Addition of Two Numbers JSP
Hi! Nice problem but you do not need to worry as you have made a very small mistake!
In your code you have defined the function in static format and anything, which is written in static, will print the value as it is given.
In your code you have written ?2 + 2 is $ {2 + 2}? in a body, so there is no chance of getting calculated value from it.
In JSP programming you can retrieve the value through Scriptlets <% %>.
Your program of Addition of two values in JSP would be as fellow:
JSP addition of two Numbers - Example Code
- - - - - - - - - - - - - - - - - - - - - - -
<%@ page language="java" import="java.util.*" %>
<html>
<head>
</head>
<body>
<h1>Hello World!</h1>
<%!
int i = 45;
int j = 30;
int Sum;
%>
<%
Sum = i + j;
out.println("The sum of " + i + " and " + j + " is =" + Sum); %>
</body>
</html>
