    select box problem

    Hjava
      I have a simple drop down box with the select item out of db
      like if the value in my db is i then the user will see two line of <option value="1">1</option>,
      is that a simple way to handle this problem?
      <select name="year">
                                              
                                              <option selected value="${found.year}"> <c:out value="${found.year}"/></option>
                                              <option  value="1">1</option>
                                              <option value="2">2</option>
                                              <option value="3">3</option>
                                              <option value="4">4</option>
                                              <option value="5">5</option>
                                              <option value="6">6</option>
                                          </select>
      I don't want to use the method
      <c:if test="${found.year=='1'}">
      <option value="1" selected>1</option>
      <c:if test="${found.year!='1'}">
      <option value="1" >1</option>
      since if the select list is long , like to 100 then the code will turn to every long , should be have a better way , is that right??

                              for (int i = 1; i <= 10; i++) {
                                  tyear.add(i);
                              }
          <select name="year">
          
                                                  <% for (Integer num : tyear) {
                                                                  String aY = Integer.toString(num);%>
                                                  <c:if test="${found.year==aY}">
                                                      <option selected value="${found.year}"> <c:out value="${found.year}"/></option>
                                                  </c:if>
                                                  <c:if test="${found.year!=aY}">
                                                      <option value="<%= aY%>"><% out.println(aY);%></option>
                                                  </c:if>
                                                  <%}%>
                                              </select>
