| Description |
Suppose we have a class Point and we want to extend it to produce class Point3D. The class Point has two data members, x and y that represent the point's integer coordinates in the two-dimensional space. A Point3D has three data members, x, y, and z that represent the point's integer coordinates in the three-dimensional space. Write the class declarations, the constructors, and the toString methods for these two classes.\n\nThe class InheritancePointTester1 tests these classes and their methods. |
