Separator-based string separation

I am trying to break up a very simple set of lines that go into forms

0|0
10|15
30|55

etc. Essentially numbers separated by pipes.

When I use java string split function with .split ("|"). I get some unpredictable results. a space in the first slot, sometimes the number itself is not where I thought it should be.

Can someone help and give me advice, how can I use reg exp to store ONLY integers?

I was asked to give a code trying to make the actual split. So let me do this to further clarify my problem :)

String temp = "0|0";
String splitString = temp.split("|");

results

\n
0
| 
0

I'm trying to get

0
0

only. Thanks forever for any help in advance :)

        StringBuffer token = new StringBuffer();
        Vector tokens = new Vector();
        char[] chars = stringToSplit.toCharArray();
        for (int i=0; i  0) {
               tokens.addElement(token.toString());
               token.setLength(0);
               i++;
         }
         } else {

         if (token.length() > 0) {
             tokens.addElement(token.toString());
         }
         // convert the vector into an array
         String[] preparedArray = new String[tokens.size()];
         for (int i=0; i < preparedArray.length; i++) {
             preparedArray[i] = (String)tokens.elementAt(i);
         }
         return preparedArray;
    }

Above the code fragment is a call to the StringSplitToArray method, where the string is converted into a string array in the method, dividing the string depending on the specified separator or passed to the method. The delimiter can be a comma delimiter (,) or a double code (").
