StreamTokenizer has bells and whistles to deal with parsing source code, including white space, comments and numbers. Building on the lessons gleaned from last month's article, learn how to convert human-readable text into machine-readable data using a StreamTokenizer in an actual application. (3,400 words) StreamTokenizer, 2 • When a StreamTokenizer the public member sval contains the String • When a number token is recognized, public member nval contains its value. • StreamTokenizer whitespace • StreamTokenizer the recognizes a word, representing the word. also ignores (blanks and tabs) and C, C++, and Java style comments by default.

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 readLine read all line in.

Java has no built-in methods for reading data of the form: 123 456,-4. You have to roll your own method. Use java.io.StreamTokenizer or java.util.StringTokenizer, perhaps in combination with readLine to get your data into strings.

Everything kept same except some renaming for following C# naming convention. And it also implements IEnumerable for foreach support - StreamTokenizer.cs StreamTokenizer.

You can use StreamTokenizer for this in a pinch. StreamTokenizer. 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.
