The string tokenizer class allows an application to break a string into tokens. The tokenization method is much simpler than the one used by the StreamTokenizer class. The StringTokenizerUtil methods do not distinguish among identifiers, numbers, and quoted strings, nor do they recognize and skip comments.
The set of delimiters (the characters that separate tokens) may be specified either at creation time or on a per-token basis.
An instance of StringTokenizerUtil behaves in one of two ways, depending on whether it was created with the returnTokens flag having the value true or false:
false, delimiter characters serve to separate tokens. A token is a maximal sequence of consecutive characters that are not delimiters. true, delimiter characters are themselves considered to be tokens. A token is thus either one delimiter character, or a maximal sequence of consecutive characters that are not delimiters. A StringTokenizerUtil 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 StringTokenizerUtil object.
The following is one example of the use of the tokenizer. The code:
StringTokenizerUtil st = new StringTokenizerUtil("this is a test"); while (st.hasMoreTokens()) { println(st.nextToken()); } prints the following output:
