Streamtokenizer typ

Does anyone know how to find the data type of st.nextToken in the code below? I can't use streamTokenizer's TT_WORD or TT_NUMBER b/c need to parse words like G7790 that have both #s and letters and streamTokenizer gets confused. Need something specific to stringTokenizer. Searched Sun's page w/ no luck. TIA

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.

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 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.

However, while the StreamTokenizer has a lineno() method to find which line the tokenizer is at, there is no method to find the character offset within that line. I am hoping that somehow there is a way to get this offset using the available functions in either StreamTokenizer or BufferedReader, the input to the StreamTokenizer constructor.

After a call to the nextToken method, this field contains the type of the token just read. StreamTokenizer(InputStream) Creates a stream tokenizer that parses the specified input stream.

try { int type = StreamTokenizer.TT_WORD; while (type != StreamTokenizer. TT_EOF) { type = tok.nextToken(); if (type == StreamTokenizer.TT_WORD) { String str

In general, it is recommended that the passed in StreamTokenizer should have had resetSyntax() done to it, so that numbers are returned as entered as tokens of type String , though this code will cope as best it … StreamTokenizer to use. private java.util.Stack stack Stack used for token push-back Constructor Summary; StringTokenizer(java.lang.String inputFileName) Initialize _st to read from a input Reader file with the given input file name.

System.out.println("The file type is: " +file_name.substring( file_name.indexOf('.')+1)); Pass the BufferedReader to StreamTokenizer object.

Java try-catch block Java try block. Java try block is used to enclose the code that might throw an exception. It must be used within the method. If an exception occurs at the particular statement of try block, the rest of the block code will not execute. So, it is r Dec 13, 2020 · The tokenization method is much simpler than the one used by the StreamTokenizer class. The StringTokenizer methods do not distinguish among identifiers, numbers, and quoted strings, nor do they recognize and skip comments. Java String Split: Splits this string around matches of the given regular expression.

A StreamTokenizer similar to Java's. This breaks an input stream (coming from a TextReader) into Tokens based on various settings. The settings are stored in the TokenizerSettings property, which is a StreamTokenizerSettings instance.

These tokens will be ttype : This contains the type of the token which has been read. Using the StreamTokenizer you don't have to be afraid of high memory cost.
