Strings.join介绍

[英]Joins the elements of the provided Iterable into a single String containing the provided elements.

No delimiter is added before or after the list. Null objects or empty strings within the iteration are represented by empty strings.
[中]将提供的Iterable的元素连接到包含提供的元素的单个字符串中。
列表前后不添加分隔符。迭代中的空对象或空字符串由空字符串表示。
