### Question:
DenialConstraintResult implements RankingResult { public boolean equals(Object obj) { if (this == obj) { return true; } if (obj == null) { return false; } if (getClass() != obj.getClass()) { return false; } DenialConstraintResult other = (DenialConstraintResult) obj; return this.result.equals(other.getResult()); } DenialConstraintResult();  DenialConstraintResult(DenialConstraint result); DenialConstraint getResult(); void setResult(DenialConstraint result); boolean equals(Object obj); @Override int hashCode();  }### Answer:
@Test public void testEquals() throws InputGenerationException, InputIterationException { DenialConstraint expectedResult = new DenialConstraint(); DenialConstraint expectedResult2 = new DenialConstraint(); DenialConstraintResult rankingResult1 = new DenialConstraintResult(expectedResult); DenialConstraintResult rankingResult2 = new DenialConstraintResult(expectedResult2); assertEquals(rankingResult1, rankingResult1); assertEquals(rankingResult1, rankingResult2); }
