Need help defining the getPrice method in this subclass :   //I am trying to determine how I should define the getPrice method. The shirts can range from Small to XXXL and the price varies. The price is determined by the size: $22.99 for XXL or XXXL, and $19.99 for all other sizes. There are two other classes that I have complied. But the method I need help with only goes with this code. Let me know if you need more info. Help please! 

    

 

    public class TeeShirt
        {
           private int orderNumber;
           private String size;
           private String color;
           private double price;
           public void setOrderNumber(int num)
           {
            orderNumber = num;
           }
           public void setSize(String sz)
           {
             size = sz;
           }
           public void setColor(String color)
           {
               this.color = color;
           }
           public int getOrderNumber()
           {
              return orderNumber;
           }
           public String getSize()
           {
              return size;
           }
           public String getColor()
           {
               return color;
           }
           public double getPrice()
           {
               return price;
           }
        }//end
