在逗号上分割字符串，但括号内不分割逗号

Question

Now I have a task about Java IO , I need to read file line by line and save this data into database, But Now I got a problem.

"desk","12","15"，"(small,median,large)"

I want to use string.split(",") to split by , and save data into each column. But I found that the data in the () has also been split, I do not want to split (small, median, large) and I want to keep this integrity. How can I do that? I know I can use regualr expression , but I really do not know how to do it?

Answer 1

或者，如果Java必须是：)，则可以用“ \\\\ s * \\” \\\\ s *，\\\\ s * \\“”分割，然后在第一个字段的开头和结尾处添加“第二个。我输入\\ s是因为我看到您也有空格分隔符-15“，blank”（小

Answer 2

You could solve this by using Pattern and Matcher . Any solution using split would just seem like a nasty workaround. Here's an example:

public static void main(String[] args){
    String s = "\"desk\",\"12\",\"15\",\"(small,median,large)\"";
    Pattern p = Pattern.compile("\".+?\"");
    Matcher m = p.matcher(s);
    List<String> matches = new ArrayList<String>();

    while (m.find()){
        matches.add(m.group());
    }

    System.out.println(matches);
}

Answer 3

(\(.+?\)|\w+)

the code above matches the result below this will allow for a more flexible solution that some of the other posted ones. The syntax for the regular expression is in another answer on this page just use this regular expression instead

desk
12
15
(small,median,large)
