我创建了一个帮助方法processURL()，它接受​​一个URL并返回一个包含查询标记（?）或井号（#）的所有内容的URL：

String processURL(String theURL) {
    int endPos;
    if (theURL.indexOf("?") > 0) {
        endPos = theURL.indexOf("?");
    } else if (theURL.indexOf("#") > 0) {
        endPos = theURL.indexOf("#");
    } else {
        endPos = theURL.length();
    }

    return theURL.substring(0, endPos);
}

String urlOne = "http://stackoverflow.com/questions/tagged/jav?#sort=featured&pageSize=50";
String urlTwo = "http://stackoverflow.com/questions/tagged/java#comments";

System.out.println(processURL(urlOne));
System.out.println(processURL(urlTwo));
