What is the method for traversing and outputting a Tree…

In Java, you can use an Iterator or an enhanced for loop to iterate over a TreeSet and output its elements. Here are examples of both methods:

1. Iterate through and output using an Iterator.

TreeSet<Integer> treeSet = new TreeSet<>();
treeSet.add(5);
treeSet.add(2);
treeSet.add(8);
treeSet.add(1);

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

1. Traverse and output using an enhanced for loop:

TreeSet<Integer> treeSet = new TreeSet<>();
treeSet.add(5);
treeSet.add(2);
treeSet.add(8);
treeSet.add(1);

for (Integer element : treeSet) {
    System.out.println(element);
}

You can traverse and output the elements in a TreeSet using any method.
