/**
 * Returns the element or elements that match the specified key. If it is the name

 * the array, that element is returned. Finally, if it is the name of an element or
 * elements in the array, then all those elements are returned. Otherwise,
 * {@link #NOT_FOUND} is returned.// www  .  java  2 s  .com
