### Question:
GenericServiceTask extends BaseTask implements DataIOModel { @Override public int hashCode() { return HashUtil.combineHashCodes(super.hashCode(), executionSet.hashCode()); } GenericServiceTask();  GenericServiceTask(final @MapsTo("general") TaskGeneralSet general,
                              final @MapsTo("executionSet") GenericServiceTaskExecutionSet executionSet,
                              final @MapsTo("backgroundSet") BackgroundSet backgroundSet,
                              final @MapsTo("fontSet") FontSet fontSet,
                              final @MapsTo("dimensionsSet") RectangleDimensionsSet dimensionsSet,
                              final @MapsTo("simulationSet") SimulationSet simulationSet,
                              final @MapsTo("taskType") TaskType taskType); GenericServiceTaskExecutionSet getExecutionSet(); void setExecutionSet(final GenericServiceTaskExecutionSet executionSet); @Override boolean hasInputVars(); @Override boolean isSingleInputVar(); @Override boolean hasOutputVars(); @Override boolean isSingleOutputVar(); @Override int hashCode(); @Override boolean equals(Object o);  }### Answer:
@Test public void testHashCode() { GenericServiceTask a = new GenericServiceTask(); GenericServiceTask b = new GenericServiceTask(); assertEquals(a.hashCode(), b.hashCode()); }
