Software Requirements: • Latest version of NetBeans IDE • Java Development Kit (JDK) 8 Procedure: 1. our progras from rhFactor non-static and private. Remove the constructor with two (2) parameters. 2o upply uncapsutation Make bloodType and 2. The names of the public setter and getter methods should be: • setBloodType() • setRhFactor() getBlood Type() getRhFactor() 3. Use the setter methods to accept user input. 4. Display the values by calling the getter methods. Sample Output: Enter blood type of patient: Enter the Rhesus factor (+ or -): O+ is added to the blood bank. Enter blood type of patient: B Enter the Rhesus factor (+ or -): B- is added to the blood bank.
4. class definition for Friend For the next version of the friends database (coming soon!), we want to use classes rather than dictionaries. Define a Friend class , where each Friend object will store that friend's name, height and favorite foods. The class should have an init method that takes in that friend's name and height. It should have an add favorite_food method that takes a string and adds that string to a set of favorite foods, and a number_of_favorite_foods method that returns the number of favorite foods for that friend. Sample runs should look like: >>> friend1 = Friend ("dweezil", 175) >>> friend1. add favorite food("borscht") >>> friend1.add favorite food("borscht") >>> friend1. add favorite food("bagel") >>> friend1.add_favorite food("banana") >>> friend1.number_of_favorite_foods () 3. >>> friend1.name 'dweezil' >>> friend1.height 175

inal Project In this project, you will be asked to implement a simple Java program that will maintain its data using a specific NoSQL database called MongoDB. In this program you will be asked to maintain an object called Product, each product will have the following attributes: + Product ID. + Product Name. + Product Description. + Product Price. You will be asked to implement two types of products. « Dimensional Products. * Weighted Products. For the products of type Dimensional, they will have two extra values that express the width and the length of the product stored. For the products of type Weighted, they will have one extra value that express the weight of the product stored. When the program runs, the following choices appear. 1- Show all Products. 2- Add Product. 3- Delete Product. 4- Update Product. 5- Replace Product. 6- Search Product. 7-Bxit. Enter your choice: Notes: 1- When the program starts, it should connect automatically to a Database that is called “DBCourse” and a…
4. class definition for Friend For the next version of the friends database (coming soon!), we want to use classes rather than dictionaries. Define a Friend class , where each Friend object will store that friend's name, height and favorite foods. The class should have an _init_ method that takes in that friend's name and height. It should have an add_favorite_food method that takes a string and adds that string to a set of favorite foods, and a number_of_favorite_foods method that returns the number of favorite foods for that friend. Sample runs should look like: >>> friend1 Friend("dweezil", 175) >>> friend1.add_favorite_food("borscht") >>> friend1.add_favorite_food("borscht") >>> friend1.add_favorite_food("bagel") >>> friend1.add_favorite_food("banana") >>> friend1.number_of_favorite_foods() 3 >>> friend1.name 'dweezil' >>> friend1.height 175
Dynamic Apex: Write test class for this apex code(Not required the output) You are working on the project in which you have to create the apex code in which your task is to define the objects dynamically by using the method argument which is api name in string and a map of string, string as a key value pair. Class Code: public static void modifySobjectData(String str , Map mapofString) { //Retrive the type of Sobject by using the getGlobalDescribe Schema.SobjectType targetType = Schema.getGlobalDescribe().get(str); //Initalize the Object Sobject newobject = targetType.newSobject(); for(String s :mapofString.keySet(O) { newobject.put(s, mapofString.get(s)); } System.debug('newObject' + newobject); //Perform the DML if(targetType != null) insert newobject; } }

Implement all the classes using Java programming language from the given UML Class diagram. Note: This problem requires you to submit just two classes: Customer.java, Account.java. Do NOT include "public static void main()" method inside all of these classes. Graders will be testing your classes, using the unit-testing framework JUnit 4. Customer - ID:int -name:String -gender:char 'm' or 'f' +Customer(ID:int,name:String, discount:int) +getID():int +getName ():String +getGender ():char +toString():String "name (ID)" The Customer class models, customer design as shown in the class diagram. Write the codes for the Customer class and a test driver to test all the public methods. Account
Question 1 Write a Python class named Histogram that keeps track of how many times each unique element in a given sequence occurs. This class will implement the following interface: • Histogram( sequence ) will create a histogram of all elements occurring in the given sequence. This class cannot use the dict or collections.Counter types to create instance or class variables in order to implement the following specifications! If it does, the grade for your solution will automatically be zero! However, in some cases, your code will have to return dictionaries. So note the difference between the two specifications! • get( element-None, default-e ) will return how many times given element occurs in the histogram. If no element is specified, then the get () function will retum a dictionary where keys are elements and values are number of times a given element occurs in the sequence provided to the initializer. For example, given h - Histogram( "aaabbc" ) then h.get( "b" ) should return 2,…
In this assignment, you are implementing a class from a model shown here. PlayingCard suit char value int + PlayingCard (s:char, v:int): + getSuit(): char + getValue(): int + setSuit (s:char):void + setValue(v:int):void + toString(): String +isMatch (p:PlayingCard): boolean PlayingCard ADT 1) The constructor takes 2 char values and initializes the value and suit of the PlayingCard. 2) Accessor functions for the suit and value (getters) 3) Mutator functions for the suit and value (setters) 4) A toString method that displays the PlayingCard in the format (value, suit). For example, a 10 of hearts would display as (10,H). Face cards should display K, Q, J, or A, for the values 13, 12, 11, 14, respectively. 5) An isMatch method that takes a PlayingCard p as an argument and returns true if p's suit or value match that of the calling object After writing the class, test each function in a main method before proceeding to the next steps. Once your class is fully tested, write a driver method…

The class diagram below shows an Order class that "has a" Customer and zero or more Items. Order class should contain private Customer m_cust; private ArrayList<Item> m_items; public Order(Customer cus t) public void additem(Item i) public String toString() Item class should contain private String m_desc private int m_qty private double m_price public Item(String des c, double price, int qty) public String toString() Customer class should contain private String m_first; private String m_last; public Customer(String first, String last) public String toString() Please create the Order, Customer, and Item classes shown above. I have provided you with a read-only Main class that you can use to test your code. When you have completed the Order, Customer, and Item classes, running the Main program should produce the following output: Order for Smith, Tom Order Items: Greeting Card: 1 at 1.5 Baseball Glove: 1 at 54.0 Notebook: 3 at 2.5 public class Main{ public static void…
