Streamtokenizer vs stringtokenizer

Jan 17, 2001

These tokens will be read one at a time. StreamTokenizer can tokenize input stream on the basis of identifiers, numbers, quoted strings etc. To use StreamTokenizer we need to understand some static fields of it. I think the biggest difference is: with a StringTokenizer, the delimiter is just one character long.

Is this by design? 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. Lớp java.util.StringTokenizer cho phép bạn chia một chuỗi thành các token. Đây là cách đơn giản để chia chuỗi.

The java.io.StreamTokenizer.pushBack() method causes the next call to the nextToken method of this tokenizer to return the current value in the ttype field, and not to modify the value in the nval or sval field. Declaration. Following is the declaration for java.io.StreamTokenizer.pushBack() method. public void pushBack() Parameters. NA. Return

The StringTokenizer methods do not distinguish among identifiers, numbers, and quoted strings, nor do they recognize and skip comme

Using a StringTokenizer Most programmers use the String.split(String) method to convert a String to a String array specifying a delimiter. However, I feel it's unsafe to rely on the split() method in some cases, because it doesn't always work properly. The structure of the class StreamTokenizer is given as : pubic class java.io.StreamTokenizer extends java.lang.Object{ //member elements public double nval;//If the current token is a number, this field is used.

When you use StreamTokenizer, it's nextToken method returns an int which specifies the kind of token that has been identified. That value is one of the constants defined by the class: TT_EOF -- end of stream TT_EOL -- end of line The java.util.StringTokenizer class allows you to break a string into tokens. It is simple way to break string. It doesn't provide the facility to differentiate numbers, quoted strings, identifiers etc.

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 comme The Java StreamTokenizer class (java.io.StreamTokenizer) can tokenize the characters read from a Reader into tokens. For instance, in the string "Mary had a little lamb" each word is a separate token. StringTokenizer is a legacy class that is retained for compatibility reasons although its use is discouraged in new code.

Lớp java.util.StringTokenizer cho phép bạn chia một chuỗi thành các token. Đây là cách đơn giản để chia chuỗi. Lớp này không cung cấp phương tiện để phân biệt các số, các chuỗi đã được trích dẫn, các định danh indentifier, … giống như lớp StreamTokenizer. Using a StringTokenizer Most programmers use the String.split(String) method to convert a String to a String array specifying a delimiter. However, I feel it's unsafe to rely on the split() method in some cases, because it doesn't always work properly. StreamTokenizer should work fine for this; probably better than StringTokenizer (where you'd have to assemble the string before even beginning the parsing).

StringTokenizer example id created employee id firstname employeeType id lastname location Split example (id created employee(id firstname employeeType(id) lastname) location) There was a discussion on String.split() vs. StringTokenizer at Scanner vs. StringTokenizer vs. String.Split but it doesn't explain the parentheses. Is this by design?

When you use a StringTokenizer, it returns Strings that are the sequences of non-delimiter characters that it encounters. When you use StreamTokenizer, it's nextToken method returns an int which specifies the kind of token that has been identified. That value is one of the constants defined by the class: TT_EOF -- end of stream TT_EOL -- end of line

Constructors of StringTokenizer … I work on a large scale data set and as of that I am interested in the most efficient way to split a String.. Well I found that Scanner vs.

StreamTokenizer has bells and whistles to deal with parsing source code, including white space, comments and numbers. StringTokenizer just splits the text up based on delimiter characters. Then use the conversion methods in the conversion table to convert to integers etc.

Hello All, Till date Splitting a string in tokens is a more complex topic than String.Split() wants to make us believe. There are at least three common policies according to which a string might be interpreted and spli Like the StreamTokenizer, you can tell the StringTokenizer to break up the input in any way that you want, but with StringTokenizer you do this by passing a second argument to the constructor, which is a String of the delimiters you wish to use.
