Here is the "Object Oriented Programming Theory" exercise from the Junior Programmer Pathway. You can see 4 types of cubes. The base one (white) which has a color and can move. The other 3 cubes, inherit from it, and have the same base properties, but their move action has a variation. The red one can sprint, the yellow one can slow down, and the blue one can "mimic" the other two at random. Enjoy!

Here is the "OOP Theory" exercise from the Junior Programmer Pathway. You can see 4 types of cubes. The base one (white) and the other 3 that inherit from it and expand its behavior. Enjoy!
