### Question:
OSMWay extends OSMEntity implements Comparable<OSMWay>, Serializable { @Override public int compareTo(OSMWay o) { int c = Long.compare(id, o.id); if (c == 0) { c = Integer.compare(Math.abs(version), Math.abs(o.version)); } if (c == 0) { c = Long.compare(timestamp.getRawUnixTimestamp(), o.timestamp.getRawUnixTimestamp()); } return c; } OSMWay(final long id, final int version, final OSHDBTimestamp timestamp, final long changeset,
      final int userId, final int[] tags, final OSMMember[] refs); @Override OSMType getType(); OSMMember[] getRefs(); Stream<OSMNode> getRefEntities(OSHDBTimestamp timestamp); @Override String toString(); @Override int compareTo(OSMWay o);  }### Answer:
@Test public void testCompareTo() { OSMMember part = new OSMMember(1L, OSMType.NODE, 1); OSMWay o = new OSMWay(1L, 1, new OSHDBTimestamp(1L), 1L, 1, new int[] {}, new OSMMember[] {part}); OSMWay instance = new OSMWay(1L, 1, new OSHDBTimestamp(1L), 1L, 1, new int[] {}, new OSMMember[] {part}); assertTrue(instance.compareTo(o) == 0); part = new OSMMember(1L, OSMType.NODE, 1); o = new OSMWay(1L, 3, new OSHDBTimestamp(1L), 1L, 1, new int[] {}, new OSMMember[] {part}); instance = new OSMWay(1L, 1, new OSHDBTimestamp(1L), 1L, 1, new int[] {}, new OSMMember[] {part}); assertTrue(instance.compareTo(o) < 0); part = new OSMMember(1L, OSMType.NODE, 1); o = new OSMWay(1L, 1, new OSHDBTimestamp(1L), 1L, 1, new int[] {}, new OSMMember[] {part}); instance = new OSMWay(1L, 3, new OSHDBTimestamp(1L), 1L, 1, new int[] {}, new OSMMember[] {part}); assertTrue(instance.compareTo(o) > 0); }
