String Split() method and pipes

I'm lost for trying to explain this:

public class wtf
  public static void main(String[] args)
    String str = "abcdef";
    String[] ary = str.split("|");
    for(int i = 0; i < ary.length; i++)
/*The output of this program is:


Basicly I have a Vector of pipe delimited strings that I need to turn into a Vector of String arrays (broken at the pipes).

no worries :)
The split may not work if the excape is used for delimiters. Thus the split doesn't work generacally for any delimiter. On can try out this mthod.

public static String[] split(String inputString, String splitter)
        List outputList = new ArrayList();
        if(inputString == null || splitter == null){
            String[] output =  (String[])outputList.toArray();
            return output;
        //if the value doesn't end with the delimiter then added is as we need to get the last value
        int idx = inputString.indexOf(splitter);
            inputString = inputString+splitter;
        while(idx != -1){
            String value = inputString.substring(0, idx);
            int next = idx+splitter.length();
            inputString = inputString.substring(next);
            idx = inputString.indexOf(splitter);

        Object[] objectArray = new String[outputList.size()];
        String[] output = (String[]) objectArray;

        return output;
