You can do this:
<% String variable = request.getParameter("brazil"); %>
or
<% String variable = request.getParameterValues("brazil")[0];%>
At the end, the string variable has the value "carnival".
When you use "<% String variable = request.getParameter("brazil");
%>", you get only one value.
The method "getParameterValues" returns all the values in an array of
strings. In the example, we want only one value, then, we get the first
element of the array.
