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>
