When the RB crew that drops off your container with your house and parts leaves, you are not left alone to assemble your dream home. RB Construction Co. has also left a little assistant, Bob the robot. Bob is here to keep your house building project organized. This is a very good thing because it is easy to misplace things or try and assemble your home in a wrong manner. He will help you with what you would like your project to look and perform like.
Programmers work with classes.
To be proper, an object is instantiated by its class. For example, your house needs a front door. Luckily RB Construction has created the Door Class to be added to the house. Because the good people at RB Construction built it to do act, look and respond as you would expect a door to do. You drag the Door Class out from the container and place it on your smart house.
