[Solved] Arraylist for subclasses [duplicate]

Question

I’m guessing it’s the line Program.setInventorie(c1);. You need to create an instance of the Program class and call setInventorie() on that. setInventorie() is not a static method.

e.g.:

Program myProgram = new Program();
myProgram.setInventorie(c1);
