You could create a variable to count how many raw oyster specials you have then loop through your list and increment it for each raw oyster special

you'd have to count them up, i suppose
probably with a map, so like A, B, A gets reduced to A x2, B correctly
or you could store them in a map to begin with, to track their counts directly, rather than using a list

Yeah thats probably a better approach
But it might require some minor refactoring

is there a website that shows example?

there's an section on the collections api there, with an article on maps

<string, integer>

does it have to be capitalized?
ArrayList<String> orderL = new ArrayList<String, int>();
median mural
it needs to be Integer, primitives cannot be used as generics
shy estuary
ok
median mural
but yes, capitalized, because they're reference types
nova arch
Integer is the wrapper class for int
shy estuary
ArrayList<String> orderL = new ArrayList<String, Integer>();
or would i need to add integer on the front one as well
median mural
lists and maps are completely different structures
shy estuary
ok so keep it as it is
median mural
no
shy estuary
ArrayList<String, Integer> orderL = new ArrayList<String, Integer>();
median mural
List<E> list = new ArrayList<>(); or whatever for lists, but that obviously doesn't work to create maps
lists are not maps
read the guide please
Map<K, V> map = new HashMap<>();
with the proper K and V
shy estuary
but i used ArrayList<String> orderL = new ArrayList<String>(); and worked
nova arch
Map != list
