The land vehicle and the water vehicle are overlapping sub-The land vehicle and the water vehicle are overlapping sub-classes of the superclass vehicle. The overlapping sub-class is classes of the superclass vehicle. The overlapping sub-class is indicated by the solid triangle. They are overlapping sub-indicated by the solid triangle. They are overlapping sub-classes due to the fact that some vehicles can travel both on classes due to the fact that some vehicles can travel both on land and on water. Amphibious vehicle is the join class of land land and on water. Amphibious vehicle is the join class of land and water vehicles as it can travel both on land and on water. It and water vehicles as it can travel both on land and on water. It iherits some features from both the land vehicle and water iherits some features from both the land vehicle and water vehicle classes. The hollow triangle indicates disjoint sub-vehicle classes. The hollow triangle indicates disjoint sub-classes. For example, car and amphibious vehicle are disjoint classes. For example, car and amphibious vehicle are disjoint sub-classes.sub-classes.
