Usage:


  public static void main(String[] args) {
    SparseBitmap sp1 = SparseBitmap.bitmapOf(1, 2, 100, 150, 1000, 123456);

    for (int i : sp1)
      System.out.print(i + " ");
    System.out.println();

    SparseBitmap sp2 = SparseBitmap.bitmapOf(1, 2, 3, 1000, 123456, 1234567);

    for (int i : sp2)
      System.out.print(i + " ");
    System.out.println();

    SparseBitmap sand = sp1.and(sp2);

    System.out.println("and:");

    for (int i : sand)
      System.out.print(i + " ");
    System.out.println();
    
    SparseBitmap sor = sp1.or(sp2);
    
    System.out.println("or:");

    for (int i : sor)
      System.out.print(i + " ");
    System.out.println();

  }
