to delete a
     directory if the directory has files in it. If it is compiled under
     JDK1.1beta3, it fails to delete. If it is compiled under
     JDK1.0, it deletes a directory including any files it has in it which is
     what delete should do.


import java.io.*;

class DeleteBug {
     DeleteBug() {

     public static void main(String args[]) {
          File a_Directory = new File("a_test_directory");
          a_Directory.delete();
     }
}
