Hi @parichko,

Please read the [guidelines](https://discourse.processing.org/faq#homework) for asking about homework 😉

Programming is first describing your needs then answering those problems with code so in your case try to ask yourself the following questions:

- How to make a circle shape?
- How to make that circle move?
- How to change the shape of a circle when an event is triggered?
- How do I detect the intersection of a circle an a wall?
- How do I modify the trajectory of the circle so that when it touches a wall it bounces?

Gradually solving those questions will lead you to the final program and this is the process of software engineering! 😋
