countTokens()
Calculates the number of times that this tokenizer's nextToken method can be called before it generates an
exception. |
boolean |
hasMoreElements()
Returns the same value as the hasMoreTokens method. |
boolean |
hasMoreTokens()
Tests if there are more tokens available from this tokenizer's string. |
java.lang.Object |
nextElement()
Returns the same value as the nextToken method, except
that its declared return value is Object rather than
String . |
java.lang.String |
nextToken()
Returns the next token from this string tokenizer. |

public StringTokenizer(java.lang.String str)
" \t\n\r\f"
: the space character,
the tab character, the newline character, the carriage-return character,
and the form-feed character. Delimiter characters themselves will not be
treated as tokens.
str
- a string to be parsed.public StringTokenizer(java.lang.String str, java.lang.String delim)
delim
argument are the delimiters for separating
tokens. Delimiter characters themselves will not be treated as tokens.
str
- a string to be parsed.delim
- the delimiters.public StringTokenizer(java.lang.String str, java.lang.String delim, boolean returnDelims)
delim
argument are the delimiters for separating
tokens.
If the returnDelims
flag is true
, then the
delimiter characters are also returned as tokens. Each delimiter is
returned as a string of length one. If the flag is false
,
the delimiter characters are skipped and only serve as separators between
tokens.
Note that if delim is null, this constructor does not throw an exception. However, trying to invoke other methods on the resulting StringTokenizer may result in a NullPointerException.
