Hi,

I am getting a compilation warning at the statement
Enumeration<String> params = (Enumeration<String>)request.getParameterNames();

I am facing problem in removing this warning.

I don't want to use @SuppressWarnings("unchecked")

Can anyone please help in removing this warning?

I see two options. The first is to change request.getParameterNames() to return Enumeration<String> instead of Enumberation assuming that getParameterNames always returns Strings.
The other is to use a wild card enumeration instead of a Enumeration<String>. Since all objects can be converted to Strings it will allow you to use the Enumeration without getting any class cast exceptions

Enumeration<?> params = request.getParameterNames();
while (params.hasMoreElements())
{
    String value = params.nextElement().toString();
}
