<html>
   <body>
      <form action = "main.jsp" method = "POST" target = "_blank">
         <input type = "checkbox" name = "maths" checked = "checked" /> Maths
         <input type = "checkbox" name = "physics" /> Physics
         <input type = "checkbox" name = "chemistry" checked = "checked" /> Chemistry
         <input type = "submit" value = "Select Subject" />
      </form>
   </body>
</html>

The above code will generate the following result −

 Maths  Physics  Chemistry

<html>
   <head>
      <title>Reading Checkbox Data</title>
   </head>
   <body>
      <h1>Reading Checkbox Data</h1>
      <ul>
         <li><p><b>Maths Flag:</b>

            <%= request.getParameter("chemistry")%>
            </p></li>
      </ul>
