Question

这个问题已经有答案了:

Java - Append quotes to strings in an array and join strings in an array (7 个回答)

已关闭 5 年前。

例如，我有字符串数组:

String[] arr = {"one", "two", "three"};

可以使用 Guava Joiner 获取这样的字符串:

"<one>, <two>, <three>"

哪里,是分隔符和 < >是每个元素的前缀和后缀。谢谢。

您还可以使用 Collectors.joining() ，如下所示:

    String[] arr = {"one", "two", "three"};        
    String joined = Stream.of(arr).collect(Collectors.joining(">, <", "<", ">"));
    System.out.println(joined);
