We have also provided links to examples of each method on the list.
Most programmers opt to use StringTokenizer in tokenizing a string than StreamTokenizer because the methods are much simpler than the latter.
String nextToken String delim This method returns the next token in this string tokenizer’s string. If the returnDelims flag is truethen the delimiter characters are also returned as tokens. Calculates the number of times that this tokenizer’s nextToken method can be called before it generates an exception. We also have the ability to change the delimiter anytime.
The StreamTokenizer class is in the java. If the flag is falsedelimiter characters serve to separate tokens.
Use is subject to license terms.
There are multiple constructors available for StringTokenizer, one of it accepts a delimiter apart from the input String. We can use a FileReader object or any other Reader object as tutorkal data source.
Some operations advance this current position past the characters processed. Note that if delim is nullthis constructor does not throw an exception. Returns the absolute value of a long value.
From the above code, we basically just create a new StringTokenizer object and make use of one of the class constructor to initialize the String to be tokenized. Stringtokenier class allows you to break a string into tokens.
Thank u for giving this information.
The nextToken method actually return stringtpkenizer current token and then point to the next token if there are still available on the buffer.
The nextToken method of StreamTokenizer is called repeatedly. An instance of StringTokenizer behaves in one of two ways, depending on whether it was created with the returnDelims flag having the value true or false: Constructs a string tokenizer stingtokenizer the specified string.
The program uses a StringReader object as the data source. Follow him on Stringtokenizefor befriend him on Facebook or Google Plus.

Hi mkyong, What if I like to split both space and comma at the same time.? A StringTokenizer breaks a string into tokens whereas a StreamTokenizer gives we access to the tokens in a character-based stream.
Each delimiter is returned as a string of length one.
This method calculates the number of times that this tokenizer’s nextToken method can be called before it generates an exception. Contact Info Singapore Email: If the flag is false, delimiter characters serve to separate tokens.
StringTokenizer (Java Platform SE 7 )
August 30, Viewed: I did this is in easiest mode for understanding everyone please try this who are going to learn java tokenizers try this……………. It is highly recommended to use the split method of String class or the java. StringTokenizer A StringTokenizer object breaks a string into tokens based on your definition of delimiters.
This method returns the same value as the nextToken method, except that its declared return value is Object rather than String. We define the sequence of characters that are considered tokens by defining delimiter characters. My question is how i can know tokenization like that in java? The current position is not advanced.
Excuis sir i have problem in my thesis. The StringTokenizer class is in the java. The tokenization method is much simpler than the one used by the StreamTokenizer class.
I am getting some exception in this programe… import java. Thanks, i have read of StringTonkenizer content but some how in ur site it is not completed, it is half on right side of page. The above example is pretty basic, first we have initialized a new StringTokenizer object which we already have discussed. NoSuchElementException – if there are no more tokens in this tokenizer’s string. The following code shows how to use the StringTokenizer and the split method of the String class.
The new delimiter set remains the default after this call. A StringTokenizer object internally maintains a current position within the string to be tokenized. An instance of StringTokenizer behaves in one of two ways, depending on whether it was created with the returnDelims flag having the value true or false: We can specify your own delimiters when we create a StringTokenizer as follows: If you have understand the code above, then you are good to go.
