title: Does .equals on Hashset return true regardless of order?
body: <p>For the Hashset in java there is a .equals method comparing elements in each set.
  Will this return true regardless of order?</p>
  
  <p>Example, let's say we have one set with elements {a,b,c} and another with elements {b,c,a}</p>
  
  <p>if you use .equals on these two sets will it return true, or does it have to be sorted?</p>
