This is an example of how to get and use a StreamTokenizer from a BufferedReader. The StreamTokenizer class takes an input stream and parses it into “tokens”, allowing the tokens to be read one at a time. Getting a StreamTokenizer from a BufferedReader implies that you should:
- Create a new BufferedReader using a FileReader.
- Create a new StreamTokenizer that parses the given bufferedReader.
- Iterate over the tokens of the tokenizer and print their values.
Let’s take a look at the code snippet that follows:
package com.javacodegeeks.snippets.core;
import java.io.BufferedReader;
import java.io.FileReader;
import java.io.StreamTokenizer;
class StreamToeknizerExample {
public static void main(String args[]) throws Exception {
FileReader fileReader = new FileReader(args[0]);
BufferedReader buffReader = new BufferedReader(fileReader);
StreamTokenizer streamTokenizer = new StreamTokenizer(buffReader);
streamTokenizer.ordinaryChar('.');
streamTokenizer.wordChars(''', ''');
while (streamTokenizer.nextToken() != StreamTokenizer.TT_EOF) {
switch (streamTokenizer.ttype) {
case StreamTokenizer.TT_WORD:
System.out.println(streamTokenizer.lineno() + ") " + streamTokenizer.sval);
break;
case StreamTokenizer.TT_NUMBER:
System.out.println(streamTokenizer.lineno() + ") " + streamTokenizer.nval);
break;
default:
System.out.println(streamTokenizer.lineno() + ") " + (char) streamTokenizer.ttype);
}
}
fileReader.close();
}
}
Output:
