The job of StreamTokenizer is to recognize sequences of characters that can categorized as identifiers, numbers, quoted strings, and comments. To do this, you must tell the StreamTokenizer how to categorize each character it might encounter: white space, alphabetic, numeric, string quote, and comment.

The StreamTokenizer class provides the method nextToken, which skips whitespace, and returns an integer value indicating the type of the next token in the input.It also sets the StreamTokenizer field ttype to the same value. For tokens that are words, the nextToken method sets the sval field of the StreamTokenizer to the actual value of the token, and for tokens that are I wrote a grogram to read a text file in. for a line, read the first word in using StreamTokenizer and then the second char(a ":") and then using readLine to read the rest of the line in. the following loop is surposed to do this and the 1st iteration works well but then the StreamTokenizer doesn't work and the … StreamTokenizer.
