StringTokenizer

Let us consider one example for splitting a complete string into different words.

import java.util.StringTokenizer;  public class StringTockenizer {             public static void main(String[] args) {         String str=””;          try{                    str = “This is for learning StringTokenizer”;               StringTokenizer token = new StringTokenizer(str);               System.out.println(“Token count is “+token.countTokens());               while (token.hasMoreTokens())               {                       str = token.nextToken();                     System.out.println(str);               }                }         catch(Exception e)         {               e.printStackTrace();         }  } }

Output

Token count is 5

 Important methods

1.      hasMoreTokens():
