已知两个数的值，如何求和并输出？
<%@ page language="java" import="java.util.*,java.text.*" contentType="text/html;charset=utf-8" %>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";

<!-- 两个数的求和计算 -->
<%
int numA=4;
int numB=5;
int result=numA+numB;
%>
两个数的和是<%=result %>
</body>
</html>
封装成函数
<%@ page language="java" import="java.util.*,java.text.*" contentType="text/html;charset=utf-8" %>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%><!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

//计算两个数和的算法
int computeNum(int num1,int num2){
return num1+num2;}
%>
</head> <body>
<!-- 两个数的求和计算 -->
两个数的和是<%=computeNum(5,8) %>
