java - Print ArrayList

Question

I have an ArrayList that contains Address objects.

How do I print the values of this ArrayList, meaning I am printing out the contents of the Array, in this case numbers.

I can only get it to print out the actual memory address of the array with this code:

for(int i = 0; i < houseAddress.size(); i++) {   
    System.out.print(houseAddress.get(i));
}  

Answer 1

list.toString() is good enough.

The interface List does not define a contract for toString(), but the AbstractCollection base class provides a useful implementation that ArrayList inherits.
