### Question:
ReleaseTransactionSet { public Set<Entry> getEntries() { return new HashSet<>(entries); } ReleaseTransactionSet(Set<Entry> entries); Set<Entry> getEntries(); void add(UldTransaction transaction, Long blockNumber); Set<UldTransaction> sliceWithConfirmations(Long currentBlockNumber, Integer minimumConfirmations, Optional<Integer> maximumSliceSize);  }### Answer:
@Test public void entriesCopy() { Assert.assertNotSame(setEntries, set.getEntries()); Assert.assertEquals(setEntries, set.getEntries()); }
