Solved Command flags

I know how a command works and how to use the arguments but how would I go along as doing something like command flags?

Example
BanManagement (/ban {user} {time} -s) "-s" means silent

I want the -s.
I'm guessing it would be to check if an argument starts with "-" then that'll be a flag. Any other suggestions?

 

Already done. Thanks though. For anyone wondering, I used this:

Code (Text):

for(String arg : args) {
    if(arg.startsWith("-s")) {

    }
}
 

fixed* pasted wrong code
