How to get element from set in java?

In Java, sets do not support indexing. To get elements:

1. Convert to a list to access by index:
   javaList<String> list = new ArrayList<>(mySet);String element = list.get(0);

1. Use an iterator:
   javaIterator<String> it = mySet.iterator();while(it.hasNext()) { System.out.println(it.next());}
