I'd like to say i'm not expert about java, i'm just joking with a Scholastic exercise. so let's explain. i want make a table where i can display my car, my bike, and both together. for now i've only a car class so i'm working with it. i'm stuck in a problem with a listener so let's paste my code and the error first, my tablemodel.

so i just want make this. when i change the value on the spinner, i want add or delete rows on my table, when i press the JButton, and i'll do this with an edit on my list. so why i get this error? and why when i edit Frame Tabella, i get the following 2 error, while i compile, on the AutomobileTableModel? error:
.\AutomobileTableModel.java:48: error: cannot find symbol
automobili.removeRange(automobili.size(), rowIndex);
^
symbol: method removeRange(int,int)
location: variable automobili of type List<Automobili>
.\AutomobileTableModel.java:54: error: cannot find symbol
fireTableRowsInsert(automobili.size(), rowIndex);
^
symbol: method fireTableRowsInsert(int,int)
location: class AutomobileTableModel
2 errors
to solve this i just delete and write again a letter i've deleted, than i recompile and it work. why i get this error too?
