我分特~~ StringTokenizer ~~java的BUG~~?

<%@ page contentType="text/html;charset=gb2312"%>
<%@ page import="java.util.StringTokenizer"%>

<%
String str= "阿克苏克苏的阿[_分页_]克苏发喀什分发达广泛喀什的[_分页_]阿克苏的的阿克苏的";
out.print(str+"<br><br>");
StringTokenizer st = new StringTokenizer(str,"[_分页_]");
String[] str_t = new String[st.countTokens()];
while(st.hasMoreTokens()){
out.print(st.nextToken()+"<br>");
}
%>

这应该算标准的StringTokenizer用法吧~~大家猜猜结果~~注意看str中间有个单独的“分”字哦~~
