    Default Can i just use toString?

    Hi, example you can split a String into a String[] with
    Java Code:
    String[] arrString = strString.split(strDelimiter);
    But how can i join this array back into a string without looping though every element, isn't there an inverse function of split, which is usually called join? Can i just use toString?

    In which case how do i do a delimiter between the joined strings.

    Thanks.

    Default

    Only way I know of doing it is to use a StringBuilder.
    Loop through each element and append it to the StringBuilder with the delimiter.
