         // creates file in the system
         f.createNewFile();
         
         // createNewFile() is invoked
         System.out.println("createNewFile() method is invoked");
         
         // tries to delete the newly created file
         bool = f.delete();
         
         // print
         System.out.println("File deleted: "+bool);
