### Question:
IpOverEthernetAddressData { public void setIpAddresses(List<IpAddresses> ipAddresses) { this.ipAddresses = ipAddresses; }  String getMacAddress(); void setMacAddress(String macAddress); List<IpAddresses> getIpAddresses(); void setIpAddresses(List<IpAddresses> ipAddresses);  }### Answer:
@Test public void setIpAddresses() { ipOverEthernetAddressData.setIpAddresses(new List<IpAddresses>() { @Override public int size() { return 0; } @Override public boolean isEmpty() { return false; } @Override public boolean contains(Object o) { return false; } @Override public Iterator<IpAddresses> iterator() { return null; } @Override public Object[] toArray() { return new Object[0]; } @Override public <T> T[] toArray(T[] a) { return null; } @Override public boolean add(IpAddresses ipAddresses) { return false; } @Override public boolean remove(Object o) { return false; } @Override public boolean containsAll(Collection<?> c) { return false; } @Override public boolean addAll(Collection<? extends IpAddresses> c) { return false; } @Override public boolean addAll(int index, Collection<? extends IpAddresses> c) { return false; } @Override public boolean removeAll(Collection<?> c) { return false; } @Override public boolean retainAll(Collection<?> c) { return false; } @Override public void clear() { } @Override public IpAddresses get(int index) { return null; } @Override public IpAddresses set(int index, IpAddresses element) { return null; } @Override public void add(int index, IpAddresses element) { } @Override public IpAddresses remove(int index) { return null; } @Override public int indexOf(Object o) { return 0; } @Override public int lastIndexOf(Object o) { return 0; } @Override public ListIterator<IpAddresses> listIterator() { return null; } @Override public ListIterator<IpAddresses> listIterator(int index) { return null; } @Override public List<IpAddresses> subList(int fromIndex, int toIndex) { return null; } }); }
