Thread: Return a List from a method

Hello!

I have created a list of customer in a class called bank like this:

 private List<customer> customerList = new LinkedList<>();
 
    public List getCustomerList()
    {
        return customerList;
    }

Then I´ve added customers to that list via another test class. Now I want to print out the customer list via a for-loop in that class:

for (Customer c : bank.getCustomerList())
            {
                code for print out
            }

I then get an error message saying: "Incompatible datatypes, Required Customer, Found: Object"

Why is that? I know that I can just declare the list as public and then call the variable directly, but I wanna know why the other version doesn't work.

Thanks!

Thank you! That worked
