java String...!

Question

I am currently using StringTokennizer class to split a String into different tokenas by defined delimiter

 public class App {  
        public static void main(String[] args) {  

            String str = "This is String , split by StringTokenizer, created by saral";  
            StringTokenizer st = new StringTokenizer(str);  


            System.out.println("---- Split by comma ',' ------");  
            StringTokenizer st2 = new StringTokenizer(str, ",");  

            while (st2.hasMoreElements()) {  
                System.out.println(st2.nextElement());  
            }  
        }  
    }

Please advise me more alternative ways to achieve this as jdk 5 support scanner and java .util, regex....!! please advise..!!

Please use a single period to end a sentence. – Skip Head Apr 06 '12 at 16:22 — Skip Head, Apr 06 '12 at 16:22

You could use java.lang.String.split() method:

String str = ...;
String[] tokens = str.split(",");

for (String s: tokens)
{
    System.out.println(s);
}

Can I use scanner also..to achieve the same thing..!! – dghtr Apr 06 '12 at 16:16
@SARAL `Scanner` is useful for reading a stream of characters, and `split()` for splitting it. They complement each other. – Óscar López Apr 06 '12 at 23:36

You can just use String.split.

String str = "This is String , split by StringTokenizer, created by saral";
String[] arr = str.split(",");

Now, arr will be an array containing each comma-separated part of str.

StringTokenizer is deprecated for all practical purposes, it's there only for backwards compatibility. Use the method split() instead, like this:

String[] splitted = str.split(",");

Now the returned String[] will contain the tokens.

I was looking for java regex or something new ,I want to avoid string split method and tokenizer some thing new from regex..!! – dghtr Apr 06 '12 at 16:20
@SARAL read the documentation of `split()` in the link, it receives a regular expression as a parameter! in this simple example `","` is a regex, but it can be as complex as you want – Óscar López Apr 06 '12 at 16:31
