读取由定界符分隔的texfile的内容

Question

“约翰”，“ 100.00”，“ 200.00”

如何读取文本文件的内容，然后在引号下打印字符串。

输出应为Jhon 100.00 200.00

String CUSTOMER, CURRENT, NEW;

    Scanner sc = new Scanner(str);

    sc.useDelimiter(",");

    while(sc.hasNext()){

        CUSTOMER = sc.next();

        CURRENT = sc.next();

        NEW = sc.next();

           System.out.println("" + CUSTOMER + " " + CURRENT + 

             " " + NEW);  

          }

          sc.close();

如何将标记与引号分开。我得到的上述代码的输出是“ Jhon”“ 100.00”“ 200.00”

您可以通过以下命令获得所需的输出：public static void main(String[] args) {    Pattern p = Pattern.compile(".*?\\\"(.*?)\\\".*?");    Matcher m = p.matcher("\"John\",\"100.00\",\"200.00\"");    while (m.find()) {        System.out.println(m.group(1));    }}解释.*?   - anything\\\" - quote (escaped)(.*?) - anything (captured)\\\" - another quote.*?  - anything输出John100.00200.00
