What is the use of StringTokenizer?
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.
What is StringTokenizer class in Java?
StringTokenizer class allows an application to break a string into tokens. This class is a legacy class that is retained for compatibility reasons although its use is discouraged in new code. Its methods do not distinguish among identifiers, numbers, and quoted strings.
How does StringTokenizer work in Java?

What is a string token?
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. Java provides ready classes and methods to implement the tokenization process.

- Using String. split() Method.
- Using StringTokenizer Class.
What is difference between string and StringTokenizer?
StringTokenizer(String str)…Difference Between StringTokenizer and Split Method in Java.
| StringTokenizer | Split() |
|---|---|
| It is comparatively less robust & syntactically fussy. | It is more robust & has an easy syntax. |
| 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. |
What are various methods used in StringTokenizer class?
StringTokenizer Methods
- public boolean hasMoreTokens()
- public String nextToken()
- public int countTokens()
- public Object nextElement()
- public boolean hasMoreElements()
How do you use tokenization in Java?
To use String Tokenizer class we have to specify an input string and a string that contains delimiters. Delimiters are the characters that separate tokens. Each character in the delimiter string is considered a valid delimiter. Default delimiters are whitespaces, new line, space, and tab.
What are the various methods used in StringTokenizer class?
What is the purpose of StringTokenizer class write any two functions name of StringTokenizer class?
StringTokenizer class in Java is used to break a string into tokens. A StringTokenizer object internally maintains a current position within the string to be tokenized. Some operations advance this current position past the characters processed.
What is StringBuilder and StringTokenizer class?
StringBuffer serves same purpose as StringBuilder except that StringBuffer is thread-safe. StringTokenizer is used for splitting the string into tokens based on some delimiters.
Which of the following packages need to be important to use the StringTokenizer class?
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 are the methods used by StringTokenizer in Java?
Methods of StringTokenizer class are as follows:
- hasMoreToken.
- nextToken.
- countTokens.
- nextElement.
- hasMoreElements.
What is string split in Java?
The string split() method breaks a given string around matches of the given regular expression. After splitting against the given regular expression, this method returns a String array. Example: Input String: 016-78967 Regular Expression: – Output : {“016”, “78967”}
How does split work?
split() The split() method divides a String into an ordered list of substrings, puts these substrings into an array, and returns the array. The division is done by searching for a pattern; where the pattern is provided as the first parameter in the method’s call.
