ListButton - Is it the correct way?

[Dr. Stefano Sancese]

Hi to all,




I wrote this class:

class lbtCustomer {
            private String id;
            private String name;
            private String address;

            lbtCustomer(String c1, String c2, String c3) {
                id = c1;
                name = c2;
                address = c3;
            }

            public String getKey() {
                return id;
            }

            @Override
            public String toString() {
               return name + " - " + address;
            }
        }

and I populated the ArrayList of the ListButton with:

ArrayList lbtValues = new ArrayList();

    lbtCustomer r1 = new lbtCustomer("1","John Doe","New York");;
    lbtCustomer r2 = new lbtCustomer("8","Charlie Brown","Los Angeles");
    lbtCustomer r3 = new lbtCustomer("2","Donald Duck","Orlando");
    lbtCustomer r4 = new lbtCustomer("9","Snoopy","Los Angeles");

    lbtValues.add(r1);
    lbtValues.add(r2);
    lbtValues.add(r3);
    lbtValues.add(r4);

    listButtonTest.setListData(lbtValues);



The test case works, but I wonder if there is a better way.






Ciao

Stefano

in a form, I have a ListButton that I need to populate with 1000 customers data (Id, Name, Address). With the toString method I can format the information showed to the user and with the getKey method I can retrieve the Id of the chosen record. I'm concerned about the cost (CPU and memory) associated with the instantiation of the 1000 objects that I need for the real case. Perhaps two array lists: one with the data to show to the user and the other to store the id of the corresponding Customer? P.s. I'm realy green to java and - YES - I'm Reading the F...... Manuals. There are simply too many of them ;-)
