StringTokenizer

[Fisher Daniel]

Dear all,
I have code like this
public class Test
{
public static void main(String[] args)
{
String temp = "07.00.00.00";
StringTokenizer st = new StringTokenizer(temp, ".00");
String data = st.nextToken();
System.out.println("data = " + data);
}
}
The output of this is 7.
Why is this? Because i think this will output 07 instead of 7....

Hi Fisher,
I'm afraid StringTokenizer is never going to return "07" as a single token with the String "07.00.00.00" and a delimiter String of ".00" (which is redundant since ".0" would accomplish the same thing). The constructor you used causes the tokenizer to discard all delimiters. So you only have one token: "7". Now you can use a constructor that returns delimiters as tokens:

        StringTokenizer st = new StringTokenizer(temp, ".00", true);

But that will return "0" for the first token, "7" for the second, "." for the third, etc.
If you change the delimiter to "." then you will get back the tokens "07", "00", "00", and "00".
Hope this helps,
Michael Morris

If what you want is to consider the string ".00" as a single delimiter, try

    String[] fields = temp.split("\\.00");
    for (int i = 0; i < fields.length; i++)
        System.out.println("field " + i + ": " + fields[i]);

Note that '.' is a special character as far as regular expressions are concerned (see API for the split() method), so you need \\ to escape it.
I don't know if that's what you were looking for, but it's worth a try...
