Changing a file name, without rewrite it

Question

I am trying to write a code that just changes the file name without reading and writing it with a different name, is there any built in function for that? I tried to search for

and if not, the best way would be rewriting it with a new name?

This question appears to be off-topic because it doesn't demonstrate a minimal understanding of the problem being solved. — Maroun, Jan 31 '14 at 11:37
sorry gor the idiotic question, i was looking for a renameTo function — user3256396, Jan 31 '14 at 11:41
That's not idiotic question. It's a valid question, but a minimal research efforts would have gave you the answer quickly. — Maroun, Jan 31 '14 at 11:42

How about the File.renameTo(File dest) function?

Try:

new File("MyFile.txt").renameTo(new File("MyNewFile.txt"));

renameTo

public boolean renameTo(File dest)

Renames the file denoted by this abstract pathname.

Many aspects of the behavior of this method are inherently platform-dependent: The rename operation might not be able to move a file from one filesystem to another, it might not be atomic, and it might not succeed if a file with the destination abstract pathname already exists. The return value should always be checked to make sure that the rename operation was successful.

Parameters: dest - The new abstract pathname for the named file

Returns: true if and only if the renaming succeeded; false otherwise

Throws: SecurityException - If a security manager exists and its SecurityManager.checkWrite(java.lang.String) method denies write access to either the old or new pathnames NullPointerException - If parameter dest is null
