Windows_Phone_7_详解

C# public static List<string> GeneratePhoneNumber(int number) { Random rand = new Random(); List<string> str_phone = new List<string>(); string phoneNumber = "1"; // 手机号第一位为 1 for (int i = 0; i < number; i++) { for (int i = 0; i < 7; i++) { phoneNumber += rand.Next(0, 10).ToString(); // 生成随机数 } phoneNumber = phoneNumber.Insert(4, "****"); // 格式 str_phone.Add(phoneNumber); } return str_phone; }优化代码

while ( ifsW >> id && ifsW >> name && ifsW >> sex && ifsW >>phone) { Wnum++; }phone读入不进去怎么办

String sql = "update manager set password='"+password+"',age="+age+",phone='"+phone+"',address='"+address+"' where username='"+username+"'";这个sql语句哪里出错了

Java中定义Phone类，有品牌，颜色，价格属性，价格范围在200～8000，有打电话发短信的方法，创建对象输出Phone所有信息

讲解一下这段代码:ListPhoneServlet： package Session01; import javax.servlet.ServletException; import javax.servlet.annotation.WebServlet; import javax.servlet.http.HttpServlet; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import java.io.IOException; import java.io.PrintWriter; import java.util.ArrayList; @WebServlet("/listPhones") public class ListPhoneServlet extends HttpServlet { @Override protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException { resp.setContentType("text/html;charset=utf-8"); PrintWriter out = resp.getWriter(); out.println("
