doubt in getParameter()

Hi everybody, i have created one jsp page and have written the server side code in servlet.

In the jsp page i have declared two radio button like this
<input type="radio" name="sex" value="male">Male<br />
<input type="radio" name="sex" value="female">Female<br />

here name parameter is a radio button group name. so we can select any one radio button at a time.

Now i write the servlet code for reading the textfield value only.

But my question is can i read the radio button value/name?(you assume that if i click the male radio button in my jsp loginform what value/name returns to getParameter() method).

2. how to rectify which radio button is checked? to write the condition(male or female) for radio button in servlet code?

please any one tell me detailed answer for this question. because i am very confused.

you can try this as usual like request.getParameter("sex");

then coming to your concern, we are able to select only one button at time. so it doesnot make any confusion.

I think it clarifies your concern

String sexL = (String )request.getParameter("sex");
//action if input radio button is female
