well not to sound like a smartass, but your code is not so good for
copying arrays. use System.arrayCopy() or clone() instead.
String[] vector= new String[4];
System.arrayCopy(list,0, vector, 0, blah.vector);
or
String[] vector = (String[]) list.clone();
also, using names "list" or "vector" is not appropriate for array variables.
