For reading large file,

log.debug("****************Start Reading CSV File*******");
    copyFile(inputCSVFile);
    StringBuilder stringBuilder = new StringBuilder();
    String line= "";
    BufferedReader brOldFile = null;
    try {
        String inputfile = inputCSVFile;
        log.info("inputfile:" + inputfile);
        brOldFile = new BufferedReader(new FileReader(inputfile));
        while ((line = brOldFile.readLine()) != null) {
            //line  =   replaceSpecialChar(line);
            /*do your stuff here*/
            stringBuilder.append(line);
            stringBuilder.append("\n");
        }

        log.debug("****************End reading CSV File**************");
    } catch (Exception e) {
        log.error(" exception in readStaffInfoCSVFile ", e);
    }finally {
        if(null != brOldFile) {
            try {
                brOldFile.close();
            } catch (IOException e) {
            }
        }
    }
    return stringBuilder.toString();
