### Question:
RedisSequenceCounter implements SequenceCounter { @Override public long incrementAndGet() { Long increment = valueOperations.increment(counterKey, 1); if (increment != null) { return increment; } return 0L; } RedisSequenceCounter(String counterKey); @Override void set(long value); @Override Long get(); @Override long incrementAndGet(); @Override long increBy(long delta);  }### Answer:
@Test public void incrementAndGet() { long data = redisSequenceCounter.incrementAndGet(); Long data2 = redisSequenceCounter.get(); }
