Check If an Element Exists in Java LinkedHashSet Example

In the following example, we are checking whether LinkedHashSet contains a "Paris" city object or not.

package com.javaguides.collections.linkedhashsetexamples;

import java.util.LinkedHashSet;
import java.util.Set;

public class LinkedHashSetSimpleOperationsExample {
    public static void main(String[] args) {
        Set < String > popularCities = new LinkedHashSet < > ();

        popularCities.add("London");
        popularCities.add("New York");
        popularCities.add("Paris");
        popularCities.add("Dubai");

        // Check if the HashSet contains an element
        String cityName = "Paris";
        if (popularCities.contains(cityName)) {
            System.out.println(cityName + " is in the popular cities set.");
        } else {
            System.out.println(cityName + " is not in the popular cities set.");
        }
    }
}

Output

Paris is in the popular cities set.
