The same output can be generated with this code, which uses a regularĮxpression to parse all four tokens at once: ![]() Scanner s = new Scanner(input).useDelimiter("\\s*fish\\s*") String input = "1 fish 2 fish red fish blue fish" ThisĮxample reads several items in from a string: The scanner can also use delimiters other than whitespace. Scanner sc = new Scanner(new File("myNumbers")) Tokens may then be converted into values of different types using theįor example, this code allows a user to read a number fromĪs another example, this code allows long types to beĪssigned from entries in a file myNumbers: A simple text scanner which can parse primitive types and strings usingĪ Scanner breaks its input into tokens using aĭelimiter pattern, which by default matches whitespace. ![]()
