How do I replace the following array with an ArrayList.
Employee[] companyTeam = {manager, engineer1, superviso1, accountant, intern };

ArrayList cloned = new ArrayList(collection c); where c is the collection containing elements to be added to this list. Approach: Create a list to be cloned. Clone the list by passing the original list as the parameter of the copy constructor of ArrayList.
We can remove duplicate element in an array by 2 ways: using temporary array or using separate index. To remove the duplicate element from array, the array must be in sorted order. If array is not sorted, you can sort it by calling Arrays. sort(arr) method.
Duplicate items can be removed from the ArrayList by using a HashSet as duplicate items are not allowed in a HashSet. So the ArrayList is converted into a HashSet and that removes the duplicate items.
You can do something like
List<Employee> companyTeam = Arrays.asList(manager, engineer1, superviso1, accountant, intern);
