Q#: Create a class Book that has the following data members:
- Name
- ISBN
- Author
- Edition
Create a constructor to initialize all data members. Write a method PrintInfo to print information containing the fields of class.
Write another class called Library that must contain a Main method. Inside Main, make at least 10 instances of Book, stored in an array (or list) of type Book. Call the method printInfo() for each instance. (Hint: use of foreach loop will be beneficial).

- Define a class called Country. A Country has populationSize, area, capital, currency, and abbreviation (2-3 letters taken from the country name). Define at least two constructors, at least two getter methods, at least two setter methods, and Override the toString() method and the equals() method. The equals() method must return true if the two countries have the same name and same area and false otherwise. 1) Write a main method, define an array of country objects 2) Display countries whose populationSize is greater than one million.1. Square Roots Create a class with a method that, given an integer, returns an array of double-precision floating point numbers (known in Java as double), each of which is a square root of a number between 2 and the parameter to the method. For example, if the parameter is 5, the method should return an array of 4 doubles, with approximate values 1.4142135623, 1.7320508075, 2.0, and 2.2360679774. Your method should check the validity of the parameter, and take appropriate action if the parameter is invalid. 2. Reading Files Create a class with a method that, given a string representing a file name, returns an integer with the number of characters in the file. For example, if the file has 10 characters, your method must return the number 10. 3. Main Class Create a class HW1.java with a main method that does both of the following: calls the method from part 1 with a random integer between 0 and 10, and prints each of the numbers in the result. The numbers should all be printed on the…10.5 LAB: Count probations (EO) Students are put on probation if their GPA is below 2.0. Complete the Course class by implementing the countProbation() method, which returns the number of students with a GPA below 2.0. Given classes: Class Course represents a course, which contains an ArrayList of Student objects as a course roster. (Type your code in here) Class Student represents a classroom student, which has three fields: first name, last name, and GPA. Hint: Refer to the Student class to explore the available methods that can be used for implementing the countProbation() method. Ex: If the following students and their GPA values are added to a course: Henry Cabot with 3.2 GPABrenda Stern with 1.2 GPALynda Robison with 3.3 GPAJake Flynn with 1.8 GPA then the countProbation() method returns 2 and the program output is: Probation count: 2 Course.java import java.util.ArrayList; public class Course { private ArrayList<Student> roster; // Collection of Student…
- Complete the Course class by implementing the courseSize() method, which returns the total number of students in the course. Given classes: Class LabProgram contains the main method for testing the program. Class Course represents a course, which contains an ArrayList of Student objects as a course roster. (Type your code in here.) Class Student represents a classroom student, which has three fields: first name, last name, and GPA. Ex. For the following students: Henry Bendel 3.6 Johnny Min 2.9 the output is: Course size: 2 public class LabProgram { public static void main (String [] args) { Course course = new Course(); // Example students for testing course.addStudent(new Student("Henry", "Bendel", 3.6)); course.addStudent(new Student("Johnny", "Min", 2.9)); System.out.println("Course size: " + course.courseSize()); } } public class Student { private String first; // first name private String last; // last name private…1. Create a class Employee with parameters name, id, designation, and basicSalary. Use appropriate datatypes and access specifiers. Use default constructor to create objects of employee. Write methods toset and get the values of parameters of employee. Write methods to find total salary of employee andto display the complete details of employee along with total salary. Create another class TestEmployeewhich creates array of n number of employees, uses appropriate set methods to set the values ofparameters of every employee. Display the details of each employee. (Total salary = basic salary + 80%of basic salary)Complete the following code for a method that returns the number of elements in an array of objects of the described ??????? class with an average that is less than 75 public int count(practice[] aArray) { int count = 0; for (int x = 0; x < aArray.length; x++) { if (_____) { ______; } } return count; }
- Design a generic method 'sum' that accepts an array of any type such as int, double or float and this method will return the sum of all elements in the array. Create a test class and call 'sum twice by passing arrays of different types.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.Please use java only and public int method. Show the steps with the pictures also. In this assignment, you will implement a class calledArrayAndArrayList. This class includes some interesting methods for working with Arrays and ArrayLists. For example, the ArrayAndArrayList class has a “findMax” method which finds and returns the max number in a given array. For a defined array: int[] array = {1, 3, 5, 7, 9}, calling findMax(array) will return 9. There are 4 methods that need to be implemented in the A rrayAndArrayList class: ● howMany(int[] array, int element) - Counts the number of occurrences of the given element in the given array. ● findMax(int[] array) - Finds the max number in the given array. ● maxArray(int[] array) - Keeps track of every occurrence of the max number in the given array. ● swapZero(int[] array) - Puts all of the zeros in the given array, at the end of the given array. Each method has been defined for you, but without the code. See the javadoc for each…
- 10. Write a static void method named raiseAllDesksToHighest The method should accept an array of StandingDesk references. If the array reference is null, or the array is empty the method can return without doing anything. Otherwise it should adjust the heights of standing desks in the array so that they all have the height of the highest desk in the array.Please use java. Show the steps with pictures. In this assignment, you will implement a class calledArrayAndArrayList. This class includes some interesting methods for working with Arrays and ArrayLists. For example, the ArrayAndArrayList class has a “findMax” method which finds and returns the max number in a given array.
