A StringTokenizer class is a class present in the java. util package and it is used to break a String into tokens. In other words, we can split a sentence into its words and perform various operations like counting the number of tokens or breaking a sentence into tokens.
What is the purpose of StringTokenizer 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.
Is StringTokenizer deprecated?
StringTokenizer is a legacy class (i.e. there is a better replacement out there), but it’s not deprecated.
What is nextToken in Java?
The nextToken(String delim) method is used to return the next token in this string tokenizer’s string. First, the set of characters considered to be delimiters by this StringTokenizer object is changed to be the characters in the string delim. Then the next token in the string after the current position is returned.
What is Tokenizing a string?
String tokenization is a process where a string is broken into several parts. Each part is called a token. For example, if “I am going” is a string, the discrete parts—such as “I”, “am”, and “going”—are the tokens.
What is the difference between StringTokenizer and split?
A token is returned by taking a substring of the string that was used to create the StringTokenizer object.
Difference Between StringTokenizer and Split Method in Java.
|It just accepts a String by which it will split the string||It accepts regular expressions.|
|The delimiter is just a character long.||The delimiter is a regular expression.|
Which package contains StringTokenizer?
util package includes StringTokenizer tokenizes string into independent words – Core Java.
How many constructors are defined in StringTokenizer class?
There are 3 constructors defined in the StringTokenizer class.
How do you pass multiple delimiters in Java?
In order to break String into tokens, you need to create a StringTokenizer object and provide a delimiter for splitting strings into tokens. You can pass multiple delimiters e.g. you can break String into tokens by, and: at the same time. If you don’t provide any delimiter then by default it will use white-space.
What are string classes in Java?
The String class represents character strings. All string literals in Java programs, such as “abc” , are implemented as instances of this class. Strings are constant; their values cannot be changed after they are created. … Because String objects are immutable they can be shared.
What is the use of hasMoreTokens?
The hasMoreTokens() method is used to test if there are more tokens available from this tokenizer’s string.
Which of the following can break sentence into small tokens?
Correct Option :C. break sentence into small tokens using split() or StringTokenizer.
What is tokenization in NLTK?
NLTK contains a module called tokenize() which further classifies into two sub-categories: Word tokenize: We use the word_tokenize() method to split a sentence into tokens or words. Sentence tokenize: We use the sent_tokenize() method to split a document or paragraph into sentences.
What are tokens?
In general, a token is an object that represents something else, such as another object (either physical or virtual), or an abstract concept as, for example, a gift is sometimes referred to as a token of the giver’s esteem for the recipient. In computers, there are a number of types of tokens.
