Finally, display information for each of the remaining books.Python:Please read the following. The Game class The Game class brings together an instance of the GameBoard class, a list of Player objects who are playing the game, and an integer variable “n” indicating how many tokens must be aligned to win (as in the name “Connect N”). The game class has a constructor and two additional methods. The most complicated of these, play, is provided for you and should not be modified. However, you must implement the constructor and the add_player method. __init__(self,n,height,width) The Game constructor needs to initialize three instance variables. The first, self.n, simply holds the integer value “n” provided as a parameter. The second, self.board, should be a new instance of the GameBoard class (described below), built using the provided height and width as dimensions. The third, self.players, should be an initially empty list. add_player(self,name,symbol) The add_player method is provided a name string and a symbol string. These two values should be…

- Assignment: Enhancing Dice Roll Stats Calculator Program Introduction: The project involves creating a program to roll pairs of dice, gathering statistics on the outcomes. Probability differs in the roll of two dice compared to a single die due to varied combinations. Dice Roll Series: User greeted with "Welcome to the Dice Roll Stats Calculator!" and prompted to specify rolls. Java classes: DiceRoller, Indicator, Validator. DiceRoller: Arrays: rollSeries (captures results), statIndicators (stores statistical indicators). Constructor rolls dice as per user request. Methods collect stats and print the report. Indicator class: Contains dicePairTotal and dicePairCount. Displaying Results: Sort statIndicators array before display. Indicator objects sortable by dicePairCount (implements Comparable). Example output:-----------------------dicepair rolltotal count percent---- ------ --------7 5 50%10 2 20%4 2 20%2 1 10% Tasks:…CODE IN JAVA Please look at the attached image for the information about the format the code should be in The code should be in two different .java files one with getFirstName, getLastName and getZipCode; the other file would be containing the main method Design and implement an application that reads a sequence of up to 25 pairs of names and postal (zip) codes for individuals. Store the data in an object of a class called “NameAndZip”, designed to store a first name (String), last name (String), and a postal code (int). Create a driver class called “NameAndZipList”. Assume that each line of input will contain two strings followed by an integer value. You will then create an object for each line read in and store that object in an array of NameAndZip objects. After the Names and Codes have been entered, print the list in an appropriate format to the screen using the toString method in the NameAndZip class. To test the program enter 3 names and codes.JAVA Language Caesar Shift Question: Modify the Caesar class so that it will allow various sized shifts to be used, instead of just a shift of size 3.
