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
