Second Lesson on JSP
Now we are going to calculate "simple interest". First of all we have to create html page like ::
<%--
Document : interest
Created on : 30 Oct, 2012, 10:30:44 PM
Author : NESTED CODE
--%>
<%@page contentType="text/html" pageEncoding="UTF-8"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>JSP Page</title>
<script>
function checkNumber(f)
{
var a = window.event.keycode;
if(!(a>=48 && a<=57))
alert("Type a number between 0 and 9")
}
</script>
</head>
<body><br><br><center>
<form action="intjsp.jsp "><pre>
<h1>Principal :: <input type=text name=principle value=0 onkeypress="checkNumber(this.form)" ><br>
No. of Years :: <input type=text name=year value=0 onkeypress="checkNumber(this.form)" ><br>
Rate of Interest :: <input type=text name=interest value=0 onkeypress="checkNumber(this.form)" ><br>
<br>
<input type=submit value="Submit"></h1>
</pre></form></center>
</body>
</html>
Now we have to create the page "intjsp.jsp" to calculate interest
Code for this "intjsp.jsp" page ::
Document : intjsp
Created on : 30 Oct, 2012, 10:41:10 PM
Author : NESTED CODE
--%>
<%@page contentType="text/html" pageEncoding="UTF-8"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>JSP Page</title>
</head>
<body><br><br><center><pre><H1>
<%
String ns= request.getParameter("principle");
String ns1= request.getParameter("year");
String ns2= request.getParameter("interest");
int n1=Integer.parseInt(ns);
int n2=Integer.parseInt(ns1);
int n3=Integer.parseInt(ns2);
double si=((n1*n2*n3)/100);
double x;
x=n1+si;
%>
<%
out.println("Principal= "+n1);
out.println(" Years= "+n2);
out.println(" Rate of Interest= "+n3);
out.println("<br> ");
out.println(" Simple Interest= "+si);
out.println(" Simple Interest= "+x);
%>
</H1>
</pre>
</center>
</body> </body>
</html>
The Outpur will be like ::
