Meaning – In programming, the word class refers to one of the building blocks of objects oriented programming. The large number of circuits inside computers allow them to route data to different locations and perform complex calculations.
Inside a class, there are two components – methods and fields (or properties). Methods can store the code for doing actions; in this example you could have a drive method and a brake method, and maybe a turnRight and turnLeft method. Fields store data; you could have a color field, a speed field and a size field.
Example of usage – “As a programmer, the first thing he did inside his program, was to create classes. They formed the blueprint for the rest of his code.”
