java在创建带有数组的实例时遇到问题

Question

我无法利用实例数据创建基于插槽索引的相应阵列。在这种情况下，“太阳能”或“气候”将决定创建哪个阵列。 我只需要main和createWarehouses方法的帮助。 任何帮助都将不胜感激

import javax.swing.JOptionPane;

public class WarehouseTest
{



    public static void main(String args[])
    {
        SolarWarehouse sw1 = new SolarWarehouse ( "2200", "10", "5", "5", "First Street", "Dallas", "Texas", "76000", "Solar", "25");

        ClimateControlledWarehouse ccw1  = new ClimateControlled Warehouse ( "5550", "12.75", "2", "3", "Mitchell Drive", "Arlington", "Texas", "76019", "Climate", "80.5");
        ClimateControlledWarehouse ccw2  = new ClimateControlled Warehouse ("12000", "17.50", "6", "7", "Jones Blvd", "Burleson", "Texas", "76120", "Climate", "77.3");
        SolarWarehouse sw2 = new SolarWarehouse ("7235", "22.35", "54", "80", "Smith Circle", "Keller", "Texas", "75020", "Solar", "6");


        Warehouse wArray[] = new Warehouse[4];

        wArray[0] = sw1;
        wArray[1] = ccw1;
        wArray[2] = ccw2;
        wArray[3] = sw2;

        wArray = createWarehouses(dataArray);



        JOptionPane.showMessageDialog(null, purchaseItems(wArray));
        JOptionPane.showMessageDialog(null, printWarehouses(wArray));
        JOptionPane.showMessageDialog(null, printWarehouseCharge(wArray));
