java collection转换为list

public ArrayList(collection<?> extends E> c) {
 elementData = C. toArray();
  size = elementData. length;
  // c.toArray might (incorrectly) not return Object[] (see 6260652)
  if (elementData. getClass() != Object[]. class)
  elementData = Arrays . copyOf(elementData, size, object[].class);
}
