store information and only retrieve unique information.

im supposed to retrieve org_id and store it into array list.. and then i want to make sure that only unique org_id are retrieved so that only unique org_id are displayed in the table.

however, when i tried to store the org_id inside arraylist.

ArrayList list = new ArrayList();

list.add(o.getORG_ID());

it says "unchecked or unsafe operations"

and i dont know how to compare whether the org_id is unique or not.

can anyone help me on this =)

thanks!
