Arrays?

[inland swallow]

Why do I get an error in my array:

    public static void main(String[] args) {
        // Create an array of 4 vehicles
        Vehicle[] myVehicles = new Vehicle[4];

        // Populate each entry of the array with a vehicle
        myVehicles[0] = new Vehicle("Honda", 4, 6f, true);
        myVehicles[1] = new Vehicle("Bicycle", 2, 0f, true);
        myVehicles[2] = new Vehicle("Motorcycle", 3, 2f, false);
        myVehicles[3] = new Vehicle("Toyota", 4, 4f, false);
        // 3 because it starts at 0, so only need 0,1,2,3```
```public class Vehicle {
    // Instance variables
    private String Type; // type of vehicle
    private int Number_of_Wheels; // number of wheels
    private float Engine_Size; // the size of the engine
    private boolean Gas_Electric; // USE BOOLEAN
}```

what's the error ? Do you have a constructor matching your passed in arguments in your vehicle class ?

[inland swallow]

'Vehicle()' cannot be applied to '(java.lang.String, int, float, boolean)'

our teacher said we didnt need a constructor

[half ember]

then he probably said to use getters and setters

otherwise there is no way to set the values of the fields in your vehicle class

[inland swallow]

        return Type;
    }
    public int getNumber_of_Wheels() {
        return Number_of_Wheels;
    }
    public float getEngine_Size() {

        return Engine_Size;
    }
    public boolean getGas_Electric() {
        return Gas_Electric;
    }
    public void setType(String newType) {
        Type = newType;
    }
    public void setNumber_of_Wheels(int newNumber_of_wheels) {
        Number_of_Wheels = newNumber_of_wheels;
    }
    public void setEngine_Size(float newEngine_Size) {
        Engine_Size = newEngine_Size;
    }
    public void setGas_Electric(boolean newGas_Electric) {
        Gas_Electric = newGas_Electric;
    }```

it's a little clunky but you will have to create a new vehicle without any arguments new Vehicle() and then set the values of the fields manually using your getters.

[ember vapor]

like this ```java
myVehicles[0] = new Vehicle();
myVehicles[0].setXXX()

[inland swallow]

would my way work with a constructor?

[half ember]

yes it would

[pearl light]

Also note that the record types enable to just give the list of fields without having to define a constructor that sets them. Much more straightforward

[inland swallow]

yea idk what that means but okay!
