### Question:
ConstraintReportId implements Serializable { @Override public int hashCode() { return Objects.hashCode(this.resourceId,this.failureId); } private  ConstraintReportId(); private  ConstraintReportId(ResourceId resourceId, String failureId); ResourceId resourceId(); String failureId(); @Override int hashCode(); @Override boolean equals(Object obj); @Override String toString(); static ConstraintReportId create(ResourceId resourceId, String failureId);  }### Answer:
@Test public void testHashCode() { ConstraintReportId id1 = constraintReportId("name", "failureId"); ConstraintReportId id2 = constraintReportId("name", "failureId"); assertThat(id1.hashCode(),equalTo(id2.hashCode())); }
