Issue with object arrays and their usage among frames

I need to find a way to handle the object array to send it to the other frame “Start” I’ve tried various ways but I can’t, I’m just a beginner in the field of OOP, I’ve tried creating methods but still I haven’t been able to solve the program. I use Eclipse

I’ve tried inserting methods and initializing the object on different sides, but I need a method
