Need help with boolean and not adding a vehicle with the same identification

Question

public boolean hasVehicleIdentificationNumber(String vehicleNumber)

Hello, im having a hard time with returning true "Return true if the car lot has a vehicle with the number provided in the inventory" and then return false if not, but i think there is something wrong with my code and i cant seem to figure it out.

public void addVehicle(Vehicle theVehicle)

How do i not add a vehicle with the same identification? I tried an if statement and foreach but i really dont know what i was doing.

I think your main issue is your confusion between Java and JavaScript. They are completely different despite their names.

You need to put your code into the Java interpreter on here and try again.
