Unhandled exception when using wrong format for -r switch

[nus-pe-bot]

Index out of bounds exception when input wrong format for -r switch. Even if the correct format is stated in the UG, it would be good to still notify users of where the issue arise from.

Steps to reproduce: add -e Career Fair -st 14:00 -sd 2023/02/10 -ed 2023/02/11 -r 3

Expected output: Incorrect date format to be raised.

Actual output:

add -e Career Fair -st 14:00 -sd 2023/02/10 -ed 2023/02/11 -r 3
