问如何在不重新加载JSP页面的情况下，通过单击next/previous按钮逐个打印数据(arraylist的对象)？

<%  ArrayList<QuesnBean> list =new ArrayList<QuesnBean>();

list = (ArrayList<QuesnBean>)request.getAttribute("question"); 
int i=0, l=list.size();
    for(QuesnBean qbean : list)
    {
     qbean = list.get(i);

         out.print("<br><br> Q.No: "+ (i+1) +"  ");
         out.println(qbean.getQuesn()+"<br>");
         out.println("<br> <input type='radio' name='o1'> "+qbean.getOp1());
         out.println("<br> <input type='radio' name='o1'> "+qbean.getOp2());
         out.println("<br> <input type='radio' name='o1'> "+qbean.getOp3());
     out.println("<br> <input type='radio' name='o1'> "+qbean.getOp4());

         if(i<=l){
            i++;
            }
    }
