### Question:
ClassType extends ComplexType implements Navigable { @Override public boolean isAbstract() { return isAbstract; } ClassType(final AssociationEnd lhs, final AssociationEnd rhs); private  ClassType(final boolean isClassType, final Identifier id, final String name, final boolean isAbstract,
            final List<Attribute> attributes, final AssociationEnd lhs, final AssociationEnd rhs,
            final List<TaggedValue> taggedValues);  ClassType(final Identifier id, final String name, final AssociationEnd lhs, final AssociationEnd rhs,
            final List<TaggedValue> taggedValues);  ClassType(final Identifier id, final String name, final boolean isAbstract,
            final List<Attribute> attributes, final AssociationEnd lhs, final AssociationEnd rhs,
            final List<TaggedValue> taggedValues);  ClassType(final Identifier id, final String name, final boolean isAbstract,
            final List<Attribute> attributes, final List<TaggedValue> taggedValues);  ClassType(final String name, final AssociationEnd lhs, final AssociationEnd rhs);  ClassType(final String name, final AssociationEnd lhs, final AssociationEnd rhs,
            final List<TaggedValue> taggedValues); void setAssociatedDatedCollectionStore(List<String> associatedDatedCollectionStore); Attribute getBeginDateAttribute(); Attribute getEndDateAttribute(); List<String> getAssociatedDatedCollectionStore(); @Override void accept(final Visitor visitor); @Override List<Attribute> getAttributes(); @Override AssociationEnd getLHS(); @Override AssociationEnd getRHS(); @Override boolean isAbstract(); @Override boolean isAssociation(); @Override boolean isClassType(); @Override boolean isDataType(); @Override boolean isEnumType(); @Override String toString();  }### Answer:
@Test public void testIsAbstract() { assertEquals(false, classType.isAbstract()); }
