Implement a class Robot that simulates a robot wandering on an infinite plane
JAva
Implement a class Robot that simulates a robot wandering on an infinite plane. The robot is located
at a point with integer coordinates and faces north, south, east, or west. Supply methods:
public void turnLeft()
public void turnRight()
public void move()
public Point getLocation()
public String getDirection()
The turnLeft and turnRight methods change the direction but not the location. The move method moves
the robot by one unit in the direction it is facing. The getDirection method returns a string “N”, “S”,
“E”, “W”. For the new object, the initial location and facing should be specified. For the initial facing, 0
means north, 1 means east, 2 means south, and 3 means west.
A tester class, RobotTester, has been provided as follows to help you how to implement the Robot class.
Therefore, implement the Robot class such that the following RobotTester class can be executed without
any changes.
import java.awt.Point;
/**
A class to test the Robot class.
*/
public class RobotTester
{
/**
Tests the methods of the Robot class.
@param args not used
*/
public static void main(String[] args)
{
// Create a new Robot object with the initial position of (5,5) and
// initial direction to the East (1).
Robot robot = new Robot(new Point(5, 5), 1);
robot.move(); // 6, 5, 1
robot.turnRight(); // 6, 5, 2
robot.move(); // 6, 6, 2
robot.move(); // 6, 7, 2
robot.turnRight(); // 6, 7, 3
robot.move(); // 5, 7, 3
robot.move(); // 4, 7, 3
robot.turnLeft(); // 4, 7, 2
robot.move(); // 4, 8, 2
2
Point location = robot.getLocation();
System.out.println("Location: " + location.x + ", " + location.y);
System.out.println("Expected: 4, 8");
System.out.println("Direction: " + robot.getDirection());
System.out.println("Expected: S");
}
}
