Creates an enum set initially containing the specified element.

Usage

From source file:Numbers.java

public static void main(String[] args) {

    EnumSet<Numbers> set1 = EnumSet.of(Numbers.FOUR);

    System.out.println("Set1:" + set1);

    // create a set2 which has all elements that set1 doesn't have
    EnumSet<Numbers> set2 = EnumSet.complementOf(set1);

    System.out.println("Set2:" + set2);

}

From source file:Numbers.java

public static void main(String[] args) {

    // create a set
    EnumSet<Numbers> set;//from  w w  w . j a  v a2  s  .  c o  m

    // 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);
}
