哈希映射键比较

Question

I am making a hashmap by reading a particular section in the input file. However the input files do not have a standard indentation format, ie, some of the lines start with a # characters , while some do not. I am supposed to capture the key and value from the file. Here is my code:

String schedule = "config [\"Sql\"] = \\";
        Scanner scanner = new Scanner(f1);
        while (scanner.hasNext()) {

            sCurrentLine = scanner.nextLine();

            if (sCurrentLine.contains(schedule)) {
                System.out.println(f1.getFileName()+" Contains a schedule");    
                scheduleFlag = true;
            }
            else if(sCurrentLine.contains("config [")) {
                scheduleFlag = false;
            }
            if(sCurrentLine.trim().startsWith("(")  && sCurrentLine.trim().endsWith(",") && scheduleFlag == true) {
                scheduleName = sCurrentLine;
                scheduleName = scheduleName.substring(scheduleName.indexOf('"')+1, scheduleName.lastIndexOf('"'));
                //writer.write(scheduleName);
                out.write(scheduleName.getBytes());
                HashMapping = true;

            }
            if(scheduleFlag == true && HashMapping == true) {
                String [] values = sCurrentLine.split(":");

                if (values.length < 2);
                else {
                hm.put(values[0], values[1]);
                }
            }

Here is a section of input file :

#config ["Sql"] = \
#[
#   ("KB",
#       {
#           "subsystem":              "DMN",
#           "enabled":                "0",
#           "freqtype":               "4",
     }

I just want the string including the double quotes in my key, ignoring the # character(which may or may not be present in a given file). Is there any way?

Search for matches of a regular expression like

"[^"]*"

You can iterate over the elements in quotation marks by something like:

Pattern p = Pattern.compile("\"[^\"]*\"");
Matcher matcher = p.matcher(yourInputString);

while (matcher.find())
  {
      //do something with the match

  }
