Question

I am trying to write this method - checkValidBusType() : returns true if entered bus type is valid and exists in BusType enum and can be converted to a BusType object

Here is the list of Stations

// List of Bus Stations
public enum BusStation {
    PHX,
    LAX,
    LVS,
    SAN,
    SFO,
    YUM;

public static String getBusStationCity(BusStation busStation) {

        switch (busStation) {
        case PHX:
            return "Phoenix";

        case LAX:
            return "Los Angeles";

        case LVS:
            return "Las Vegas";

        case SAN:
            return "San Diego";

case SFO:
return "San Fransisco";

default:
return "Unknown City";

}
}

}

Here is the start of my method

private boolean checkValidBusType() {

return false;
}

This was my initial attempt:

private boolean checkValidBusType(String busStation) {
        boolean validBusType = false;
        BusStation[] busStationName = BusStation.values();
        for(BusStation busStationNames : busStationName)
        {
            if((sourceStationText.getText() == busStation) && (destStationText.getText() == busStation))
        {
            validBusType = true;
        }
            else
            {
                validBusType = false;
            }
        }
        return validBusType;
    }

Explanation / Answer

Hi,

I have provided the class with functions required to validate bus type based on given enum values.

public class Station {
   public enum BusStation {
       PHX, LAX, LVS, SAN, SFO, YUM;
   }

   public static String getBusStationCity(BusStation busStation) {
       switch (busStation) {
       case PHX:
           return "Phoenix";

       case LAX:
           return "Los Angeles";
       case LVS:
           return "Las Vegas";

       case SAN:
           return "San Diego";
       case SFO:
           return "San Fransisco";
       default:
           return "Unknown City";
       }
   }

   public static boolean checkValidBusType(String busStation) {
       boolean validBusType = false;
       for (BusStation givenStation : BusStation.values()) {
           if (givenStation.toString().equals(busStation)) {
               validBusType = true;
           }
       }
       return validBusType;
   }
   public static void main(String[] args) {
       String checkBus="SFO";
       //check if bus type is value by passing a string value
       System.out.println(checkValidBusType(checkBus));
       //Get the name of the city using bus station
       System.out.println(getBusStationCity(BusStation.valueOf(checkBus)));

   }
}
