In Java, a Set collection can be traversed using an iterator or the enhanced for loop.

The steps to iterate through a Set collection using an iterator are as follows:

Set<String> set = new HashSet<>();
set.add("A");
set.add("B");
set.add("C");

Iterator<String> iterator = set.iterator();
while(iterator.hasNext()){
    String element = iterator.next();
    System.out.println(element);
}

The steps for traversing a Set collection using an enhanced for loop are as follows:

Set<String> set = new HashSet<>();
set.add("A");
set.add("B");
set.add("C");

for(String element : set){
    System.out.println(element);
}

You can iterate through the elements in a Set collection and perform operations regardless of the method used.
