### Question:
IpAddresses { public void setFixedAddresses(List<String> fixedAddresses) { this.fixedAddresses = fixedAddresses; }  String getType(); void setType(String type); List<String> getFixedAddresses(); void setFixedAddresses(List<String> fixedAddresses); int getNumDynamicAddresses(); void setNumDynamicAddresses(int numDynamicAddresses); AddressRange getAddressRange(); void setAddressRange(AddressRange addressRange); String getSubnetId(); void setSubnetId(String subnetId);  }### Answer:
@Test public void setFixedAddresses() { ipAddresses.setFixedAddresses(new List<String>() { @Override public int size() { return 0; } @Override public boolean isEmpty() { return false; } @Override public boolean contains(Object o) { return false; } @Override public Iterator<String> iterator() { return null; } @Override public Object[] toArray() { return new Object[0]; } @Override public <T> T[] toArray(T[] a) { return null; } @Override public boolean add(String s) { return false; } @Override public boolean remove(Object o) { return false; } @Override public boolean containsAll(Collection<?> c) { return false; } @Override public boolean addAll(Collection<? extends String> c) { return false; } @Override public boolean addAll(int index, Collection<? extends String> 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 String get(int index) { return null; } @Override public String set(int index, String element) { return null; } @Override public void add(int index, String element) { } @Override public String remove(int index) { return null; } @Override public int indexOf(Object o) { return 0; } @Override public int lastIndexOf(Object o) { return 0; } @Override public ListIterator<String> listIterator() { return null; } @Override public ListIterator<String> listIterator(int index) { return null; } @Override public List<String> subList(int fromIndex, int toIndex) { return null; } }); }
