In this article, we would like to show you how to add items to the HashSet in Java.

Quick solution:

xxxxxxxxxx
 
Set<String> animals = new HashSet<>();
animals.add("Dog");

Practical example

Edit

In this example, we add three elements to the animals HashSet using add() method.

xxxxxxxxxx
 
import java.util.*;
​
public class Example {
​
    public static void main(String[] args) {
        Set<String> animals = new HashSet<>();
​
        animals.add("Dog");
        animals.add("Cat");
        animals.add("Parrot");
​
        System.out.println(animals);  // [Parrot, Cat, Dog]
    }
}
