It defines how the cookie will look.…But the cutter itself is not a cookie.…And we only need this one cutter to create…a tray full of round cookies,…each a separate object ready for the oven.…- Remember that the class always comes first.…You can't make round cookies without the circular cutter.…Now, there are three components that make up a class…in object-oriented programming.…Each class has a name,…literally what is it?…For example, a round cookie.…

A class can have attributes to describe that object,…
