| 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. For each class, write the class declaration, the constructor, the toString method, and a method to move (translate) the point, i.e., shift the point's location by the specified amount.\n\nThe class InheritancePointTester2 tests these classes and their methods. |
