Java Consider the getArea method from the textbook shown below:public int getArea()if (width <= 0) { return 0; } // line #1if (widthTriangle smallerTriangle = new Triangle(width - 1); // line #3int smallerArea = smallerTriangle.getArea(); // line #4return smallerArea + width; // line #51) { return 1; } // line #2Assume that line #3 is changed to this:Triangle smallerTriangle - new Triangle (width);This would cause infinite recursion forO triangles with width equal to 1O triangles with width equal to 0triangles of any widthtriangles with width greater than or equal to 2

As we can see, 3rd line is- Triangle smallerTriangle=new Triangke(width) which will create object…

Implement a class that simulates a traffic light. The next method advances the color in the usual way, from green to yellow to red, then again to green. Provide two constructors, as described in the documentation of the public interface. Also supply a method that yields the number of times that this traffic light has been red. /** A simulated traffic light.*/public class TrafficLight{ private String color; private int reds; /** Constructs a green traffic light. */ public TrafficLight() { /* Your code goes here */ } /** Constructs a traffic light. @param initialColor the initial color "green", "yellow", or "red" */ public TrafficLight(String initialColor) { /* Your code goes here */ } /** Moves this traffic light to the next color. */ public void next() { /* Your code goes here */ } /** Returns the current color of this traffic light. @return the current color */ public String getColor() {…
*Create a rectangle class using all methods given below.* *Use Java* Class Rectangle will have the following instance variables: •x –a double that represents the x coordinate of the lower left vertex of the rectangle •y –a double that represents the y coordinate of the lower left vertex of the rectangle •width –a double that represents the width of the rectangle •height–a double that represents the height of the rectangle •color –a String that represents the color of the rectangle •filled –a boolean variable that is true if the rectangle is filled, and false if it is not Rectangle constructor: The constructor should be: Rectangle (double x, double y, double height, double width, String color, boolean filled) Parameters are, in order,the x and y coordinates of the lower left corner, the height, the width, and the color of the rectangle. The constructor should check that these values represent a valid rectangle. If they do, then it should initialize the rectangle to these values.…
Given the Solid class, extend it with: Pyramid Cylinder RectangularPrism Sphere Make sure to create the constructor and override the volume and surfaceArea methods. Also extend RectangularPrism with Cube. HINT: You can look up formulas for how to compute the volume and surface area of a certain type of shape online. ========================================== public class SolidTester{public static void main(String[] args){String name;double volume;double surfaceArea; // Pyramid constructor should take name, length, width, height// in that orderPyramid pyramid = new Pyramid("My pyramid", 1, 3, 5);name = pyramid.getName();volume = round(pyramid.volume(), 2);surfaceArea = round(pyramid.surfaceArea(), 2);System.out.println("Pyramid '" + name + "' has volume: " + volume +" and surface area: " + surfaceArea + "."); // Sphere constructor should take name then radiusSphere sphere = new Sphere("My sphere", 4);name = sphere.getName();volume = round(sphere.volume(), 2);surfaceArea =…

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…
