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.
addCourse: accepts an object of type Course as the first parameter and the idNum of the Student as the second parameter. The Course can be added only if the Student object with the specified idNum exists in the studentsList, Course does not exist in the coursesRegistered list for the Student, After adding the course, the number of credits, do not exceed 18. If the course is added successfully, return true, else return false.

DiceSet Class in Python Write a class named DiceSet that contains a list of Die objects. Fields dice a list of Die objects Methods __init__(self, dice_faces) The constructor should instantiate the dice list to an empty list if no parameters are set. The constructor should take a list of integers. Add one die to the dice set for each integer with the number of faces equal to the integer. pop_die(self, value) Remove and return the first die with the given value from the list. add_die(self, die) Adds the given die (of class Die) to the dice list. roll(self) Roll all the die objects in the list of dice and return their sum. die_values(self) Return a list of the int values (last rolls) of the dice in the list. __str__(self) returns a string version of a dice set. Example: "{[d3] 1, [d6] 4, [d12] 5, [d4] 3}"

Add the following methods to your Boat Race class: Write a method called add_racer which takes in a Boat object and adds it to the end of the racers list. The function does not return anything. Write a method called print_racers which loops through racers and prints the Boat objects. This function takes in no parameters (other than self) and returns nothing. Write a method called count that returns the number of racers. Write a method called race. The race function calls the move function for all of the racers in the BoatRace. Once all the racers have moved, call the print_racers method to display information about the progress of each boat. Then, check if any of the racer’s current_progress is greater than or equal to the race’s distance. If so, then return a list of all of the racers whose current_progress is greater than or equal to distance. If no racer has finished the race then repeat the calls to move and check until at least one racer has finished the race.…
Part 2. fill Method Define a method in simpy named fill. Its purpose is to fill a simpy's values with a specific number of repeating values. The fill method will have two parameters following self: 1. The float value you are filling the values list in with. 2. The int number of values to fill in. The fill method is procedure-like in that it returns None and mutates the object the method is called on. After calling fill, the length of the Simpy object's values should be equal to the second argument given to fill. For example, consider the following usage and expected printed output, given inline, below: twos = Simpy([]) twos.fill(2.0, 3) print("Actual: ", twos, Expected: Simpy([2.0, 2.0, 2.0])") twos.fill(2.0, 5) print("Actual: ", twos, " - Expected: Simpy([2.0, 2.0, 2.0, 2.0, 2.0])") mixed = Simpy([]) mixed.fill(3.0, 3) - Expected: Simpy([3.0, 3.0, 3.0])") print("Actual: ", mixed, mixed.fill(2.0, 2) print("Actual: ", mixed, Expected: Simpy ([2.0, 2.0])") Python

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.

Complete the Kennel class by implementing the following methods: addDog(Dog dog) findYoungestDog() method, which returns the Dog object with the lowest age in the kennel. Assume that no two dogs have the same age. Given classes: Class LabProgram contains the main method for testing the program. Class Kennel represents a kennel, which contains an array of Dog objects as a dog list. (Type your code in here.) Class Dog represents a dog, which has three fields: name, breed, and age. (Hint: getAge() returns a dog's age.) For testing purposes, different dog values will be used. Ex. For the following dogs: Rex Labrador 3.5 Fido Healer 2.0 Snoopy Beagle 3.2 Benji Spaniel 3.9 the output is: Youngest Dog: Fido (Healer) (Age: 2.0)
1. Square Roots Create a class with a method that, given an integer, returns an array of double-precision floating point numbers (known in Java as double), each of which is a square root of a number between 2 and the parameter to the method. For example, if the parameter is 5, the method should return an array of 4 doubles, with approximate values 1.4142135623, 1.7320508075, 2.0, and 2.2360679774. Your method should check the validity of the parameter, and take appropriate action if the parameter is invalid. 2. Reading Files Create a class with a method that, given a string representing a file name, returns an integer with the number of characters in the file. For example, if the file has 10 characters, your method must return the number 10. 3. Main Class Create a class HW1.java with a main method that does both of the following: calls the method from part 1 with a random integer between 0 and 10, and prints each of the numbers in the result. The numbers should all be printed on the…
