docs: <p>Gets the hash code for multiple objects.</p>
  
  <p>This allows a hash code to be rapidly calculated for a number of objects.
  The hash code for a single object is the <em>not</em> same as {@link #hashCode(Object)}.
  The hash code for multiple objects is the same as that calculated by an
  {@code ArrayList} containing the specified objects.</p>
  
  <pre>
  ObjectUtils.hashCodeMulti()                 = 1
  ObjectUtils.hashCodeMulti((Object[]) null)  = 1
  ObjectUtils.hashCodeMulti(a)                = 31 + a.hashCode()
  ObjectUtils.hashCodeMulti(a,b)              = (31 + a.hashCode()) * 31 + b.hashCode()
  ObjectUtils.hashCodeMulti(a,b,c)            = ((31 + a.hashCode()) * 31 + b.hashCode()) * 31 + c.hashCode()

  @param objects  the objects to obtain the hash code of, may be {@code null}
  @return the hash code of the objects, or zero if null

  @deprecated this method has been replaced by {@code java.util.Objects.hash(Object...)} in Java 7 and will be
  removed in future releases.
