Java Scanner Input Length

Hello everybody, can anyone tell me how to find the length of an Scanner Input? Because I want to do a program, which is printing out the length of the typed name. Sorry for my bad English because I am a german. https://code.sololearn.com/c5gn6J16jqZj/?ref=app

Strings have a length() method you can use. Example/ String input = scannerName.nextLine(); input.length(); // this is the length of the String.
