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()); } }

pet shop wants to give a discount to its clients if they buy one or more pets and at least five other items. The discount is equal to 20 percent of the cost of the other items, but not the pets.Use a class Item to describe an item, with any needed methods and a constructor public Item(double price, boolean isPet, int quantity)An invoice holds a collection of Item objects; use an array list to store them. In the Invoice class, implement methods public void add(Item anItem)public double getDiscount()Write a program that prompts a cashier to enter each price and quantity, and then a Y for a pet or N for another item. Use a price of –1 as a sentinel. In the loop, call the add method; after the loop, call the getDiscount method and display the returned value.
Write the definitions of the member functions of the classes arrayListType and unorderedArrayListType that are not given in this chapter. The specific methods that need to be implemented are listed below.
Implement the following methods in arrayListType.h:
isEmpty
isFull

That is, half the integers in the set are less than or equal to the median, and half the integers are greater than or equal to the median. For example, the median of {99, 1, 10, 6, 2} is 6 since 1 and 2 are smaller than 6 and 10 and 99 are larger than 6. Implement a method median( ) with no parameters that finds and returns the median of the integers in a data array. Use this keyword in meaningfully. Assume that the data array is an instance variable of Data class. Write a parameterized constructor to allocate and assign values to data array. Assume that the array has odd length. Write main () in a separate class constructor to use the Data class.arrow_forwardImplement the following class and write a driver classarrow_forward
- Use NetBeans Note for all the above User-Defined Classes: • Provide appropriate validation code so the right values get populated in the instance variables. For example, the payrate should not be negative. Write a Java application (Client) program with a static method called generateEmployees( ) that returns a random list of 10 different types of Employee objects. You would use an ArrayList to store the employee objects that will be returned. Use a for loop to populate randomly different types of employee objects with some random data. You could possibly think of a range of values like 1 – 4. If random value is 1, create a HourlyEmployee object with some randomly generated data, if 2, a SalariedEmployee object with some random data and so on. I would leave it to your ingenuity to generate and populate these different Employee objects with other data like name etc. As these objects are generated, add them to your data structure (array or ArrayList that you are using). Finally, the…arrow_forwardIt is often the case that two or more classes share a common set of methods. For programming purposes we might wish to treat the objects of those classes in a similar way by invoking some of their common routines.For example, the Dog and Cat classes listed below agree on the void method speak. Because Dog and Cat objects have the ability to “speak,” it is natural to think of putting both types of objects in an ArrayList and invoking speak on every object in the list. Is this possible? Certainly we could create an ArrayList of Dog that would hold all the Dog objects, but can we then add a Cat object to an ArrayList of Dog?Try running the main program below as it is written. Run it a second time after uncommenting the line that instantiates a Cat object and tries to add it to the ArrayList. import java.util.*;public class AnimalRunner{ public static void main(String[] args) { ArrayList<Dog> dogcatList = new ArrayList<Dog>(); dogcatList.add(new Dog("Fred"));…arrow_forwardIt is often the case that two or more classes share a common set of methods.

- Task 1:The first task is to make the maze. A class is created called Maze, in which a 2D array for the maze is declared. Your job is to implement the constructor according to the given javaDoc. When you completed this task, write a set of Junit test case to test your code.As you probably noticed, the maze is defined as a private variable. The second job for you is to write an accessor(getter) method that returns the maze. Other information about what is expected for this method is given in the starter code. public class PE1 { MazedogMaze; /** * This method sets up the maze using the given input argument * @param maze is a maze that is used to construct the dogMaze */ publicvoidsetup(String[][]maze){ /* insert your code here to create the dogMaze * using the input argument. */ }arrow_forwardA pet shop wants to give a discount to its clients if they buy one or more pets and at least five other items.

Add to your Animal class: Member: name Methods: Public Animal (String name) //constructor public void makes Sound () with the implementation printing out a generic animal sound. Next, override (add) the makes Sound() method to your Cat and Dog class, with the implementation specific to each animal (i.e, cat says purr..). Do not override the makesSound() for your Dragon (bearded dragons don't make sounds!) Note, you'll also need a constructor in each of your subclasses which calls super(name) to initialize the common 'name' member of Animal. Next (in your test harness) create a List of different Animals ( a couple cats, a dog, a dragon... ) and add these Animals to your list. Iterate through your list & call makeSound on each. (you should observe the makeSound method called will be: cat -> from Cat class, dog-> from Dog class, bearded Dragon -> from Animal class ) EC:…arrow_forward
- public interface Rational { /** Determines whether this Rational object represents a value less than one. * @return true if this Rational is less than 1, false else public boolean islessThanOne (); } Write the class Goo that implements this interface. Goo must use an array. Your answer must include all necessary fields and any additional private methods as needed for your implementation. You may not use ArrayList, or any similar class.arrow_forwardThe play method in the Player class of the craps game plays an entire game without interaction with the user. Revise the Player class so that its user can make individual rolls of the dice and view the results after each roll. The Player class no longer accumulates a list of rolls, but saves the string representation of each roll after it is made. Add new methods rollDice, getNumberOfRolls, isWinner, and isLoser to the Player class. The last three methods allow the user to obtain the number of rolls and to determine whether there is a winner or a loser. The last two methods are associated with new Boolean instance variables (winner and loser respectively). Two other instance variables track the number of rolls and the string representation of the most recent roll (rollsCount and roll). Another instance variable (atStartup) tracks whether or not the first roll has occurred. At instantiation, the roll, rollsCount, atStartup, winner, and loser variables are set to their appropriate…arrow_forwardLet's get some more practice with algorithms by escaping from a maze! Implement a public class Maze Escape that provides a single public class method named escape. escape accepts a single parameter, a Maze object with methods explained below. Your goal is to manipulate the maze until you reach the exit, and then return it when you are finished. If the passed maze is null, throw an IllegalArgumentException. To navigate the maze, using the following Maze methods: • isFinished (): returns true when you have reached the exit of the maze • turnRight () rotates your character 90 degrees to the right • turnLeft() rotates your character 90 degrees to the left • canMove () returns true if you can move one cell forward, false otherwise. Your path may be blocked by a wall! • move () moves your character one cell forward and increases the step counter The passed Maze object represents a simply-connected or perfect maze: one that contains no loops. As a result, we suggest that you pursue a classic…arrow_forward
