The java.io.StreamTokenizer.commentChar(int ch) method specifies that the character argument starts a single-line comment. All characters from the comment character to the end of the line are ignored by this stream tokenizer. Any other attribute settings for the specified character are cleared

You would have to use a StringBuffer to hold all the stuff and then do some parsing. Creates a stream tokenizer that parses the specified input stream. The stream tokenizer is initialized to the following default state: All byte values 'A' through 'Z', 'a' through 'z', and '\u00A0' through '\u00FF' are considered to be alphabetic.; All byte values '\u0000' through '\u0020' are considered to be white space. '/' is a comment character. Can you please tell me why StreamTokenizer makes my double numbers like 2.53 into two separate 2.0 and 53.0?.

To reset the default set of delimiters, we will employ the resetSyntax( ) method. The default set of delimiters is finely tuned for tokenizing Java programs and is thus too specialized for this example.

'/' is a comment character. Can you please tell me why StreamTokenizer makes my double numbers like 2.53 into two separate 2.0 and 53.0?. And how can i fix it so it gives me full number read from file?. public class StreamTokenizer extends Object. The StreamTokenizer class takes an input stream and parses it into "tokens", allowing the tokens to be read one at a time.

The different types of tokens that can be found are numbers, identifiers, quoted strings, and different comment styles. The class can be used for limited processing of source code of programming languages like Java, although it is nowhere near 12/3/2020 A StreamTokenizer object can be wrapped around an InputStream. In this case, when the StreamTokenizer reads bytes from the stream, the bytes are converted to Unicode characters by simply zero-extending the byte values to 16 bits. As of Java 1.1, a StreamTokenizer can be wrapped around a Reader to eliminate this problem. Java Code Examples for java.io.StreamTokenizer.

The StreamTokenizer class takes an input stream and parses it into "tokens", allowing the tokens to be read one at a time. The parsing process is controlled by a table and a number of flags that can be set to various states. The stream tokenizer can recognize identifiers, numbers, quoted strings, and various comment styles. StringTokenizer is a legacy class that is retained for compatibility reasons although its use is discouraged in new code. It is recommended that anyone seeking this functionality use the split method of String or the java.util.regex package instead.

The parsing process is controlled by a table and a number of flags that can be set to various states. The stream tokenizer can recognize identifiers, numbers, quoted strings, and various comment styles. The java.util.StringTokenizer class allows you to break a string into tokens. It is simple way to break string. It doesn't provide the facility to differentiate numbers, quoted strings, identifiers etc. like StreamTokenizer class.
