This question involves the implementation of a Position class. A Position object is created with two parameters representing a position on a 2d grid, with the first value giving the position on a east/west axis, where east is positive, and the other on an north/south axis where north is positive. The position class supports movement of the current position north, south, east and west, reporting of the current position as a String and reporting of the total distance traveled. The Position class provides a constructor and the following methods. move changes the position by the number specified in the first (double) parameter in the direction given by the second (String) parameter (precondition: this is equal to one of N, S, E, W). If none of these 4 directions are given, does nothing toString returns the current position as a String formatted as a pair of coordinates totalDistance returns the total distance the position has been moved as a double The following table contains a sample code execution sequence and the corresponding results. Comment Statements and Expressions Value Returned (blank if no value) Position p = new Position (1.5, -5.0); p.toString(); (1.5, -5.0) This is the starting position p.totalDistance(); 0.0 No movement so far p.move (3.5, "E"); Moves the position 3.5 east p.move (1.0, "S"); p.toString(); (5.0, -6.0) p.totalDistance(); 4.5 p.move (8.2, "N"); Moves the position 3.5 south East/west axis value has increased by 3.5, north/south axis value has decreased by 1.0 Total distance traveled is 3.5+1.5 = 5.0 Moves the position 8.2 north Moves the position 3.7 west Moves the position 0.6 west East/west axis value has increased by 3.5, north/south axis value has decreased by 1.0 Total distance traveled is 4.5+8.2+3.7+0.6 = 17.0 p.move (3.7, "W"); p.move (0.6, "W"); p.toString(); (0.7, 2.2) p.totalDistance(); 17.0 Write the complete Position class including the constructor and any required instance variables and methods. Your implementations must meet all specifications and conform to the example
