Java: valueOf vs copyValueOf

Question

What is the difference between valueOfand copyValueOf. I looked at GrepCode, only to find that both return the same.

copyValueOf:

Parameters : data - an array of characters.

Returns : A string containing the characters of an array of characters.

public static String copyValueOf (char data []) {return new String (data); }

valueOf:

Returns a string representation of the argument of the char array. The contents of the character array are copied; subsequent modification of the character array does not affect the returned string.

Parameters : character array data.

Returns : A string containing the characters of an array of characters.

public static String valueOf (char data []) {return new String (data); }

So, if both do the same thing, then why is one not obsolete?
