QuestionNeed help figuring out why I got a java.lang.NullPointerException. Pin

MemberEmmanuel Guerrero9-Jun-21 10:03 
I understand that a NPE can come from a variable or method returning null. But what I'm trying to do is get a bank account balance. To do this I first have to correctly enter the account id and nip, which I can do without problems. Then I have 4 options to pick from (right now I only have one implemented properly) so I pick Consulta (consult) and what I should be getting is the account balance but I get a NPE error. Can someone help me figure this out? The classes involve during this process should be SolicitudSaldo (consult balance), ATM, Cuenta (Account), BaseDatosBanco (Bank data base) and Transaccion (Transaction). I think the problem might have to do with how I declare ATM in my Jframe INTERFAZ_TRANSACCIONES.

I'll paste a link to my code since It's quite a lot and I don't want to make this post any longer. My project is in the master branch.

Heres a link to my project in gitHub
