index.jsp

<html>
<head>
<title>EX-23</title>
<style>
.abc
{
background:#ababff;
position:absolute;
top:2in;
hieght:200px;
width:400px;
left:5in;
border-style:solid;
}
</style>

</head>
<body>

<div class="abc" id="f1">
<br>
<form method="get" action="/Ex23/bipinrupadiya.blogspot.com">
<table align="center">
<tr>
<td colspan=2 align=center><h3>Simple Interest</h3><hr>
</td>
</tr>
<tr>
<td>Amount : </td>
<td><input type="text" name="p"></td>
</tr>
<tr>
<td>Rate :</td>
<td><input type="text" name="r"></td>
</tr>
<tr>
<td>Time :</td>
<td><input type="text" name="n"></td>
</tr>

<tr>
<td colspan=2 align=center>
<hr>
<input type="submit" value="Calculate">
<input type="reset" value="Clear">
</td>
</tr>
</table>
</form>
</div>
</body>
</html>

Ex23.java

package bsr;
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
import javax.servlet.annotation.WebServlet;

/** Ex23 simple Interest. by Bipin S rupadiya */

@WebServlet("/bipinrupadiya.blogspot.com")
public class Ex23 extends HttpServlet
{
public void doGet(HttpServletRequest request,HttpServletResponse response) throws IOException,ServletException
{
response.setContentType("text/html");
PrintWriter out=response.getWriter();

float p=Float.parseFloat(request.getParameter("p"));
float r=Float.parseFloat(request.getParameter("r"));
float n=Float.parseFloat(request.getParameter("n"));
float i=(p*r*n)/100;
out.println("<br><h1>Simple Interest will be : "+i);
}
}

2. Using Java Beans (Form Beans)

index.jsp

<html>
<head>
<title>EX-23</title>
<style>
.abc
{
background:#ababff;
position:absolute;
top:2in;
hieght:200px;
width:400px;
left:5in;
border-style:solid;
}
</style>

</head>
<body>

<div class="abc" id="f1">
<br>
<form method="POST" action="result.jsp">
<table align="center">
<tr>
<td colspan=2 align=center><h3>Simple Interest</h3><hr>
</td>
</tr>
<tr>
<td>Amount : </td>
<td><input type="text" name="p"></td>
</tr>
<tr>
<td>Rate :</td>
<td><input type="text" name="r"></td>
</tr>
<tr>
<td>Time :</td>
<td><input type="text" name="n"></td>
</tr>

<tr>
<td colspan=2 align=center>
<hr>
<input type="submit" value="Calculate">
<input type="reset" value="Clear">
</td>
</tr>
</table>
</form>
</div>
</body>
</html>

result.jsp

<html>
<head>
<title>EX-23</title>
<style>
.abc
{
background:#ababff;
position:absolute;
top:2in;
hieght:200px;
width:400px;
left:5in;
border-style:solid;
}
</style>

</head>
<BODY>
<CENTER>

<jsp:useBean id="si" class="bsr.SimpleIntrest" />

<jsp:setProperty name="si" property="*" />

<div class="abc" id="f1">
<br>
<table width="50%" align="center">
<tr>
<th colspan=2><h3> Simple Interest</h3><hr></th>
</tr>
<tr>
<td>Amount : </td>
<td><jsp:getProperty name="si" property="p" /></td>
</tr>
<tr>
<td>Rate :</td>
<td><jsp:getProperty name="si" property="r" /></td>
</tr>
<tr>
<td>Time :</td>
<td><jsp:getProperty name="si" property="n" /></td>
</tr>
<tr>
<td>Interest :</td>
<td><jsp:getProperty name="si" property="intrest" /></td>
</tr>
<tr>
<th colspan=2> <hr><a href="index.jsp">Home</a></th>
</tr>
</table>
</form>
</div>
</body>
</html>

SimpleIntrest.java [ JavaBean ]

package bsr;
public class SimpleIntrest
{
private float p=1;
private float r=1;
private float n=1;

// Principal Amount
public float getP()
{
return(p);
}
public void setP(float v)
{
this.p = v;
}

// Rate of Interest
public float getR()
{
return(r);
}
public void setR(float v)
{
this.r = v;
}

// Number of Years
public float getN()
{
return(n);
}
public void setN(float v)
{
this.n = v;
}

//Calculate Interest
public float getIntrest()
{
return((p*r*n)/100);
}
}
