Setters based on array Index in Java

I have the following:

public class  Car{
public Car()
{//some stuff
}
private Car [] carmodels  ;
public Car [] getCarModel() {
return this.carmodels;
}

public void setcarModel(Car [] carmodels ) {
this.carmodels = carmodels;

}

Now on my test class, I have something like this

public void main (String [] args)
 {
   Car car1= new Car();
   car.setcarModel(new Car[5]);//here i create an array of Car

   for(int i =0;i<5;i++)
   {
    // how can i created 5 cars and set them based on index i
    // car.setCarModel[new Car()]????
   }
 }

How can do that? I could use a temp array of type Car which I can pass to my Setter just after the loop. But is there a better way?

Solution

  • Add a setter that accepts an index:

    public void setCarModel(int index, Car carModel) {
    this.cardmodels[index] = carModel;
}

    Then, inside your loop, call

    car.setCarModel(i, new Car());
