How do you parse arguments for a java program?

Question

I\'m making a Selenium WebDriver java program. I have 25 application and 4 environments. I need to be able to pass something like -app app1 app2 app3 ... appn -env env1 env2 env

I don't think recursion is needed. You can do something like this:

public static void main (String[] args)
{
    List apps = new LinkedList<>();
    List envs = new LinkedList<>();
    List current = null;
    // parse arguments
    for (String arg : args)
    {
        if (arg.equals("-app")) current = apps;
        else if (arg.equals("-env")) current = envs;
        else if (current != null) // add argument
            current.add(arg);
    }
    // parsing finished
    Application.doSomethingWith(apps, envs);
}
