### Question:
AttributeType extends StandardEntity<AttributeType> { @Override public boolean equals(Object object) { if (!(object instanceof AttributeType)) { return false; } AttributeType other = (AttributeType) object; if (this.attributeType == null && other.attributeType == null) { return super.equals(object); } if ((this.attributeType == null && other.attributeType != null) || (this.attributeType != null && !this.attributeType.equals(other.attributeType))) { return false; } return true; } @SuppressWarnings({"squid:S2637", "squid:S1186"})  AttributeType(); void updateNullFlags(); @Override void updateFields(StandardEntity entity); ValidationResult customValidation(); void addOptionalComponentType(String componentType); void addRequiredComponentType(String componentType); @Override int hashCode(); @Override boolean equals(Object object); String getAttributeType(); void setAttributeType(String attributeType); String getDescription(); void setDescription(String description); Boolean getVisibleFlg(); void setVisibleFlg(Boolean visibleFlg); Boolean getRequiredFlg(); void setRequiredFlg(Boolean requiredFlg); Boolean getArchitectureFlg(); void setArchitectureFlg(Boolean architectureFlg); Boolean getImportantFlg(); void setImportantFlg(Boolean importantFlg); Boolean getAllowMultipleFlg(); void setAllowMultipleFlg(Boolean allowMultipleFlg); Boolean getHideOnSubmission(); void setHideOnSubmission(Boolean hideOnSubmission); String getDefaultAttributeCode(); void setDefaultAttributeCode(String defaultAttributeCode); String getDetailedDescription(); void setDetailedDescription(String detailedDescription); List<ComponentTypeRestriction> getRequiredRestrictions(); void setRequiredRestrictions(List<ComponentTypeRestriction> requiredRestrictions); List<ComponentTypeRestriction> getAssociatedComponentTypes(); void setAssociatedComponentTypes(List<ComponentTypeRestriction> associatedComponentTypes); Boolean getAllowUserGeneratedCodes(); void setAllowUserGeneratedCodes(Boolean allowUserGeneratedCodes); String getAttributeValueType(); void setAttributeValueType(String attributeValueType); List<ComponentTypeRestriction> getOptionalRestrictions(); void setOptionalRestrictions(List<ComponentTypeRestriction> optionalRestrictions); static final String FIELD_ATTRIBUTE_TYPE; static final String TYPE; static final String DI2ELEVEL; }### Answer:
@Test public void testEquals() { System.out.println("equals"); Object object = null; AttributeType instance = new AttributeType(); boolean expResult = false; boolean result = instance.equals(object); assertEquals(expResult, result); }
