oder die normale Trim Methode abgeändert:

Code:
    /** Links trim */
    public static String trimLeft(final String s){
        return trim(s, true);
    }
    
    /** Rechts trim */
    public static String trimRight(final String s){
        return trim(s, false);
    }
    
    private static String trim(final String s, boolean left){
        char[] value = s.toCharArray();
        int len = value.length;
        int st = 0;
        char[] val = value;
        if (left){
            while ((st < len) && (val[st] <= ' ')) {
                st++;
            }
        }else{
            while ((st < len) && (val[len - 1] <= ' ')) {
                len--;
            }
        }
        return ((st > 0) || (len < value.length)) ? s.substring(st, len) : s;
    }
