Question

I write a small java tool and a at the beginning I have to parse a url. I would like to know, what you are thinking about my solution and if there is a better way?
Here are some examples:

aaa://username:password@server:port/dir/

aaa://server:port/dir/

aaa://server:port

Every kind of String is possible, if the user is not carefully. So it is possible, that my function get such a string

aaa://username:pass

too. But the string always starts witch aaa://.

Here is my code:

url = url.replaceFirst("aaa://", "");

String params[] = url.split("@");
if(params[0].compareTo("") != 0) {
    String paramsfst[] = params[0].split(":");
    if(params.length == 1) {
        if(paramsfst.length >= 1) {
            this.server = parsePort(paramsfst[0]);
            if(paramsfst.length == 2) {
                this.port = parsePort(paramsfst[1]);
            }
        }               
    } else {
        String paramssec[] = params[1].split(":");
        if(paramssec.length >= 1) {
            this.server = parsePort(paramssec[0]);
            if(paramssec.length == 2) {
                this.port = parsePort(paramssec[1]);
            }
        }
        if(paramsfst.length == 2) {
            this.username = paramsfst[0];
            this.password = paramsfst[1];   
        }
    }
    if(url.contains("/")) {
        this.path = url.substring(url.indexOf("/"), url.length() -1);   
    }

private String parsePort(String port) {
    int i = port.indexOf("/");
    if(i == -1) {
        return port;
    }
    return port.substring(0, i);
}

What do you think?

Have you looked at the URL class?

See here for an example.
