      boolean[] sarr = (boolean[]) Array.newInstance(boolean.class, 3);

      Array.set(sarr, 0, true);
      Array.set(sarr, 1, false);
      Array.set(sarr, 2, true);
       for(int i=0;i<sarr.length;i++)
       {
            System.out.println("sarr["+i+"] = " + Array.get(sarr, i));
       }     
   }
}
