how to show a specific value in an option

Hi I am using an option in order to help the user to select a particular country. What I need is that if a user needs to edit a specific record the option should show the country name which the user had entered before

Here is my code

<td>
                  <select name="COUNTRY" class="textfield">

            <option value='0' selected> 'Please select one'</option>
<%
                        for(int key_index = 0; key_index < country_keys.length; key_index++) {
                              String next_key = (String)country_keys[key_index];
                              String next_value = (String)countries.get(next_key);
                              String selected_country = "";
                              if(selected_event.getCountry() == (null) || selected_event.getCountry() == "") { selected_country = "selected"; }
                              else { selected_country = "";}
%>
                              <option value="<%= next_key %>" <%= selected_country %>><%= next_value %></option>
<%                        } %>
                  </select>
            </td>

In this example if there is a value for selected_event.getCountry than the option should show that value, in other words it should be selected. Right now it shows the last country by default

Any help will be greatly appreciated

As a pure guess:

<td>
<select name="COUNTRY" class="textfield">

<option value='0' selected> 'Please select one'</option>
<%
for( int key_index = 0; key_index < country_keys.length ; key_index++ )
{
String next_key = (String)country_keys[key_index];
String next_value = (String)countries.get(next_key);
String selected_country = "";
if( selected_event.getCountry() != (null) && selected_event.getCountry().equals( next_value ) )
{
selected_country = "selected";
}
else
{
selected_country = "";
}
%>
<option value="<%= next_key %>" <%= selected_country %>><%= next_value %></option>
<%
}
%>
</select>
</td>

it was this line:

if( selected_event.getCountry() != (null) && selected_event.getCountry().equals( next_value ) )

that I changed...

It probably should be:

if( selected_event.getCountry() != (null) && selected_event.getCountry().equals( next_key ) )

But you don't say exactly what selected_event is...

I have actually stored the countries in a LinkedHashMap

LinkedHashMap countries = (LinkedHashMap)request.getAttribute("COUNTRIES");

next_key = key of hashmap
next_value = value of hashmap

Sorry it was a typo the real code was like this

<td>
<select name="COUNTRY" class="textfield">

<option value='0' selected> 'Please select one'</option>
<%
for( int key_index = 0; key_index < country_keys.length ; key_index++ )
{
String next_key = (String)country_keys[key_index];
String next_value = (String)countries.get(next_key);
String selected_country = "";
if( selected_event.getCountry() == (null) && selected_event.getCountry().equals("") )
{
selected_country = "";
}
else
{
selected_country = "selected";
}
%>
<option value="<%= next_key %>" <%= selected_country %>><%= next_value %></option>
<%
}
%>
</select>
</td>
