java.io.StreamTokenizer.TT_NUMBER: Floating or Integer?

is there a way to find if the value parsed and returned by java.io.StreamTokenizer.nval (e.g. 200) was an integer or a floating number ?

Thanks

Edited:

I want to be able to know if the input was '200' or '200.0'.

Solution

  • I don't think it is possible with StringTokenizer, it's too old. You can use Scanner to do the job:

    Scanner fi = new Scanner("string 200 200.0");
fi.useLocale(Locale.US);

while (fi.hasNext()) {
    if (fi.hasNextInt()) {
        System.out.println("Integer: " + fi.nextInt());
    } else if (fi.hasNextDouble()) {
        System.out.println("Double: " + fi.nextDouble());
    } else {
        System.out.println("String: " + fi.next());
    }  
}
