Regex

Pattern Matching

Named Matching

<syntaxhighlight lang="java">
private @Nullable String getToken(@Nonnull String responseURL) {</pre>
String patternString = "http://www.example.com/example#(token%3D(?<TOKEN>.+))%26otherstuff(.+%)";
Pattern pattern = Pattern.compile(patternString);
Matcher matcher = pattern.matcher(responseURL);
if(matcher.find()){
return matcher.group("TOKEN");
}
return null;
}
</syntaxhighlight>

Encoding

Base64 Encoding (Basic auth)

String base64encodedUsernameAndPassword = DatatypeConverter.printBase64Binary((username + ":" + password).getBytes());
webClient.addRequestHeader("Authorization", "Basic " + base64encodedUsernameAndPassword);

URL Parsing

List<NameValuePair> params = URLEncodedUtils.parse(new URI(url), "UTF-8");
