Hi Friend,

Try the following code:

<%@ taglib uri=""; prefix="c" %>
<%@ page import="java.util.*"%>
<% Random r=new Random();
int num = r.nextInt(100);
int pno=num-1;
int nno=num+1;
<form method="post">Random Number:<input type="hidden" name="number" value="<%=num%>" />
<input type="submit" value="Accept" />
<c:if test="${pageContext.request.method=='POST'}">Random number is: <%=num%>
<c:when test="${param.number%2==0}">It is an even number lies between <%=pno%> and <%=nno%>.
<br />
<c:otherwise>It is an odd number lies between <%=pno%> and <%=nno%>.
<br />
