Getting ready

Every object has members—properties and methods. In case you're new to the concepts of object-oriented programming, properties are qualities of an object (what the object has), and methods are the capabilities of an object (what the object can do). Therefore, to quote (arguably) the most overused example of properties and methods: if a car is an object, its height, its color, and so on would be its properties, while accelerating, braking, and so on would be the methods that the object supports.
