Problem
Create Beverage class. Provide instance fields for name, sizeInOunces, and calories (for example, "Whole Milk", 8, 145). Each of these should be accessible only within the Beverage class. Create constructor, which initializes the instance fields Write toString() method, modeled after the standard Java toString() method, to return a String representation of the Beverage. Write equals() method, modeled after the standard Java equals() method. Two Beverages are equal if they have the same name and sizeInOunces.
