The StreamTokenizer class takes an input stream and parses it into "tokens", allowing the tokens to be read one at a time. 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. The StreamTokenizer class takes an input stream and parses it into "tokens", allowing the tokens to be read one at a time. The parsing process is controlled by a table and a number of flags that can be set to various states.

The Java documentation doesn't seem to mention anything about deprecation for StringTokenizer, yet I keep hearing about how it was deprecated long ago.Was it deprecated because it had bugs/errors, or is String.split() simply better to use overall?. I have some code that uses StringTokenizer and I am wondering if I should seriously be concerned about refactoring it to use String.split(), or

The StreamTokenizer class takes an input stream and parses it into "tokens", allowing the tokens to be read one at a time. The parsing process is controlled by a 17 Oct 2019 In this tutorial, we'll show how to parse a stream of characters into tokens using the Java StreamTokenizer class.

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.

The stream tokenizer can recognize identifiers, … Java Source Code here: http://ramj2ee.blogspot.com/2016/10/java-tutorial-java-io-java_94.html Click the below link to download the code: https://drive.google The Java StreamTokenizer is capable of recognizing identifiers, numbers, quoted strings, and various comment styles. You can also specify what characters are to be interpreted as white space, comment begin, end etc.

See this StreamTokenizer code example. Watch the American spelling. Using StreamTokenizer on an InputStream is now deprecated. Creates a stream tokenizer that parses the specified input stream.

Java has no built-in methods for reading data of the form: 123 456,-4. You have to roll your own method. Use java.io.StreamTokenizer or java.util.StringTokenizer, perhaps in combination with readLine to get your data into strings. StreamTokenizer has bells and whistles to deal with parsing source code, including white space, comments and numbers. In Java, you can easily use one of the sets from the collections library. I suggest a HashSet. – dcow Apr 1 '13 at 19:30 Ok once you compare the words, do you add the non-duplicates to another array and print that?
