The JavaDoc for StringTokenizer.nextToken() shows that it returns a
String. Assuming you declared "int data[]", you need to put ints into
each element of data[]. How to convert a String to an int:
try {
String token = example.nextToken();
data[i] = Integer.parseInt(token);
} catch ( NumberFormatException nfe ) {
// Handle the error here.
}
Never used StringTokenizer before? Never heard of Integer with a
capital I? What's this NumberFormatException thing? Now's your chance
to read the JavaDoc that came with your JDK or IDE. Every time you
encounter a class that's new to you, read its JavaDoc. This is the best
way for you and the new class to become good friends.
