The following example uses a QualifiedSwitch to allow the user to specify the language(s) to use in verbose mode.

    public static void main(String[] args) throws Exception {
        JSAP jsap = new JSAP();
        
        FlaggedOption opt1 = new FlaggedOption("count")
                                .setStringParser(new IntegerStringParser())
                                .setDefault("1") 
                                .setRequired(true) 
                                .setShortFlag('n') 
                                .setLongFlag(JSAP.NO_LONGFLAG);

        opt1.setHelp("The number of times to say hello (default=1).");
        jsap.registerParameter(opt1);
        
        QualifiedSwitch sw1 = (QualifiedSwitch)
                                (new QualifiedSwitch("verbose")
                                .setShortFlag('v')
                                .setLongFlag("verbose")
                                .setList(true)
                                .setListSeparator(','));
        
        sw1.setHelp("Requests verbose output.");
        jsap.registerParameter(sw1);
        
        UnflaggedOption opt2 = new UnflaggedOption("name")
                                .setStringParser(new StringStringParser())
                                .setDefault("World")

        jsap.registerParameter(opt2);

        if (!config.success()) {
            
            System.err.println();

            // print out specific error messages describing the problems
            // with the command line, THEN print usage, THEN print full
            // help.  This is called "beating the user with a clue stick."
            for (java.util.Iterator errs = config.getErrorMessageIterator();
                    errs.hasNext();) {

            System.err.println(jsap.getHelp());
            System.exit(1);
        }
        
        String[] names = config.getStringArray("name");
        String[] languages = config.getStringArray("verbose");
        if (languages.length == 0) languages = new String[] {"en"};
