从数据库得到号码：pcode=rs.getString( "Phone ");
之后应该如何处理能显示的时候隐去中间四位啊？
谢谢大家啦！
------解决方案--------------------
pcode=rs.getString( "Phone ");
pcode=pcode.substring(0,3)+ '**** '+pcode.substring(7);
pcode= '13912345678 ';
pcode=pcode.substring(0,3)+ '**** '+pcode.substring(7);
139****5678

lhfzd2004(风之刀) 的这个方法不错。
pcode=rs.getString( "Phone ");
pcode=pcode.replaceAll(pcode.subString(3,4), "**** ");
------解决方案--------------------
我该了代码，如下：
while(rs.next()){
pcode=rs.getString( "Phone ");
pcode=pcode.substring(0,3)+ '**** '+pcode.substring(7);
src=src+pcode+ ", ";
}
但是报错啦：

这是什么原因啊？
------解决方案--------------------
找不到jsp编译后的类,
建议把cj1.jsp随便改动下让Tomcat重新加载,
或者清空Tomcat主目录\work\Catalina\localhost\项目文件夹\org\apache\jsp\ly365\
------解决方案--------------------
subString
classNotFound跟本问题无关
------解决方案--------------------
标记！
