[Gong James]

A directory can be created using a method from the class(es):
a) File
b) DataOutput
c) Directory
d) FileDescriptor
e) FileOutputStream

the given ans :a
i fill the ans line with :c
but i thought the class File has no effect on system.

[Michael Ernest]

Sure it does! The point to remember about the File class is that it does not create a new file when the constructor is called. Plus, there's no Directory class.

Hi Gong,
There is no directory class, and u can create a directory using File class but u can't change a directory ie. wandering btw directories.
Althoug Michael i think u can create a file using File class. In the following way -:
File f = new File();
f.createNewFile();
Correct me if i am wrong.

[Ernest Lee]

File Class does able to create file, it just cannot manipulate the content of created file though.
