How to Iterate over a Set/HashSet without an Iterator in java?

You can iterate over a Set or HashSet in Java without using an explicit Iterator by using a for-each loop. Here's how you can do it:

import java.util.HashSet; import java.util.Set; public class SetIterationExample { public static void main(String[] args) { Set<String> set = new HashSet<>(); // Add elements to the set set.add("Apple"); set.add("Banana"); set.add("Cherry"); // Iterate over the set using a for-each loop for (String element : set) { System.out.println(element); } } }

In this example:

  1. We create a HashSet called set and add elements to it.

  2. We use a for-each loop to iterate over the elements in the set. The loop iterates over each element in the set and assigns it to the variable element in each iteration.

  3. Inside the loop, we print each element to the console.

When you run this code, it will iterate over the Set and print each element:

Apple Banana Cherry

Using a for-each loop is a convenient and concise way to iterate over a Set or any other collection that implements the Iterable interface without the need for an explicit Iterator object.
