at the moment, I'm exercising with linked list but I have a problem with a code. The code below runs and work, but when I'm trying to add some nodes using a for generating random numbers it gave me this error. Before adding the for the code works and run adding the now as you can see into main. Maybe I missed something. Can someone help me to understand?
P.S. The commented part was the part of the main that I tryed to "upgrade".

Why did you declarepazzas adouble, when you assign it anintvalue, and want to pass it to a method expectingint? Change declaration toint.

double pazz = rand.nextInt(50) + 1;
Here you set pazz as double. You should set it to int instead.
