### Question:
ContainerAdminData { @Override public int hashCode() { return Objects.hashCode(this.gadgetAdminMap); } ContainerAdminData();  ContainerAdminData(Map<String, GadgetAdminData> gadgetAdminMap); void addGadgetAdminData(String gadgetUrl, GadgetAdminData toAdd); GadgetAdminData removeGadgetAdminData(String gadgetUrl); GadgetAdminData getGadgetAdminData(String gadgetUrl); Map<String, GadgetAdminData> getGadgetAdminMap(); void clearGadgetAdminData(); boolean hasGadgetAdminData(String gadgetUrl); @Override boolean equals(Object obj); @Override int hashCode();  }### Answer:
@Test public void testHashCode() { assertEquals(Objects.hashCode(this.gadgetMap), validData.hashCode()); assertEquals(Objects.hashCode(Maps.newHashMap()), nullData.hashCode()); assertEquals(Objects.hashCode(Maps.newHashMap()), emptyData.hashCode()); assertEquals(Objects.hashCode(Maps.newHashMap()), defaultData.hashCode()); assertEquals(nullData.hashCode(), emptyData.hashCode()); assertFalse(validData.hashCode() == defaultData.hashCode()); }
