java通过一个数字找到匹配的手机号码怎么写代码
比如你拿到的数字是 number, 所有手机号码为 tele_nums,一个手机号码为tele_num;
。。。
String test = String.vlaueOf(number);
for(...) { //获取单个手机
if(tele_num.contains(test)) {
...
...这里面就已经过滤了
}
}
小女子跪求:如何用java实现电话号码查找
话说~~
如此大的测试集和苛刻的约束条件的随即生成,如果要用JAVA编译器来完成,那是件相当麻烦的事情,估计问问数据库方面的专家比较好.
编写程序,提供图形交互界面进行号码速查:
这个功能用JAVA就很好做了,好象楼上说的,Swing,DAO方面,如果是用SQL语句的话,做个模糊查询就可以了.
"界面要求美观大方,可参考金山词霸界面。"估计Swing还不够...
这个项目如果我做出来了,拿个界面做个模板去卖,估计可以换1个星期的烟钱.
java程序代码实现手机号码归属地查询,求源码?
import java.io.IOException;
import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;
import org.jsoup.select.Elements;
public class Test {
public static void main(String[] args) throws IOException {
String mobile = "手机号码";
String url = ";mobile=%s";
url = String.format(url, mobile);
Document doc = Jsoup.connect(url).get();
Elements els = doc.getElementsByClass("tdc2");
System.out.println("归属地:" + els.get(1).text());
System.out.println("类型:" + els.get(2).text());
System.out.println("区号:" + els.get(3).text());
System.out.println("邮编:" + els.get(4).text().substring(0, 6));
}
}
