General fix: only read args[i + 1] when it exists. For options that require a value, guard with i + 1 < args.length; if missing, fail fast with a clear exception.

Best fix in this file: in parse_args (lines ~36–106), add a single guard at the top of the loop to validate value-bearing flags before any branch accesses args[i + 1]. This avoids repetitive checks and preserves existing behavior for valid inputs. Then keep the existing assignments/parsing logic unchanged.

Concretely:

• File: java_package/brainflow/src/main/java/brainflow/examples/BrainFlowGetData.java
• Region: inside parse_args, immediately inside the for loop and before first if (args[i].equals(...)).
• Add:
  • String arg = args[i];
  • a combined condition checking whether arg is one of the value-requiring flags and i + 1 >= args.length
  • throw IllegalArgumentException with a helpful message.
• Optionally use arg in existing if statements for readability (no functional change).
