The hasMoreTokens() method of StringTokenizer class checks whether there are any more tokens available with this StringTokenizer.
Syntax:
public boolean hasMoreTokens()
Parameters: The method does not take any parameters.
Return Value: The method returns boolean True if the availability of at least one more token is found in the string after the current position else false.
Below programs illustrate the working of hasMoreTokens() Method of StringTokenizer:
Example 1:
// Java code to illustrate hasMoreTokens() method  import java.util.*;  public class StringTokenizer_Demo {    public static void main(String args[])    {        // Creating a StringTokenizer        StringTokenizer str_arr            = new StringTokenizer(                "Lets practice at Lazyroar");          // Counting the tokens        System.out.println("The number of Tokens are: "                           + str_arr.countTokens());          // Checking for any tokens        System.out.println(str_arr.hasMoreTokens());          // Checking and displaying the Tokens        while (str_arr.hasMoreTokens()) {            System.out.println("The Next token: "                               + str_arr.nextToken());        }    }} |
Output:
The number of Tokens are: 4 true The Next token: Lets The Next token: practice The Next token: at The Next token: Lazyroar
Example 2:
// Java code to illustrate hasMoreTokens() method  import java.util.*;  public class StringTokenizer_Demo {    public static void main(String args[])    {        // Creating a StringTokenizer        StringTokenizer str_arr            = new StringTokenizer("");          // Counting the tokens        System.out.println("The number of Tokens are: "                           + str_arr.countTokens());          // Checking for any tokens        System.out.println(str_arr.hasMoreTokens());    }} |
Output:
The number of Tokens are: 0 false
