推荐答案

来自文档:

列表:元素的一般有序集合.该接口中的方法仅支持对列表的只读访问；请参见图11.通过MutableList接口支持读/写访问.

List: A generic ordered collection of elements. Methods in this interface support only read-only access to the list; read/write access is supported through the MutableList interface.

MutableList :元素的通用有序集合，支持添加和删除元素.

MutableList: A generic ordered collection of elements that supports adding and removing elements.

您可以修改MutableList:更改，删除，添加...其元素.在列表中，您只能阅读它们.

You can modify a MutableList: change, remove, add... its elements. In a List you can only read them.
