    Default Re: Getting error as "cannot be resolved to a type"

    Make sure the Encode class is in scope where you are trying to reference it.
    The formtting of the code makes it hard to read and understand. The {}s are not properly placed.
    Could be a tabs vs spaces being used to control indentations issue.
    If you don't understand my answer, don't ignore it, ask a question.
