What is StreamTokenizer in Java?
The StreamTokenizer class takes an input stream and parses it into “tokens”, allowing the tokens to be read one at a time. The stream tokenizer can recognize identifiers, numbers, quoted strings, and various comment styles.
What is string tokenization?
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 StringTokenizer methods do not distinguish among identifiers, numbers, and quoted strings, nor do they recognize and skip comments.
What is the purpose of StringTokenizer class?

The parsing process is controlled by a table and a number of flags that can be set to various states. The stream tokenizer can recognize identifiers, numbers, quoted strings, and various comment styles.
What does the ttype field in streamtokenizer do?
The ttype field contains the type of the token just read. It could be TT_EOF, TT_EOL, TT_NUMBER, TT_WORD. However, for a quoted string token, its value is the ASCII value of the quote character.
Which is an example of a stringtokenizer in Java?
