How do I iterate over a LinkedHashSet in Java?

You can iterate over a LinkedHashSet using an iterator or a for-each loop. Would you like an example?

Yes, please provide an example using both methods.

Sure! Here's how you can do it:

1. Using a for-each loop:

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

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

2. Using an iterator:

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

What are the advantages of using a LinkedHashSet?

A LinkedHashSet maintains insertion order and provides O(1) time complexity for basic operations like add, remove, and contains.
