### Question:
ReflectionHelper { public static <T extends Collection<?>> T newCollectionInstance(final Class<T> clazz) { try { return clazz.newInstance(); } catch (InstantiationException | IllegalAccessException e) { throw new HibersapException(MSG_CAN_NOT_CREATE_INSTANCE + clazz.getName(), e); } } private  ReflectionHelper(); static Class<?> getClassForName(final String className); static Class<?> getArrayType(final Class<?> type); static Field getDeclaredField(final Object bean, final String fieldName); static Object getFieldValue(final Object bean, final String fieldName); static Class<?> getGenericType(final Field field); static T newCollectionInstance(final Class<T> clazz); static T newInstance(final Class<T> clazz); static T newInstance(final String fullyQualifiedClassName, final Class<T> superType); static List<T> createInstances(final List<String> fullyQualifiedClassNames, final Class<T> superType); static void setFieldValue(final Object bean, final String fieldName, final Object value); static Set<Field> getDeclaredFieldsWithAnnotationRecursively(final Class<?> clazz,
                                                                        final Class<? extends Annotation> annotationClass); static T[] newArrayFromCollection(final Collection<?> collection, final Class<T> elementType);  }### Answer:
@Test(expected = HibersapException.class) public void newCollectionInstanceThrowsExceptionForInterface() { ReflectionHelper.newCollectionInstance(List.class); }
