LinkedIn principal author Doug Winnie explains how everything in object-oriented programming is based on the concept of an object. An object can have a number of different characteristics. It can perform certain actions, and can have a name to identify it. These three elements comprise the basics of object-oriented programming or OOP.
- Object-Oriented programming is a core foundation…of most coding and programming languages.…To say something is object-oriented, or OO,…means that everything, and I mean everything,…is considered an object.…But what is an object.…I could pick up a pair of scissors…and say that it is an object.…But does that apply to programming.…It actually does, and let me explain how.…Think of a typical pair of scissors.…Scissors can have different colors,…lengths, or grips on the handles.…
Some scissors are designed for right-handed people,…some for either, and some are for lefties.…These are all characteristics of various types of scissors.…Scissors can basically do one or two things.…You can squeeze them together to cut,…adjusting how much you want to cut…based on the distance you squeeze.…You can also open them up, and use them…to open a box or a wrapper of some sort.…These are actions that a scissor can do.…At your house or office, you might have…lots of different scissors.…
First, you know them all as scissors.…But you might have one in the junk drawer,…

11/28/2016Join Doug Winnie as he explains the principles of programming and helps you connect to core concepts by exploring three ways that programmers perform their jobs. Doug starts by sharing the history of coding and then dives into functions, values, variables, and parameters used to define actions. He covers capturing input from users, creating conditional tests, using loops with arrays, and object-oriented programming basics. He also takes you beyond programming, into processes like debugging, refactoring, and building iteratively.
