Implement a class Robot that simulates a robot wandering on an
infinite plane with m*n tiles. The
robot is located at a point with integer coordinates (x,y) and
faces north (0), east(1), south(2), or
west(3). Supply methods
public void turnLeft()
public void turnRight()
public void move()
public Point getLocation()
public String getDirection()
public String toString()
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", "E", "S", or "W". You can define necessary data members in the
class.
a) (6 points) Write the definition of a class Robot based on the
requirements above.
b) (2 points) Write a program that tests various operations of
the class Robot.
c) (2 points) What is the difference between overloading a
method name and overriding a method name?
