### Question:
CellId implements Serializable { public int getZoomLevel() { return this.zoomLevel; } CellId(int zoomLevel, long id); static long getLevelId(int zoomlevel, long id); long getLevelId(); static CellId fromLevelId(long levelId); long getId(); @Override boolean equals(Object o); @Override int hashCode(); @Override String toString(); int getZoomLevel();  }### Answer:
@Test public void testGetzoomlevel() { CellId instance = new CellId(1,1L); int expResult = 1; int result = instance.getZoomLevel(); assertEquals(expResult, result); }
