以下例子將告訴你如何使用 java.util.StringTokenizer.hasMoreTokens()

package gitbook.net;

import java.util.*;

public class StringTokenizerDemo {
   public static void main(String[] args) {
      // creating string tokenizer
      StringTokenizer st = new StringTokenizer("Come to learn");
      
      // counting tokens
      System.out.println("Total tokens : " + st.countTokens()); 
      
      // checking tokens
      while (st.hasMoreTokens()){
         System.out.println("Next token : " + st.nextToken());    
      }
   }    
}

Let us compile and run the above program, this will produce the following result.

Total tokens : 3
Next token : Come
Next token : to
Next token : learn
