A vehicle assumes that the whole world is a 2-dimensional graph paper. It maintains its x and y coordinates (both are integers). The vehicle gets manufactured (constructed) at (0, 0) coordinate.
Subtasks:
1. Design a Vehicle2010 class which inherits movement methods from Vehicle and adds new methods called move UpperRight, UpperLeft, LowerRight, LowerLeft. Each of these diagonal move methods must re-use two inherited and appropriate move methods.
2. Write an “equals” method which tests if significant class properties are the same (in this case x and y).
Note: All moves are 1 step. That means a single call to any move method changes value of either x or y or both by 1.
