Question

Is there a better way to read tokens in a file in java?
I am currently using StringTokenizer for splitting the tokens. But it can be quite inefficient in most cases as you have to read token by token.

Thank you

If you look at StringTokenizer in the Java API you will notice that it recommends an alternative:

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.

If neither of these options suit your needs, you should take a look at Scanner, which also supports pattern matching:

  Scanner scanner= new Scanner(new File("example.txt"));
  while (scanner.hasNextLine()) {
      // do some stuff
  }
