import java.util.EnumSet;
import java.util.Iterator;

public class EnumSetAllOfTest {

  /**
   @param args
   */
  public static void main(String[] args) {

    EnumSet<Fruit> enumSet = EnumSet.allOf(Fruit.class);
    System.out.println(enumSet);
    
    Iterator<Fruit> it = enumSet.iterator();
    Fruit fruit = null;
    
    while (it.hasNext()) {
      fruit = it.next();
      System.out.println(fruit + "-->" + fruit.ordinal());
    }
    
  }

}
