EnumSet Range 

The following example shows how to create an enum set containing all of the elements in the range defined by the two specified elements. The range specified is inclusive of elements. EnumSet provides the following APIs,

 - Returns enum set containing all of the elements in the range 
   defined by the two specified elements.

public class EnumSetRangeTest {

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

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