Update Bresenham's line (JAVA) method such that you can scale the line before drawing it. Normally, you pass two points and a Graphics' object to draw line using Bresenham's algorithm. Now you'll add scaling factors in arguments for scaling as shown below. public void drawBresenhamline(Point p1, Point p2, double Sx, double Sy, Graphics g) { I/Write your code here Note:If you use scaling method, then also write Scale method in solution.

When I write the code here to visual studio, I get errors and I don't know how to fix it. Please examine it in detail and I would appreciate it because I have no right to ask any more questions. class Main { public class GameManagement { // This class holds all the team & score management private List<Team> teams = new ArrayList<Team>(); private int countTeam; private static int MAX_TEAMS=8; public GameManagement (){ try { FileReader fr = new FileReader("player.txt"); // reading from the text file Scanner in = new Scanner(fr); while (in.hasNextLine()){ String line = in.nextLine(); Team team = new Team(line); teams.add(team); } } catch (...) {} } public List<Team> getTeams(){ return teams; } } public class GameTournamentGUI extends JFrame { GameManagement manager…
Implement the following class. Refer to the below notes for more details. SimCard phoneNumber: String internationalService: boolean minutes: int // default 0 costPerMinute: double + SimCard ( ) + SimCard ( newPhoneNumber: String, newInternationalService: boolean ) + getters and setters of phoneNumber, internationalService and costPerMinute + callLocal (duration: int): void + callInternational(duration: int): boolean + bill(): double o phoneNumber: private String representing the phone number. Default is "00-000000" o internationalService : private boolean indicating whether international calls are allowed or not. Default is false. o minutes: private int representing the number of minutes to be invoiced (added to the bill). Default is 0. o costPerMinute: private double representing the cost of 1 minute. This value should be positive. Default value is 0.2. Assume all the sim card has the same cost rate per minute. LS) The no-arg constructor that will create a new SimCard with the default…
also need help Write a second constructor that takes a String array of pages as input and sets the String array instance variable equal to the input. Continue to default the page number to zero. Part 2: Write a getter and a setter method for the current page number variable. The setter should check to make sure that the input is a valid page number and only update the variable if the new value is valid. Part 3: Write a getCurrentPage method that returns the String of the current page indexed by current_page. public class Ebook{ private String[] pages; private int current_page; //constructor public Ebook() { this.pages = {"See Spot.", "See Spot run.", "Run, Spot, run."}; this.current_page = 0; }}
A pentagonal number is defined as n(3n−1) ∕ 2 for n = 1, 2, . . ., etc.. Therefore, the first few numbers are 1, 5, 12, 22, . . . . Write a method with the following header that returns a pentagonal number:public static int getPentagonalNumber(int n) For example, getPentagonalNumber(1) returns 1 and getPentagonalNumber(2) returns 5. In Java, Write a test program that uses this method to display the first 100 pentagonal numbers with 10 numbers on each line. Numbers are separated by exactly one space.
Java program I need help creating a program that creates these two Christmas trees. It has a method that accepts two parameters (one for the number of segments and one for the height of each segment). The left tree has 3 segments with a height of 4 and the right one has two segments with a height of 5. If you could explain it, that would be great, I really want to understand how you do it.
1.A) The median of a set of integers is the middle-most integer in size. That is, half the integers in the set are less than or equal to the median, and half the integers are greater than or equal to the median. For example, the median of {99, 1, 10, 6, 2} is 6 since 1 and 2 are smaller than 6 and 10 and 99 are larger than 6. Implement a method median( ) with no parameters that finds and returns the median of the integers in a data array. Use this keyword in meaningfully. Assume that the data array is an instance variable of Data class. Write a parameterized constructor to allocate and assign values to data array. Assume that the array has odd length. Write main () in a separate class constructor to use the Data class.
Create a class called SquareTester that will create a Square object. Print out the toString method with the object as your receiver. Print out the perimeter using the getArea method and the object as your receiver. public class SquareTester { public static void main(String{}args) { //create your Square object with any value as your argument //print the toString method //print the area of the square on a new line -ex: “The area is: 64” } }
Please see the snip for the detail. Note: The polygon have to rotate clockwise in same also counterclock wise have to rotate: here is my code it have issue it only rotate to clockwise but in same time have to rotate to the counterclockwise too but it not plesase fix it or write from new. my code: import turtle as t import math class CenteredPolygon: def __init__(self, n, size, center=(0, 0), pen=None, **kwargs): self.numsides = n self.size = size self.center = center self.corners = [] self.pen = pen if pen is not None else self.init_pen(**kwargs) self.draw() def init_pen(self, **kwargs): pen = t.Turtle() for key, value in kwargs.items(): try: f = getattr(pen, key) f(value) except Exception as e: print(e) return pen def set_corners(self) -> list: p = self.pen p.pu() p.goto(self.center) for i…
This challenge is based on the classic videogame "Snake". Assume the game screen is an n * n square, and the snake starts the game with length 1 (i.e. just the head) positioned on the top left corner. For example, if n = 7 the game looks something like this: BEGINNING In this version of the game, the length of the snake doubles each time it eats food (e.g. if the length is 4, after eating it becomes 8). Create a function that takes the siden of the game screen and returns the number of times the snake can eat before it runs out of space in the game screen. Examples FIRST MOVE snakefill (3) snakefill (6) - 5 snakefill (24) → 9 3

Print numbers 0, 1, 2, ..., userNum as shown, with each number indented by that number of spaces. For each printed line, print the leading spaces, then the number, and then a newline. Hint: Use i and j as loop variables (initialize i and j explicitly). Note: Avoid any other spaces like spaces after the printed number. import java.util.Scanner;public class NestedLoop {public static void main (String [] args) {Scanner scnr = new Scanner(System.in);int userNum;int i;int j; userNum = scnr.nextInt();
Complete the convert() method that casts the parameter from a double to an integer and returns the result.Note that the main() method prints out the returned value of the convert() method. Ex: If the double value is 19.9, then the output is: 19 Ex: If the double value is 3.1, then the output is: 3 code: public class LabProgram { public static int convert(double d){ /* Type your code here */ } public static void main(String[] args) { System.out.println(convert(19.9)); System.out.println(convert(3.1)); }}
