      while(lowerRange < higherRange) 
      {
         boolean flag = false;
         for(int a = 2; a <= lowerRange / 2; ++a) 
         {
            if(lowerRange % a == 0)
            {
               flag = true;
               break;
            }
         }
         if(!flag && lowerRange != 0 && lowerRange != 1)
             System.out.print(lowerRange + " ");
         ++lowerRange;
      }
   }
}
