Get checked Radio Button Value from JSP to Servlet

In HTML/JSP, 

<input type="radio" value="10" name="a">10 Records
<input type="radio" value="20" name="a">20 Records
<input type="radio" value="50" name="a">50 Records

In Servlet,

String val= request.getParameter("a");
System.out.println("Record is : "+val);

Variable val returns null .

check whether your form specifies the method post. please refer below

<form action="/Servlet" method="post">
     <input type="radio" value="10" name="a">10 Records
     <input type="radio" value="20" name="a">20 Records
     <input type="radio" value="50" name="a">50 Records 
     <input type = "submit" value = "submit"/>
</form>

then it should work.

     <input type="radio" value="20" name="a">20 Records
