Getting the following err when compiling " Elevator.java uses or overrides a deprecated API"

Question

I keep getting the following error when compiling the following code and can't find the source "Elevator.java uses or overrides a deprecated API" "Note: Recompile with -Xlint:deprecation for details". I believe it is because I am using an outdated input but can't for the life of me find where. Im sure it is obvious. Can anyone nudge me in the correct direction? Thank you in advance
