JSP求和计算

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+"/";

%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<html>

  <head>

    <base href="<%=basePath%>">

    <title>求和</title>

    <meta http-equiv="pragma" content="no-cache">

    <meta http-equiv="cache-control" content="no-cache">

    <meta http-equiv="expires" content="0">

    <meta http-equiv="keywords" content="keyword1,keyword2,keyword3">

    <meta http-equiv="description" content="This is my page">

    <!--

    <link rel="stylesheet" type="text/css" href="styles.css">

    -->

  </head>

  <body>

  <!-- 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">

<html>

  <head>

    <base href="<%=basePath%>">

    <title>求和</title>

    <meta http-equiv="pragma" content="no-cache">

    <meta http-equiv="cache-control" content="no-cache">

    <meta http-equiv="expires" content="0">

    <meta http-equiv="keywords" content="keyword1,keyword2,keyword3">

    <meta http-equiv="description" content="This is my page">

    <!--

    <link rel="stylesheet" type="text/css" href="styles.css">

    -->

    <%!

    //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) %>

  </body>

</html>
