✓ Exercises Exercise: Write a method _ and _ that computes the region representing the intersection of two regions. Exercise: Write a method _contains__, which checks whether a n-dimensional point belongs to the region. Remember, a point belongs to the region if it belongs to one of the rectangles in the region. ✓ Membership of a point in a region #@title Membership of a point in a region def region_contains (self, p): ### YOUR SOLUTION HERE Region._contains = region_contains [ ] # Tests 10 points. assert (2, 1) in Region (Rectangle((0, 2), (0, 3)), Rectangle((4, 6), (5,8))) assert (2, 1) not in Region (Rectangle((0, 1), (0, 3)), Rectangle((4, 6), (5, 8))) Exercise: Write a method _le_ for regions such that R <= S if the region R is contained in the region S. You can test this by checking that the difference between R and S is empty.
Observer pattern The PhoneModel class stores a phone number as a list of digits, and the Keypad class has this method: public void simulateKeyPresses(int numKeyPresses)(0 that allows the user to enter digits one at a time then save each digit in the list. The Screen wants to respond to each key being entered. Make the model notify the observers whenever a new digit is entered for the phone number. The first observer prints the newest digit out to the screen The second observer prints "Now dialing 12345678901.." out to the screen (where the number is the number the model has). Only the Screen class can print to the screen The model must be decoupled from the Other classes.
Library class: Fields: books as arraylist to store all the books available in the library B3 B1 B2 В4 B5 Constructor: Library() } : No parameterized constructor to create the books object Methods: 1. addBook(Book bookobj): to add a new book to the arraylist; send the book object as a parameter to this method. 2. searchBook(String name): search a book by a given name in the arraylist. if exits print bookX found; otherwise print not found!!! 3. RemoveBook(String name): to delete a book object from arraylist by a given name: Hint: you need to use iterator class and remove method. Book class: Fileds: bookld, bookname. Constructor: two parameterized constructor that accepts name a parameter Book(int ID, String name) ..... Methods: 1. Accessor method to return the name of the book 2. Mutator method to change the id of the book.

Java Programming Class Car Attributes (all private): vin: String (5 digits) make: String model: String year: int price: double Methods: Parameterized constructor for initializing a new Car instance Getters for all attributes toString method to display a Car's attributes Executable Class Create an array of at least ten Car objects. Be sure to use many with identical last years and different prices. Create an ArrayList from the array. Shuffle the ArrayList. Sort the ArrayList first by year and then by price. See page 790-791. Using the forEach method and a lambda expression, print all cars sorted as above. Create a LinkedList from the ArrayList. Create an iterator capable of cycling both forward and backward through the LinkedList. Iterate forward through the entire LinkedList but without generating any output. Then iterate backwards through the LinkedList to print the cars data.
dict1 = {(1,1,1):"red", (2,1,-1):"green", (0,-1,1):"red", (0,0,-2):"blue"}In this case, there are 2 red points, and their centroid is at ( (1+0)/2, (1-1)/2, (1+1)/2 ) = (0.5, 0, 1)Considering that in this example there is only one green and one blue point, they are representing the respective color's centroid. Hence, your function should return the following dictionary:{"red":(0.5,0.0,1.0), "green":(2.0,1.0,-1.0), "blue":(0.0,0.0,-2.0)}
Gradient FillIn this labwork are asked to write a GUI application again using AWT. This is a fairly easy labworkthat is more about getting used to synchronized online learning. You are expected to:• Draw two rectangles.• Both of them should be filled using GradientPaint() function of AWT. (Check out itsfunction definition that is listed below.)• The first gradient should be parallel to the diagonal of the first rectangle. The colorgradient should not be repeated (acyclic).• The second gradient should be horizontal. The color gradient should be repeated forthis one (cyclic).• You are free to choose the colors but other than that your output should be similar tothe example screenshot given below.
Double any element's value that is less than controlValue. Ex: If controlValue = 10, then dataPoints = {2, 12, 9, 20} becomes {4, 12, 18, 20}. import java.util.Scanner; public class StudentScores { public static void main (String [] args) { Scanner scnr = new Scanner (System.in); final int NUM_POINTS = 4; int [] dataPoints new int [NUM_POINTS]; int controlValue; int i; controlValue = scnr. nextInt (); for (i = 0; i < dataPoints.length; ++i) { = scnr.nextInt (); dataPoints [i] } /* Your solution goes here * / for (i = 0; i < dataPoints.length; ++i) { System.out.print (dataPoints[i] + %3D " ") ; } System.out.println ();
