Question

I’m very new with java and can’t figure this out!
this is how it should look like , but it gives me an error and i’m not sure if i have to convert it or not !
or i’m doing something else wrong!!!

here is my requirements:
Assign values to variables using the provided vehicle data. Refer to the Data File Layout Information for information of accessing these vehicle data values.
1. speeds

public class Bicycle extends Vehicle implements IOutput {

private static int speeds;

public Bicycle(String[] vehicleData) {
    super(vehicleData,speeds);   // get error: The constructor Vehicle(String[], int) is undefined

            // or i should this one :
    speeds = Convert.toInteger(vehicleData[0]);
}

here is the vehicle class

public Vehicle(String[] vehicleData) {
    count++;
    owner= new Owner(vehicleData);

    setVehicleType(Convert.toInteger(vehicleData[0]));
    make = vehicleData[1];
    model = vehicleData[2];
    color = vehicleData[3];
    purchaseDate = vehicleData[4];
    cost = Convert.toDouble(vehicleData[5]);
}

Answer 1

super is calling the Vehicle constructor, which accepts only a String, not a String and a int.

Change to this.

// remove static
int speed;
public Bicycle(String[] vehicleData) {
    super(vehicleData);
    speeds = Integer.valueOf(vehicleData[0]);
}
