Create a class named after your last name (e.g., Hasanov) with the following methods and requirements: • it should have a String member called firstName with the initial value of your first name (e.g., Ismayil) • methodShuffie0 should concatenate your first name with itself, upcase and print by removing first and third letters in the next line until 1 or 2 letters left. (e.g., for Ismayil: O "ISMAYILISMAYIL" O "SAYILISMAYIL" O "AILISMAYIL" O "IISMAYIL" O "IMAYIL" O "MYIL" O YL" main) method should test the above method Submit your final java file in the below text field.

Create a class called Pizza (Pizza.java). It should have the following private data members: String size: size of the pizza could be small, medium, or large int numofToppings: number of toppings could be 1, 2 or 3. double price and should provide the following methods: default constructor (set size to an empty string, numOfTopping and price to 0) non-default constructor Pizza(String s, int n, double p) getters and setters for the three data members method toString() returns a string representing the Pizza object, formatted as: Size: large Toppings: 2 Price: 9.95 method equals(Object obj) to indicate some other object is "equal to" this one public class Pizza { Complete the following unit test for the class Pizza described above. Make sure to test each public constructor and each public method, print the expected and actual results. // Start of the unit test of class Pizza public class PizzaTester { public static void main() { // Your source codes are placed here
5. Complete the class code below and include a method named partition which takes an integer array and a partition integer as parameters and then partitions the original array into two new arrays where elements of the first array are all less than or equal to the partition integer and the second array are all greater than the partition integer. The method should print the original array, followed by the lower partition and finally the upper partition. Nothing should be returned by the method. For example, given int[ ] arr = {1, 45, 16, 7, 39, 6, 5, 11, 72, 31, 15} a method call to partition(arr, 11) should output: %3D [1, 45, 16, 7, 39, 6, 5, 11, 72, 31, 15] [1, 5, 6, 7, 11] [15, 16, 31, 39, 45, 72] public class Partition { public static void main(String[] args) { int[] arrayToPartition = {1, 45, 16, 7, 39, 6, 5, 11, 72, 31, 15}; %3D int partitionNumber = 11; partition(arrayToPartition, partitionNumber); } /l your method code here } // end of Partition class

5. CODE IN PYTHON Create a BankAccount class which has an __init__ method which accepts an account name and starting balance to store as instance fields. The class should also have a method to deposit money, a method to withdraw money, and a method called "get_balance" which returns a string of the format "{account_name} has a balance of {balance}" (do not print this out from within the class, just return the string). In the same file, create an instance of the BankAccount class with a hardcoded name and starting balance. Deposit any amount to the account and withdraw any amount from the account (both can be hardcoded) and then print the result of calling the get_balance method on the instance.
7. Write a Temperature class that represents temperatures in degrees in both Celsius and Fahrenheit. Use a floating-point number for the temperature and a character for the scale: either 'C' for Celsius or 'F' for Fahrenheit. The class should have · Four constructors: one for the number of de- grees, one for the scale, one for both the de- grees and the scale, and a default construc- tor. For each of these constructors, assume zero degrees if no value is specified and Cel- sius if no scale is given. · Two accessor methods: one to return the temperature in degrees Celsius, the other to return it in degrees Fahrenheit. Use the for- mulas from Practice Program 5 of Chapter 3 and round to the nearest tenth of a degree. • Three set methods: one to set the number of degrees, one to set the scale, and one to set both. • Three comparison methods: one to test whether two temperatures are equal, one to test whether one temperature is greater than another, and one to test whether one temper-…
Create a class Course, which has one field: String courseName Create the constructor, accessor, and mutator for the class. Then, in the main method of this class, create an instance of the class with the name "CST1201". Write an equivalent while statement to replace the following for statement for (int i=2; i<100; i=i+2) { System.out.println(i); }
1. Create a properly encapsulated class named Person that has the following: A String instance variable called name. A constructor that takes a String parameter and sets the instance variable. A properly named getter for the instance variable. A correctly overrided equals method which returns true if the name instance variable of the parameter and the reference variable calling the method are equal. (Do not forget the null and class type checks!) Compile your Person class. 2. Create a properly encapsulated class named Employee that inherits from Person and has the following: ● ● ● A String instance variable called office (e.g. "LWH 2222"). A String instance variable called hourlywage (e.g. "$45.15"). A constructor that takes three Strings as parameters for name, office, and hourlyWage and sets the instance variables of both the parent class and the Employee class. An overridden toString method that returns the concatenation of name and hourlyWage instance variables (separated by a…
In python and include doctring: First, write a class named Movie that has four data members: title, genre, director, and year. It should have: an init method that takes as arguments the title, genre, director, and year (in that order) and assigns them to the data members. The year is an integer and the others are strings. get methods for each of the data members (get_title, get_genre, get_director, and get_year). Next write a class named StreamingService that has two data members: name and catalog. the catalog is a dictionary of Movies, with the titles as the keys and the Movie objects as the corresponding values (you can assume there aren't any Movies with the same title). The StreamingService class should have: an init method that takes the name as an argument, and assigns it to the name data member. The catalog data member should be initialized to an empty dictionary. get methods for each of the data members (get_name and get_catalog). a method named add_movie that takes a Movie…
A. Build a class named car. This class is defined as follows: It has the fields: Car ID, Car model, Car make, Car color, Car year. Build a constructor that accepts the five parameters (Car ID, Car model, Car make, Car color, Car year). Override the method toString() to return the string representation of Car ID, Car model, Car make, Car color, Car year. Build a method named display to print the values returned by toString() method. Override the equals() method to compare the Car model, Car make, Car color of two Car objects. The method returns true if all the values of these fields are the same, and false otherwise. In the equals method you must check the following: a. If you compare the Car object to itself, return true.! b. If you compare car object with another car object return true, otherwise return false. Hint use : instanceof operator for this purpose. Override the hashcode() method to return same hash codes for objects that are equal according to the equals() method you built…

!! E! 4 2 You are in process of writing a class definition for the class Book. It has three data attributes: book title, book author, and book publisher. The data attributes should be private. In Python, write an initializer method that will be part of your class definition. The attributes will be initialized with parameters that are passed to the method from the main program. Note: You do not need to write the entire class definition, only the initializer method lili lilı
