I'm always frustrated when I don't have a quick command line parser handy -- Argh! I probably haven't looked hard enough, so here's a stupid simple command line argument parsing library for Java. For a more robust solution, take a look at commons-cli or argsparse4j. This library does NOT:

• Support required arguments
• Have a fancy help message
• Let you use multiple aliases for a single argument (like -v being the same as --verbose)
• Do most of the things the aforementioned libraries do

Just specify an argument with some dashes in front, and then the value of the argument right after, like so

java -jar Test.jar --api-key testing123 --debug --threads 16

And then grab it like

public static void main(String[] args) {
    Arghs arghs = new Arghs(args);
    
    String arg1 = arghs.getString("api-key");
    boolean debug = arghs.getBooleanOrDefault("debug", false);
    int threads = arghs.getInt("threads");

    ...
}

Hopefully this works for someone else!
