Sin There isnt difference... A list contains an attribute pointing to first elemtent and any element contain the next one... Then, you have to go to last element (which has next attribute to null) and append to it (eg. Set his next attribute) a new element... This works for any type

KrOW can't find it there. It's not a Boolean..."private StringListElement first;" "public void append(String string) " https://code.sololearn.com/c8ZKMBW2arLd/?ref=app

Sin i mean, you know how list data structure works? I understood that you have to implement yourself without use java premade types for this...
