Chapter 8, Problem 17E
Create a class ShuffleCipher that implements the interface MessageEncoder, as described in Exercise 15. The constructor should have one parameter caned n. Define the method encode so that the message is snuffled n times. To perform one shuffle, split the message in hair and then take characters from each half alternately. For example, if the message is abcdefghi, the halves are abcde and fghi. The shuffled message is afbgchcie. (Hint. You may wish to define a private method that performs one shuffle.)

write a java method with followin instraction :
Write a method called prioritizeQueue to give priority for vaccination for elderly persons. The method is to be in a class called VaccinationQueue and has two parameters q1 and q2 type ArrayQueue. The q1 and q2 data are of type Integer. Assume that initially q1 is not empty and q2 is empty. The method will insert from q1 those elements towards the beginning of the queue (front) q2 whose data is greater than or equal to 45 and will insert those elements whose data is less than 45 and greater than or equal to 18 towards the end (rear) of q2. Any data item less than 18 of q1 will not be inserted in q2. It returns the number of elements added to q2.
Class ArrayQueue and all its methods including iterator are available for use. You can also create temporary queues. You are not allowed to use arrays or any other data structure.
Example:
Before method call:
front rear
q1: 14 25 50…

Use only NumPy to create the Normalize Class: Image Normalization is a technique used to touch up images that are too dark or too light for the human viewing experience. Implement a version that outputs images with full dynamic range (0–255 pixel intensity). In other words, for each color channel (r, g, b), rescale the range of pixel values for that channel to include both 0 and 255. After normalizing, there should be at least one pixel with a red value of 0, at least one pixel with a red value of 255, at least one pixel with a green value of 0, etc. To normalize a list of numbers nums to the range 0–n, set nums[i] = (nums[i]−min(nums))/(max(nums)−min(nums))∗n for all i. Be careful! When max(nums) == min(nums), you should not touch that list (why?).
Make a recursive method for factoring an integer n. First, find a factor f, then recursively factor n / f. This assignment needs a resource class and a driver class; these two classes will need to be in two separate files. The resource class will contain all of the methods and the driver class only needs to call the methods. The driver class needs to have only 5 lines of code. The code needs to be written in Java.

- Create a class with a method. The method has to decide whether a given year is a leap year or not. Note- A year is a leap year if: • It has an extra day i.e. 366 instead of 365. It occurs in every 4 year e.g. 2008, 2012 are leap years. For every 100 years a special rule applies-1900 is not a leap year but 2000 is a leap year. In those cases, we need to check whether it is divisible by 400 or not. > > ClassAssignmentEx2 ©LeapYearDecider javaclassnotes.assignments javaclassnotes.assignments ClassAssignmentEx2() LeapYearDecider() main(String):void A isLeapYear(int):booleanarrow_forward1.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.arrow_forwardMethods in Java Write a program that accepts three strings: first name, last name, age, and nationality.

- JAVA and use the code at the bottom 28.7 LAB: Acronyms An acronym is a word formed from the initial letters of words in a set phrase. Define a method named createAcronym that takes a string parameter and returns the acronym of the string parameter. Append a period (.) after each letter in the acronym. If a word begins with a lower case letter, don't include that letter in the acronym. Then write a main program that reads a phrase from input, calls createAcronym() with the input phrase as argument, and outputs the returned acronym. Assume the input has at least one upper case letter. Ex: If the input is: Institute of Electrical and Electronics Engineers the output should be: I.E.E.E. Ex: If the input is: Association for computing MACHINERY the output should be: A.M. Although the letters ACHINERY in MACHINERY are upper case, those letters are omitted for being a part of the word MACHINERY. The program must define and call a method:public static String createAcronym(String…arrow_forwardLet's get some more practice with algorithms by escaping from a maze! Implement a public class Maze Escape that provides a single public class method named escape. escape accepts a single parameter, a Maze object with methods explained below. Your goal is to manipulate the maze until you reach the exit, and then return it when you are finished. If the passed maze is null, throw an IllegalArgumentException. To navigate the maze, using the following Maze methods: • isFinished (): returns true when you have reached the exit of the maze • turnRight () rotates your character 90 degrees to the right • turnLeft() rotates your character 90 degrees to the left • canMove () returns true if you can move one cell forward, false otherwise. Your path may be blocked by a wall! • move () moves your character one cell forward and increases the step counter The passed Maze object represents a simply-connected or perfect maze: one that contains no loops. As a result, we suggest that you pursue a classic…arrow_forwardPYTHON CLASSES AND OBJECTarrow_forward

As the ball rolls down, it strikes a spike and bursts open to release a number of smaller balls (in our simulated game, the number of smaller balls is a randomly generated integer between 2 and 6, inclusive). As the smaller balls further roll down, when one strikes a spike, that ball and all its sibling balls burst and each generates another set of smaller balls (using the same random number already generated for the first roll). The balls keep rolling downhill and striking spikes and bursting into smaller balls until a golden ball is released by one of the bursts. At this time, the game is over and the player is told how many balls were generated during the last burst (including the golden ball). The game is played by two players at a time and the player who had the lowest number of balls generated on the…arrow_forward
