code: public static JSONArray copy(final JSONArray src) {
          final JSONArray dest = new JSONArray();
          final int len = src.length();
          for (int i = 0; i < len; ++i) {

  Equivalent to calling {@link #copy(JSONArray, boolean) copy(src, true)}.
  
  @param src {@code JSONArray} to copy
  @return A new {@code JSONArray} copied from {@code src}
