In this post, we will see how to convert an Array to Set in Java. You can use this class as SetUtils class and it's method as a utility method in your project.

import java.util.Arrays;
import java.util.HashSet;
import java.util.Set;


public class SetUtils {

    private SetUtils() {}

    /**
     * Creates a set from the array elements.
     *
     * @param array the array with the elements
     *
     * @return the set with the elements
     */
    @SafeVarargs
    public static < T > Set < T > asSet(T...array) {
        Set < T > set = null;
        if (array != null) {
            set = new HashSet < > (Arrays.asList(array));
        }
        return set;
    }
}
