StringTokenizer (String str, String delim, boolean returnValue) creates StringTokenizer with specified string, delimeter and returnValue. A string tokenizer can use multiple distinct delimiters, and the delimiters are packaged as a string to the tokenizer’s constructor method. The split method splits a string into multiple strings based on the delimiter provided and returns the array of strings computed by splitting this string around matches of the given regular expression. Delimiter characters themselves will not be treated as * tokens. Since we didn’t specify the delimiter, automatically the default delimiters are ” tnrf”: the space character, the tab character, the newline character, the carriage-return character, and the form-feed character.
