What is StringTokenizer.hasMoreTokens() in Java?

The hasMoreTokens method of the StringTokenizer class is an instance method that checks if there are any more tokens in the tokenizer’s string. If the result of this procedure is true, then there are more tokens to be retrieved.

The next token can be retrieved via the nextToken() method, which makes the pointer move forward in the list of tokens after the tokenization of the string.

The StringTokenizer class is defined in the java.util package.

To import the StringTokenizer class, use the import statement below:

import java.util.StringTokenizer;

Syntax

public boolean hasMoreTokens()

Parameters

This method has no parameters.

Return value

hasMoreTokens() returns true if there is at least one token following the current place in the string. Otherwise, the method returns false.

Code

In the code below:

  • We create an object of the StringTokenizer class and pass the s string and the - delimiter.

  • We first use the hasMoreTokens() method to check if any tokens are present in stringTokenizer. Since stringTokenizer has tokens, the method returns true.

  • We then loop through all the available tokens using the hasMoreTokens() and nextToken() methods.

  • After all the tokens are retrieved, the hasMoreTokens() method returns false, as there are no more tokens available.

import java.util.StringTokenizer;
public class Main{
    public static void main(String[] args){
        String s = "hello-hi-educative";
        StringTokenizer stringTokenizer = new StringTokenizer(s, "-");
        System.out.println(stringTokenizer.hasMoreTokens());
        while(stringTokenizer.hasMoreTokens()){
            System.out.println(stringTokenizer.nextToken());
        }
        System.out.println("End of all tokens");
        System.out.println(stringTokenizer.hasMoreTokens());
    }
}
