推荐答案

这取决于 List 的实现.由于您使用 int 索引数组，ArrayList 不能容纳多于 Integer.MAX_VALUE 的元素.但是，LinkedList 不受相同方式的限制，可以包含任意数量的元素.

It depends on the List implementation. Since you index arrays with ints, an ArrayList can't hold more than Integer.MAX_VALUE elements. A LinkedList isn't limited in the same way, though, and can contain any amount of elements.
