The primary features of an object oriented language are: * Encapsulation - This allows every object to have its own properties and behaviors separate from others, and its own little "capsule" to keep its properties in. * Inheritance - This allows an object to inherit the properties of its ancestors. * Polymorphism - The allows an object to be treated like one of its ancestors, i.e. if Truck was a subclass or descendant of an object called Automobile, it can redo behaviors that Automobile had, like Automobile has a suspension feature that has it set to 10 inches tall, Truck overwrites it and says its 30 inches tall. * Abstraction - This idea is related to encapsulation in that you don't care how the object works, but you can make it behave in certain manners.
They are three of the four pillars of object-oriented programming. The fourth is abstraction. Encapsulation describes the way in which an object is a capsule, a self-contained entity that embeds data and the methods that operate upon that data. Abstraction describes the way in which it is not necessary to know the underlying storage and implementation details of an object in order to use it. This minimises code maintenance by allowing class designers to modify their implementations without adversely affecting the consumers of those classes, provided the abstract interface remains unaltered. Inheritance describes the way in which new objects can be derived from existing objects, inheriting all the properties of the existing object and embellishing them with new properties, reducing the need to write duplicate code. Polymorphism describes the way in which derived objects exhibit correct behaviour dynamically, even when the runtime type of the object cannot be determined at compile time (which is always the case for derivatives that don't yet exist), by exploiting generic, virtual methods of the known classes (the base classes).

The four main properties of a map are scale (the ratio of distance on the map to the actual distance), orientation (the direction which the map is facing), legend (key for interpreting symbols and colors on the map), and title (the description or name of the map).
