and i have an error "incompatible types ,required:int, found:String" i wrote then this

<% int r= (int) request.getParameter("param");%>

but it doesnt work also...

Answer 1

request.getParameter("param") will return String.So you need to convert it to int.For that you need to do typecasting

like

<% int r=Integer.parseInt(request.getParameter("param"));%>

Answer 2

You need to use parseInt

<% int r=Integer.parseInt(request.getParameter("param"));%>
