Usando List em java

Bom dia Pessoal,

To fazendo uma conexão JDBC no Mysql para retornar uma List pra um componente na minha parte de view.
Porém não sei usar o List em java direito.
Tenho que implementar os métodos do List assim:

List<String> listaRetorno = new List<String>() {

                public int size() {
                    throw new UnsupportedOperationException("Not supported yet.");
                }

                public boolean isEmpty() {
                    throw new UnsupportedOperationException("Not supported yet.");
                }

                public boolean contains(Object o) {
                    throw new UnsupportedOperationException("Not supported yet.");
                }

                public Iterator<String> iterator() {
                    throw new UnsupportedOperationException("Not supported yet.");
                }

                public Object[] toArray() {
                    throw new UnsupportedOperationException("Not supported yet.");
                }

                public <T> T[] toArray(T[] a) {
                    throw new UnsupportedOperationException("Not supported yet.");
                }

                public boolean add(String e) {
                    throw new UnsupportedOperationException("Not supported yet.");
                }

                public boolean remove(Object o) {
                    throw new UnsupportedOperationException("Not supported yet.");
                }

                public boolean containsAll(Collection<?> c) {
                    throw new UnsupportedOperationException("Not supported yet.");
                }

                public boolean addAll(Collection<? extends String> c) {
                    throw new UnsupportedOperationException("Not supported yet.");
                }

                public boolean addAll(int index, Collection<? extends String> c) {
                    throw new UnsupportedOperationException("Not supported yet.");
                }

                public boolean removeAll(Collection<?> c) {
                    throw new UnsupportedOperationException("Not supported yet.");
                }

                public boolean retainAll(Collection<?> c) {
                    throw new UnsupportedOperationException("Not supported yet.");
                }

                public void clear() {
                    throw new UnsupportedOperationException("Not supported yet.");
                }

                public String get(int index) {
                    throw new UnsupportedOperationException("Not supported yet.");
                }

                public String set(int index, String element) {
                    throw new UnsupportedOperationException("Not supported yet.");
                }

                public void add(int index, String element) {
                    throw new UnsupportedOperationException("Not supported yet.");
                }

                public String remove(int index) {
                    throw new UnsupportedOperationException("Not supported yet.");
                }

                public int indexOf(Object o) {
                    throw new UnsupportedOperationException("Not supported yet.");
                }

                public int lastIndexOf(Object o) {
                    throw new UnsupportedOperationException("Not supported yet.");
                }

                public ListIterator<String> listIterator() {
                    throw new UnsupportedOperationException("Not supported yet.");
                }

                public ListIterator<String> listIterator(int index) {
                    throw new UnsupportedOperationException("Not supported yet.");
                }

                public List<String> subList(int fromIndex, int toIndex) {
                    throw new UnsupportedOperationException("Not supported yet.");
                }
            };

Desse jeito da o seguinte erro:java.lang.UnsupportedOperationException: Not supported yet.
E se não implementar os métodos da esse erro:java.lang.NullPointerException.

Então como posso fazer isso???
Ta retornando certo so dados do banco!
