Answer 1

here is a Utility method to split an array and put your custom delimiter, using

String.replace(String,String)
Arrays.toString(Object[])

here it is :

public static String toString(String delimiter, Object[]array){
    String s = "";

    // split array
    if (array != null && array.length > 0) {
        s = Arrays.toString(array).replace("[", "").replace("]", "");
    }

    // place delimiter (notice the space in ", ")
    if(delimiter != null){
        s = s.replace(", ", delimiter);
    }

    return s;
}

change the second argument type to suite your array type
