StringTokenizer class in Java is used to break a string into tokens.
A StringTokenizer object internally maintains a current position within the string to be tokenized. Some operations advance this current position past the characters processed.
A token is returned by taking a substring of the string that was used to create the StringTokenizer object.
StringTokenizer(String str) : str is string to be tokenized. Considers default delimiters like new line, space, tab, carriage return and form feed. StringTokenizer(String str, String delim) : delim is set of delimiters that are used to tokenize the given string. StringTokenizer(String str, String delim, boolean flag): The first two parameters have same meaning. The flag serves following purpose. If the flag is false, delimiter characters serve to separate tokens. For example, if string is "hello geeks" and delimiter is " ", then tokens are "hello" and "geeks". If the flag is true, delimiter characters are considered to be tokens. For example, if string is "hello geeks" and delimiter is " ", then tokens are "hello", " " and "geeks".
