How to fill wrapper class attributes

I want to to fill this class  but I can't reach wrapper attributes:
  
public class PricingMotor_cls {
	public Double cost;
	public OrderItems[] orderItems;

//Wrapper for OrderItem
	public class OrderItems {

		public Integer quantity;
		public CashAmounts creditAmounts;
	}

	//Wrapper CashAmounts 
	public class CashAmounts {
		public Double totalPrice;
		public OrderConditions[] orderConditions;
	}
        //Wrapper OrderConditions 
        public class OrderConditions {
		public String conditionType;
		public Decimal amount;
	}

}

I try  
List<ISSM_DeserializePricingMotor_cls.OrderItems> abc = new ISSM_DeserializePricingMotor_cls.OrderItems[1];
abc[0].quantity = 1;

but told me:  FATAL_ERROR System.ListException: List index out of bounds

what I'm doing wrong...
how I fill all object?

Hi Hector,

To accomplish what you want, you have to create a new instance of PricingMotor_cls and then create a new instance of List<OrderItems>. Try this code below:
  
PricingMotor_cls  pm = new PricingMotor_cls ();
pm.orderItems = new List<OrderItems>();
OrderItems item1 = new OrderItems();
item1.quantity = 1;
pm.orderItems.add( item1 );

I hope you find this solution helpful. If it does, please mark as Best Answer to help other too.

Regards.
