OOP

• a method for organizing modular programs

• each object has its own local state

Objects

• combine data values with behavior

• represent information and behave as the things they represent

• Instances can be constructed by calling the class on arguments that characterize the instance

Class

• a term for its instances

• every object is an instance of some particular class

• class definition - specifies the attributes and methods shared among objects of that class

Interface

• describe how you can interact with an object without necessarily implementing it
