正则表达式拆分url实例代码

url: Http://www.baidu.com/love/java?lang=java
regex: (\w+):\/\/([^/:]+)(:\d*)?([^# ]*)

var url = "http://www.baidu.com:80/love/java?lang=java";
var patt1 = /(\w+):\/\/([^/:]+)(:\d*)?([^# ]*)/;
arr = url.match(patt1);
for (var i = 0; i < arr.length ; i++) {
    document.write(arr[i]);
    document.write("<br>");
}

        String url = "http://www.baidu.com:80/love/java?lang=java";
        Pattern pattern = Pattern.compile("(\\w+):\\/\\/([^/:]+)(:\\d*)?([^# ]*)");
        Matcher matcher = pattern.matcher(url);
        matcher.find();
        for (int i = 1; i <= matcher.groupCount(); i++){
            System.out.println(matcher.group(i));
        }
