Java 小程序

import java.util.Scanner;

public class next {

public static void main(String[] args) {

System.out.print("请依次输入贷款总额，月利率，年数");

Scanner sc = new Scanner(System.in);

double yzfje = 0;

yzfje = (dkze*ylv/100)/(1-1/Math.pow(1+ylv,ns*12));

System.out.println("月支付金额为："+yzfje);

}

}

谁能给个JAVA的小程序代码，越小越好！

这是我晓得的最简单的java小程序代码了你可以看看:

package com.kenki.emp;

import javax.servlet.*;

import javax.servlet.http.*;

import java.io.*;

import java.util.*;

import java.sql.SQLException;

import java.sql.*;

public class emp extends HttpServlet {

private static final String CONTENT_TYPE = "text/html; charset=GBK";

//Initialize global variables

public void init() throws ServletException {

}

//Process the HTTP Get request

public void doGet(HttpServletRequest request, HttpServletResponse response) throws

ServletException, IOException {

response.setContentType(CONTENT_TYPE);

PrintWriter out = response.getWriter();

String code = request.getParameter("code");

String name = request.getParameter("name");

String pay = request.getParameter("pay");

System.out.println("empcode:" + code);

System.out.println("name:" + name);

System.out.println("pay:" + pay);

//创建驱动

new com.microsoft.jdbc.sqlserver.SQLServerDriver();

String strd =

"jdbc:microsoft:sqlserver://localhost:1433;databasename=emp_dates";

String username = "sa";

String pws = "";

try {

java.sql.Connection conn = java.sql.DriverManager.getConnection(

strd, username, pws);

String strs = "insert into emp values(?,?,?)";

java.sql.PreparedStatement pre = conn.prepareStatement(strs);

pre.setString(1, code);

pre.setString(2, name);

pre.setString(3, pay);

pre.execute();

pre.close();

conn.close();

//重定向至查询页面

out.println("成功保存！！");

response.sendRedirect("emp.html");

} catch (SQLException ss) {

ss.printStackTrace();

response.sendRedirect("/WebModule1/error.html");

}

}

//Process the HTTP Post request

public void doPost(HttpServletRequest request, HttpServletResponse response) throws

ServletException, IOException {

doGet(request, response);

}

//Clean up resources

public void destroy() {

}

}
