    Default Read String to List<Integer> and back

    Hi there,

    I am looking for a good and reliable library to read a string to construct a list of Integers, Doubles, Booleans, etc.
    This library should be robust enough to handle faulty input from an inexperienced user.

    Example:
    input: "1, 2, 3, 4"
    output List<Integer> [1, 2, 3, 4]

    input: "1, 2, 3.6, 4"
    output List<Double> [1.0, 2.0, 3.6, 4.0]

    input: "true, true, false"
    output List<Boolean> [true, true, false]

    input: "[1, 2, 3]"
    output List<Integer> [1, 2, 3]

    input: "(1, 2, 3)"
    output List<Integer> [1, 2, 3]


    It would be really nice if such a library would already exist. Would save me an hour of writing it myself.
    So yeah, if you know of any reliable library please let me know, I would really appreciate.
    Thank you very much.

    Thread moved from 'What's wrong with my code'.

    Take a look at JSON (don't let the javascript in the acronym fool you, as it is just a simple way of representing variables, arrays, and maps as text). json.org has a library that reads/writes objects to and from String's. For instance, the JSONArray class can be used to do just that.
