java如何基于逗号拆分字符串

Question

我现在有一个字符串，它是逗号和空格的组合。为了按顺序获取特定元素，我发布了这个字符串

12:00am, 2:30am3:30am, 5:00am7:45pm,9:00pm

这是我正在尝试使用拆分字符串的字符串

List<String> interviewTimingToFrom1 = Arrays.asList(interviewTime1.split(","));

但这不起作用，我只想把12:00am，3:30am，7:45pm分为一个列表，把2:30am，5:00am，9:00am分为一个列表如何做，请有人帮忙

Answer 1

您可以使用此正则表达式：

List<String> interviewTimingToFrom1 = Arrays.asList(
                    interviewTime1.split("\\s*,\\s*|(?<=[ap]m)(?=\\d)"));

正则表达式拆分

拆分使用：

\s*,\s*          # comma surrounded by optional spaces on either sides
|                # regex alternation
(?<=[ap]m)(?=\d) # when preceding text is am or pm and following character is a digit
