Getting an element from a Set

A Set is a collection of elements in which each element can only occur once. A Set does not have a specific order and does not provide a way to access its elements by their position.

To get an element from a Set, you can use the contains method to check if the element is in the Set, and then use the iterator method to iterate through the elements of the Set and find the element you are looking for. Here's an example of how you can do this:

import java.util.Set;
import java.util.HashSet;
import java.util.Iterator;

public class Main {
    public static void main(String[] args) {
        Set<String> set = new HashSet<>();
        set.add("apple");
        set.add("banana");
        set.add("cherry");

        String element = "banana";
        if (set.contains(element)) {
            Iterator<String> iterator = set.iterator();
            while (iterator.hasNext()) {
                String e = iterator.next();
                if (e.equals(element)) {
                    System.out.println("Element found: " + e);
                    break;
                }
            }
        } else {
            System.out.println("Element not found");
        }
    }
}

This will output the following:

Element found: banana

Keep in mind that this is just one way to get an element from a Set. Depending on your specific requirements, you may be able to use a different approach.

I hope this helps! Let me know if you have any questions.
