Question

Java Program

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, east, south, 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", "E", "S", or "W"

Explanation / Answer

public class Robot {
private String direction;
private Point location;

public Robot() {
direction="N";
location=new Point(0, 0);
}
  
public void turnLeft(){
if(direction.contentEquals("N")){
direction="W";
}else if(direction.contentEquals("W")){
direction="S";
}else if(direction.contentEquals("S")){
direction="E";
}else if(direction.contentEquals("E")){
direction="N";
}
}
  
public void turnRight(){
if(direction.contentEquals("N")){
direction="E";
}else if(direction.contentEquals("W")){
direction="N";
}else if(direction.contentEquals("S")){
direction="W";
}else if(direction.contentEquals("E")){
direction="S";
}
}
  
public void move(){
if(direction.contentEquals("N")){
location.y=location.y+1;
}else if(direction.contentEquals("W")){
location.x=location.x-1;
}else if(direction.contentEquals("S")){
location.y=location.y-1;
}else if(direction.contentEquals("E")){
location.x=location.x+1;
}
}

public String getDirection() {
return direction;
}

public Point getLocation() {
return location;
}
  
}
