Error while parsing the command line: Unrecognized option: -f

public void run(String... args){
     Options options = new Options();
        options.addOption("h", "help", false, "prints the help content");

        LoadReferenceFileRequest request=new LoadReferenceFileRequest();
       try{
          CommandLineParser parser = new DefaultParser();
          CommandLine commandLine = parser.parse(options, args);
          if(commandLine.hasOption("f") && commandLine.hasOption("u") && commandLine.hasOption("d")) {
              String fileType = commandLine.getOptionValue("f");
