| Example Customer[] Cust = new Customer[10]; <- i find that if i pre initialize the arraysize to be 30, and if only the first 2( 0 and 1) has contents, when the comparator trys to get Name = ((Customer) anotherCustomer).getname().toUpperCase(); of the "null" array, error will occur. is there anyway for the comparator to know that the next is empty array and end the compare operation to return back? thanks! | ||
