                  if(request.getAttribute("Brand")!=null)

{   String Brand[]=(String[])request.getAttribute("Brand");
    for(String brand:Brand)
    {      sb.append("Brand=");
          sb.append(brand);
          sb.append("&&");
    }
   }
if(request.getAttribute("Flavour")!=null)
{
String Flavour[]=(String[])request.getAttribute("Flavour");
    for(String flavour:Flavour)
    {       
          sb.append(flavour);
          sb.append("&&");
    }
    sb.trimToSize();
    pageContext.setAttribute("sb", sb);
}
