Java String.split多个字符分隔符

Question

I would like to parse just one long line from file based on " and , and [ and ] and { and }

For eg

{"ColumnTypes":"int32","fstring32","int32"],"ColumnNames":"ProductId",","ProductName","Quantity"]}

I actually need two different array from this line column types and column names. I tried string.split("\\\\W") but it is not working.

Please guide. Thanks in advance.

Answer 1

你需要拆分多个 \\\\W字符（添加一个+ ），但首先从前面剪掉这些字符，这样你就不会得到一个空白的第一个元素：

String[] array = string.replaceAll("^\\W+", "").split("\\W+");

Answer 2

最简单的方法（使用正则表达式）将允许多个非单词字符匹配：

string.split("\\W+")
