### Question:
ShardNameHelper { public String getFullShardPrunId(Long shardId, UUID chainId) { String result = String.format(SHARD_PRUN_ID_PATTERN, shardId, chainId.toString()); return result; } ShardNameHelper(); String getShardNameByShardId(Long shardId, UUID chainId); String getFullShardId(Long shardId, UUID chainId); String getFullShardPrunId(Long shardId, UUID chainId); String getCoreShardArchiveNameByShardId(Long shardId, UUID chainId); String getPrunableShardArchiveNameByShardId(Long shardId, UUID chainId);  }### Answer:
@Test void getFullPrunableShardId() { ShardNameHelper shardNameHelper = new ShardNameHelper(); String result = shardNameHelper.getFullShardPrunId(001L, chainId); assertEquals("shardprun::1;chain::b5d7b697-f359-4ce5-a619-fa34b6fb01a5", result); result = shardNameHelper.getFullShardPrunId(2001L, chainId); assertEquals("shardprun::2001;chain::b5d7b697-f359-4ce5-a619-fa34b6fb01a5", result); }
