Overview
To create a radio button in HTML we will use <input type="radio"> tag. It contains name attribute.
<input type="radio" name="gender" value="Male" />Male
To read the radio button value in JSP, we will use the request object
<%= request.getParameter("radioButtonName") %>
getParameter() takes the name of the radio button. Another shortcut method to read radio button value is using param object
${param.radioButtonName}
Using param object we can read the radio button value.
