Answer 1

The simple way is to add a method to the Contact like this:

public Object[] toObjectArray() {
    return new Object[] { getName(), getAddress, /* ... */ };
}

and use it like this:

ArrayList contacts = /* ... */
Object[][] table = new Object[contacts.size()][];
for (int i = 0; i < contacts.size(); i++) {
    table[i] = contacts.get(i).toObjectArray();
}
