What protected Really Means

Dessert

protected int calories;

Cake

Pudding

WhippedCreamCake

Each class that extends Dessert inherits calories.

Code in the Cake class can access calories only through a reference to a type that is a Cake or a subclass of Cake.

Code in the Cake class cannot access the calories field of a Scone or a Pudding or a generic Dessert.

Scone

Note: protected static fields can be accessed in

any extended class.
