Problem with delim in StringTokenizer

I am having a problem with StringTokenizer, i would like to delim on a string "->" the problem i am having is the strings i am tokenizing sometimes have a '-' or a '>' in them, and when ever it finds either it counts it as a token, is there a way to force it to use a string to delim or am i going to have to write my own? I have written an example below, any help would be much appreciated.


Code:

Code:

---

import java.util.*;
class testtoken{
        public static void main (String [] args){
                int i;
                String [] testtoken = new String[4];
                testtoken[0] = "Test->Token->Test";
                testtoken[1] = "Test->To-ken->Test";
                testtoken[2] = "Test->To>ken->Test";
                testtoken[3] = "Test->To->ken->Test";
                                               
                for(i = 0; i < testtoken.length; i++){
                        System.out.println("String: " + testtoken[i]);
                        StringTokenizer st = new StringTokenizer(testtoken[i],"->");
                       
                        while(st.hasMoreTokens()){
                                System.out.println("\t" + st.nextToken());
                        }
                }
        }
}

---

Output:

Code:

---

String: Test->Token->Test
        Test
        Token
        Test
String: Test->To-ken->Test
        Test
        To
        ken
        Test
String: Test->To>ken->Test
        Test
        To
        ken
        Test
String: Test->To->ken->Test
        Test
        To
        ken
        Test

---

Desired Output:

Code:

---

String: Test->Token->Test
        Test
        Token
        Test
String: Test->To-ken->Test
        Test
        Token
        Test
String: Test->To>ken->Test
        Test
        Token
        Test
String: Test->To->ken->Test
        Test
        To
        ken
        Test

Dealing with different delimiters with StringTokenizer is a bit fiddly. StringTokenizer has largely been superseded by the String.split() method, and the regular expressions API in general. Try the following:

Code:

---

String[] toks = str.split("\\b(-|>|->)\\b");

---

In the pattern you pass into split():
\\b means a "word boundary"
| means an "alternative"

To find out more, read about Java regular expressions (link is to one of my tutorials; see also the documentation of the Pattern class).

Thanks Neil, it is now working perfectly!

Code:

---

import java.util.*;
class token{
        public static void main (String [] args){
                int i;
                String [] testtoken = new String[4];
                testtoken[0] = "Test->Token->Test";
                testtoken[1] = "Test->To-ken->Test";
                testtoken[2] = "Test->To>ken->Test";
                testtoken[3] = "Test->To->ken->Test";
                                               
                for(i = 0; i < testtoken.length; i++){
                        System.out.println("String: " + testtoken[i]);
                                       
                        String[] toks = testtoken[i].split("\\b(->)\\b");

                        for(int t = 0; t < toks.length; t++){
                                System.out.println("\t" + toks[t]);
                               
                        }
                }
        }
}

Output:

Code:

---

String: Test->Token->Test
        Test
        Token
        Test
String: Test->To-ken->Test
        Test
        To-ken
        Test
String: Test->To>ken->Test
        Test
        To>ken
        Test
String: Test->To->ken->Test
        Test
        To
        ken
        Test
