- JAva Implement a class Robot that simulates a robot wandering on an infinite plane. The robot is locatedat 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 movesthe 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, 0means 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 withoutany changes.import java.awt.Point;/**A class to test the Robot class.*/public class RobotTester{/**Tests the…Write a class CircularArrayQueue such that all the following methods are implemented: 1. enqueue 2. dequeue 3. first 4. isEmpty 5. size 6. toStringWrite static methods: public static double cubeVolume(double h) : h^3 public static double cubeSurface(double h) : 6h^2 public static double cylinderVolume(double r, double h) : hπr^2 public static double cylinderSurface(double r, double h) : 2rπh+2πr^2 that compute the volume and surface area of a cube with height h, and a cylinder with circular base with radius r and height h.
