Object Oriented Programming Pdf 1 lecture 8: object oriented programming (oop) oop is a way of thinking about algorithms, and a way of structuring and organizing your code. you define objects, and you give those objects variable and functions, which you then use as needed. you already do this without knowing it! for example lists are objects. Object oriented programming (oop) is a deep and complex subject, and a detailed dis cussion of it is beyond the scope of this book. however, in this chapter i will give you a solid grounding in oop to get you started. An object oriented system can be characterized as a system of cooperating objects. some objects interact only with certain other objects or perhaps only with a certain set of objects. In general, we can group the methods of a class into five categories: • modifier change the state of the object • selector accesses, but does not change the state • iterator operates across all parts of an object • constructor creates an object and initializes its state • destructor frees the state and destroys the object cleanly.

Object oriented programming © damian gordon class diagrams the classes, and their attributes and methods. it also shows the relationship between classes, with a line (association) between classes, with a verb to describe the relationship, and cardinality is indicated by numbers, in this c. Action is initiated in object oriented programming by the transmission of a message to an agent (an object) responsible for the actions. the message encodes the request for an action and is accompanied by any additional information (arguments parameters) needed to carry out the request. Do something you’ll have fun doing! use your ide and write code! create a simple game. it can be either a simple text based thing or more interactive. algorithms. don’t write everything at once, break the project into smaller, manageable tasks. some of your ideas won’t work, that’s ok! it doesn’t have to be perfect, move on. Everything in an object. a program is a set of objects telling each other what to do by sending messages. each object has its own memory (made up by other objects). every object has a type. all objects of a specific type can receive the same messages.
