Use is subject to license terms.

There are multiple constructors available for StringTokenizer, one of it accepts a delimiter apart from the input String. We can use a FileReader object or any other Reader object as tutorkal data source.

Some operations advance this current position past the characters processed. Note that if delim is nullthis constructor does not throw an exception. Returns the absolute value of a long value.

From the above code, we basically just create a new StringTokenizer object and make use of one of the class constructor to initialize the String to be tokenized. Stringtokenier class allows you to break a string into tokens.

Thank u for giving this information.

The nextToken method actually return stringtpkenizer current token and then point to the next token if there are still available on the buffer.
