### Question:
ShardType1UUIDGeneratorStrategy implements UUIDGeneratorStrategy { @Override public String generateId() { StringBuilder builder = new StringBuilder(); char c1 = (char) (r.nextInt(26) + 'a'); char c2 = (char) (r.nextInt(26) + 'a'); builder.append(new DateTime().getYear()); builder.append(c1); builder.append(c2); builder.append("-"); builder.append(generator.generate().toString()); String uuid = builder.toString(); return uuid; }  @Override String generateId(); @Override String generateId(NaturalKeyDescriptor naturalKeyDescriptor);  }### Answer:
@Test public void testShardType1UUIDGenerator() { ShardType1UUIDGeneratorStrategy uuidGen = new ShardType1UUIDGeneratorStrategy(); String uuid = uuidGen.generateId(); assertNotNull(uuid); assertEquals('1', uuid.charAt(22)); assertEquals(43, uuid.length()); }
