Easier Command Arguments?

So I'm working on this plugin where I'm having it so it doesn't matter what order you put it in but I was wondering, is there an easier way of doing this:

Code:java

if(args[0].equalsIgnoreCase("warn")){
    if(args[1].startsWith("u:") && args[2].startsWith("r:") && args[3].startsWith("l:")){
 
    }else if(args[1].startsWith("r:") && args[2].startsWith("l:") && args[3].startsWith("u:")){
 
    }else if(args[1].startsWith("l:") && args[2].startsWith("u:") && args[3].startsWith("r:")){
 
    }else if(args[1].startsWith("u") && args[2].startsWith("l:") && args[3].startsWith("r:")){
 
    }else if(args[1].startsWith("l:") && args[2].startsWith("r:") && args[3].startsWith("u:")){
 
    }else if(args[1].startsWith("r:") && args[2].startsWith("u:") && args[3].startsWith("l:")){
 
    }
}

 

I'd check if each one is valid, but not check every possible order...I don't understand the point of that. If they're all valid just save each one as its proper value and continue with whatever the plugin is doing.

 

For loops, switch-case blocks, and enums mix well

Code:

enum Parameter {
    USER("u", "user"),
  // ...(aliases)

    public final String[] aliases;
    Parameter (String... aliases) {
        this.aliases = aliases
    }

    public static Parameter fromString (String filter) {
        for (Parameter p : Parameter.values()) {
            for (String alias : p.aliases) {
                if (alias.equalsIgnoreCase(filter)) return p;
            }
        } return null;
    }
}

And then in your command:

Code:

for (String arg : args) {
    if (arg.contains(":") {
        switch (Parameter.fromString(arg.split(":")[0])) {
            case USER:
                // do stuff

            case ...:
               // do other stuff

            default:
               // if it matches none, do this
        }
    }
}
