Answer 1

A hash is generated for every element in a hashset. The elements are displayed based on their "hashes" but not in alphabetical order.

Answer 2

Hashes are calculated by some algorithm. It depends on that algorithm whether you get the same order as you would with alphabetical ordering.

Answer 3

they are explicitly saying if you want to keep order to use a LinkedHashSet

Answer 4

Because it's ordered by the objects hash code and not by their value.

Answer 5

as others have pointed out, hashsets are sorted after the objects hash. You can use an Arraylist and Collections.sort if you need it to be sorted in other ways.

Answer 6

so it only works on characters like A,B,C???

Answer 7

when im reading the comments from the hashset lesson in sololearn.why do they say it is in alphabetical order.so they are wrong?
