In the example given, we can access field value from main method (ex: inventoryCount) by calling method.inventoryCount for example cookieShop.inventoryCount then we get the value of 12.
But we cant access whole inventoryCount value because it it will give: error: non-static variable inventoryCount cannot be referenced from a static context. Why is that? Is there way to call/get the one of instance field value (ex: whole value of inventoryCount) rather than by calling each method?

Hello there, does any one know if it is possible to have more than one class in a programme and if so how you do that?
