renameTo
public boolean renameTo(File dest)Renames the file denoted by this abstract pathname.
Whether or not this method can move a file from one filesystem to another is platform-dependent. 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
