Stack Overflow error adding an object in ArrayList of []

I get stack overflow error when I try to load(). I am trying to read PhoneBookEntry objects from a txt file. The txt file has a name and number which make up the PhoneBookEntry object.

Can you please let me know what I'm doing wrong?

package HashSet;

        this(10);
    }

    public PhoneBook(int size) {
        capacity = size;
        buckets = new ArrayList[size];
        for (int i = 0; i < buckets.length; i++) {
            buckets[i] = new ArrayList<PhoneBookEntry>();
        }
    }

    public int getSize() {
        int tot = 0;
        for (ArrayList<PhoneBookEntry> x : buckets)
            tot += x.size();
        return tot;
    }

        if (contains(entry))
            return false;

        buckets[x % buckets.length].add(entry);
