Example:

In the example below, the java.util.StringTokenizer.countTokens() method is used to count the total number of tokens in the given string tokenizer.

import java.util.*;

public class MyClass {
  public static void main(String[] args) {
    //creating a string tokenizer.
    StringTokenizer st = new StringTokenizer("Alpha,Coding,Skills",",");
   
    //printing total numbers of tokens
    System.out.println("Token Count is: " + st.countTokens());

    //printing tokens of the string tokenizer.
    System.out.println("StringTokenizer contains: ");
    while(st.hasMoreElements()) 
      System.out.println(st.nextElement());  
  }
}

The output of the above code will be:

Token Count is: 3
StringTokenizer contains: 
Alpha
Coding
Skills
