    ArrayList printout?

    hi. i am at the end of a long weekend of doing nothing but working on a programming assignment.

    i have an ArrayList and want to print out each element. each element is an int array. not sure how to print it out. the relevant code is below. but basically, i have used an iterator to create new arrays in another class. they are collected in my test class and printed out there. i just don't know how to convert it from hash code into something readable. a toString method ? i am sorry to have to ask this, i am just brain dead.

    while (iterator.OneRoll_hasNext()){
    new_pos = (iterator.OneRoll_next());
    oneResult.add(new_pos);
    }
    for (int i =0; i<oneResult.size(); i++){
    System.out.println(oneResult.get(i));
    }
    }


    thanks

    thanks anyway, but i think there is something wrong with those codes. tried them several different ways and they aren't working.

    a.iterator(); iter.hasNext() {

    that part of the first code is really strange


    and

    System.out.println((String)(iter.get(i)));

    that part of the second code doesn't work with a for loop with no "iter".

    i might just have to turn it in as is. i think it WORKS fine. and it is 1 AM and i just don't have another HOUR to figure this out.

    thanks
