JSP Retrieve checkbox values

1)checkbox.jsp:

<html>
<body>
<form method="post" action="../Action" >
Select Languages:<br>
<input type="checkbox" name="lang" value="C/C++">C/C++<br>
<input type="checkbox" name="lang" value="JAVA">Java<br>
<input type="checkbox" name="lang" value="C#">C#<br>

2)In Action class, use the following code:

if(request.getParameter("lang")!=null){
String st[]=request.getParameterValues("lang");
out.println("You have selected:");
for(int i=0;i<st.length;i++){
    out.println(st[i]);
