EnumSet.of(E e) has the following syntax.
public static <E extends Enum <E>> EnumSet <E> of(E e)
In the following code shows how to use EnumSet.of(E e) method.
/*from w w w.j a v a2s.c o m*/ import java.util.EnumSet; enum Numbers { ONE, TWO, THREE, FOUR, FIVE }; public class Main { public static void main(String[] args) { // create a set EnumSet<Numbers> set; // add one element set = EnumSet.of(Numbers.FIVE); System.out.println(set); // add another element which replaces the previous set = EnumSet.of(Numbers.THREE); System.out.println(set); } }
The code above generates the following result.
