}

Int counttokens ()
Count the number of times the tokenizer nexttoken method can be called before an exception is generated.
Boolean hasmoreelements ()
Returns the same value as the hasmoretokens method.
Boolean hasmoretokens ()
Test whether there are more available tags in the tokenizer string.
Object nextelement ()
Except that the declared return value is an object rather than a string, it returns the same value as the nexttoken method.
String nexttoken ()
Returns the next tag of the string tokenizer.
String nexttoken (string delim)
Returns the next tag in the string of this string tokenizer.
