I am unsure if Collections.sort(arg1, arg2) contain an array as it's first argument? The reasom is that I know for a fact that this first arguement can be a list (List,ArraysList,etc), but when I try using a simple array, it is not accepted as a valid parameter. Is it just that Collections.sort(arg1, arg2) cannot accept a regular array? My professor gave us instructions to use a regular array but I do not think this is possible using Collections.sort(arg1, arg2). Thanks in advance!
