数组在java中使用“，”而不是“，”拆分字符串

Question

我有这样一个字符串：

123,TV,August 14, 2020,"This is a fantasy series, and top rated"

我用的是字符串。但我的分隔符应仅基于逗号分隔字符串，不带尾随空格

预期产量

["123","TV","August 14, 2020","This is a fantasy series, and top rated"]

实际产量

["123","TV","August 14"," 2020","This is a fantasy series", " and top rated"]

考虑到所有逗号，它正在拆分字符串。我只想考虑没有尾随空间或双引号（“”）的逗号。

有人能给我一些建议吗

Answer 1

您可以与Negative Lookahead(?!\s)组合以断言逗号后没有空格

String s = "123,TV,August 14, 2020 ,\"This is a fantasy series, and top rated\"";
List<String> parts = Arrays.stream(s.split(",(?!\\s)"))
        .map(x -> x.replaceAll("^[\"\\s]|[\"\\s]$", ""))
        .collect(Collectors.toList());
for (String p : parts) {
    System.out.println(">>" + p + "<<");
}

>>123<<
>>TV<<
>>August 14, 2020<<
>>This is a fantasy series, and top rated<<
