What problems did you encounter while developing your solution? How do you plan to overcome them?/How did you overcome them?

Today, I tried to create a car using java. In order to create pictures using java, it is necessary to import some methods from the library. I imported these methods during the first days of school, and, unfortunately, I did not remember how to import a library. So I tried to right click on the project and figure out what to do. My teacher, Ms. Petr, helped me on this, and now I know how to import something. Once I imported apcslib to my program, things worked out easily.
