### Question:
ServerAdminData { @Override public int hashCode() { return Objects.hashCode(this.containerAdminDataMap); } @Inject  ServerAdminData();  ServerAdminData(@Nullable Map<String, ContainerAdminData> containerAdminMap); ContainerAdminData getContainerAdminData(String container); void removeContainerAdminData(String container); void addContainerAdminData(String container, ContainerAdminData toAdd); Map<String, ContainerAdminData> getContainerAdminDataMap(); void clearContainerAdminData(); boolean hasContainerAdminData(String container); @Override boolean equals(Object obj); @Override int hashCode();  }### Answer:
@Test public void testHashCode() { assertEquals(Objects.hashCode(this.containerMap), 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()); }
