- Create an array of objects of the Person class, of size 4. Create three objects of the Person class, with values, and assign the objects to the array. Loop through the array and print the name, job, and email of all Personobjects.1. Declare an array to save 4 Dog objects. The Dog class is provided below. Look into the Dog class and find what attributes are needed for a dog object. Then initialize five dogs with the following information: Lily, 5 years old Jacob, 2 years old Sugar, 8 years old Bush, 3 years old 2. Print out every dog using a for loop (use either regular for loop or for-each loop, your choice). But you may find when you print out, the name and age are not displayed. Why? 3. Fix this problem by implementing the toString method in the Dog class. Dog Class: public class Dog { private String name; private int age; public Dog(String name, int age) { this.name = name; this.age = age; } public void setName(String name) { this.name = name; } }Create an object called GSSArray. (It stands for growable self-sorting array)This object will manage an array of type int. Create a private variable for an array of type int. In the constructor for this object, take in an int value which will determine the starting size of the array. The constructor should also instantiate the array.Create a public method called insert, which will take in an int and find the location in the array where it belongs and insert it there. If the array is full, then before inserting the value, method insert should call private method increaseSize, which will create a new array which is double the size of the current array. Then it will copy the values from the original array into the new array and set the private variable to this new array.The array should keep track of how many of its indexes are filled. Create a private variable called lastindex which will be equal to the last index of the array that has a value.Create a public method delete, which will…
- Blackjack is a card game where the goal is to reach a score of 21. Create a java version of this game with the following requirements. Extend the JPanel class and create an array of 52 cards. Add four sets of numbers from 1 to 10. Use J for Jack, Q for queen, K for king, and A for ace. Jack through king will have a value of 10, and the ace will have a value of 11. Deal two cards to the user and two cards to the computer. Do not show the value of the computer's first two cards to the user. Add buttons Hit, Stay, and Reset. If the user selects the "Hit" button, randomly select one of the cards from the array, and give it to the user. (After selecting a card, do not reuse this index during the rest of the game.) If the dealer has less than 21, "hit" the dealer, too. When the user selects the "Stay" button, add up the card values. The winner is the person who is closest to 21 without going over. Name the class Blackjack.java.Complete the following Programming Assignment. Use good programming style and all the concepts covered to date. Submit the java file(s) electronically through Canvas by the due date via one (1) Zip file. Rainfall Class - Note: Do not write a class as specified regarding the array (below). Instead use two one-dimensional arrays of size 12 each (parallel arrays) and four methods to solve the problem as specified. One array will hold the names of the months and the other array will hold the rainfall in inches for the months. You will pass the appropriate array or arrays to the methods as needed. 1. Rainfall Class Write a RainFall class that stores the total rainfall for each of 12 months into an array of doubles. The program should have methods that return the following: • the total rainfall for the year • the average monthly rainfall • the month with the most rain • the month with the least rain Demonstrate the class in a complete program. Input Validation: Do not accept negative numbers…Write code for a test class with the following details:1. Create an object of each class mentioned in Question 3, assuming the values for the data members of each class. Create an array that takes the objects of ALL the classes as its elements. Write an enhanced for loop to display the object details. 2. the dealer in Question 4 decides to offer 2% percent discount on the commission at runtime. Write codewith explanation. 3. Add code to the test class that writes the invoice details of Question 6 to a txt document Syntax of the q3 code is given below: import java.util.*; class Car{ //class car String[] name; int reg_number,eng_number, chassis_num,status; String[] city, model, color, date_reg,date_arr,type; float price; float abstract calculate (float price); } class Dealer extends Car{ //inherits from Car String[] deal_name, deal_id, deal_add, deal_pno; float dealer_com ; float abstract calculate (float price) { dealer_com= 0.01*price +…
- Create a class containing the main method. In the main method, create an integer array and initialize it with the numbers: 1,3,5,7,9,11,13,15,17,19 Pass the array as an argument to a method. Use a loop to add 1 to each element of the array and return the array to the main method. In the main method, use a loop to add the array elements and display the result. Note: In the loops, use the array field that holds the length of the array and do not use a number for array length.1. Create a book object which contains at least four different attributes (it should contains the name of the book and the publication date). Use the notation which is given below: Define Book which made of { .anAttribute .anotherAttribute } 2. Create an array of Books consists of 5 books. 3. Write an algorithm which is determining whether or not some book’s name in the array. 4. Write an algorithm which is determining the oldest book in the array.C++ Programing NOTE: The important method has been ATTRIBUTES given to you. userld:int //generates unique id from 10001 upwards username:string firstname:string lastname:string dob:string INSTRUCTION 1 The program should generate unique userld whenever new object is created. Notice that idGenerator is static variable, so assign the current value of idGenerator to userld, so that each user will have unique user id (Starting from 10001). age: int idGenerator: static int; totalUsers : static int www МЕТНODS Then increment idGenerator by 1. INSTRUCTION 2 User() User(string, string, string, int) User(const User&) "User() The totalUsers is also a static variable. This should keep track of the total users in the class. With the Above UML for CLASS USER, answer the following questions
- -CLO3- Question No 1: (Array of primitive values) Initialize an array of double values of size 10, with user input. Then calculate and display the sum and average of these values. Question No 2: (Array of objects) Create a class Student having rollno and name as private instance variables. write a program that creates studentArray of five students; it then initializes all students rollno and name by using an input function that will initialize and return an array of five students. and display function that displays the values of all students the array which is passed to it.continue from first question, Client class:The client program will allow entry of these data for several different student into an ArrayList and then perform some analysis and queries.Your client class (program) will provide the user with a menu to perform the following operations. You will also need to load the information of the students from a CSV file (student.csv) before displaying the menu. You only need one ArrayList and one menu for this. For the csv file, your first item can be U or G to differentiate whether the entry is creating a UndergraduateStudent object, or a GraduateStudent object. You can then decide how you want other data to be listed in the csv file. You should specify clearly in your documentation the data format of the CSV files used in this assignment.1. Quit (exit the program)2. Add (to the ArrayList) all the marks information about an undergraduate or graduate student by reading it from another CSV file. Your program will ask for the file name.3. Given student…. Create a testEmployees class. Do the following: Declare an array called arrEmp of 10 Employee type objects in the main method.
