There was a problem hiding this comment.
The new guard only checks that i + 1 exists, so a missing value in the middle of the CLI can still consume the next flag as data (for example, --ip-address --board-id 1 sets ip_address to --board-id and then skips parsing --board-id because of the later i++). This silently misconfigures inputs instead of reporting a missing value, which is a regression from the intended validation behavior. Consider treating a known flag token in args[i + 1] as an absent value and throwing IllegalArgumentException in that case as well.

To fix this safely without changing intended behavior, validate that an option requiring a value actually has a following token before reading
args[i + 1]. The best approach here is to add a guard at the top of the loop: whenargs[i]is one of the known value-taking flags andi + 1 >= args.length, throw anIllegalArgumentExceptionwith a clear message. Then, after consuming a value, incrementi(i++) so the value token is not reprocessed as another flag.In
java_package/brainflow/src/main/java/brainflow/examples/Markers.java, updateparse_argsloop body (lines 31–69 region) to:args[i]into a localarg.argis a known flag requiring a value and whether a value exists.argin comparisons and reads fromargs[i + 1].i++;inside each matched branch after assignment/parsing.No new imports or dependencies are needed.
