Class PassengerList has/should have the following members: - A list of valid PNR numbers pnrList as an instance variable. - Constructor PassengerList () populates the list pnrList as given in the template code. -Method public PassengerInfo getPassenger Info (String) should take a PNR number as argument, check if the PNR number is valid, and if yes, then return a valid PassengerInfo object that has the name of the passenger. For ease of implementation, we assume that the valid PNR numbers are 1 to 3. - An inner private class Passenger Info - Name of a passenger as an instance variable - This class implements interface IPassengerInfo, which enables its object to be accessible from outside the class PassengerList. - Constructor PassengerInfo (String) assigns the name of the passenger to the instance variable of class PassengerInfo whose PNR number is given. If the PNR number is 1, then the name should be Passenger 1, where the valid PNR numbers are for 1 ranging from 1 to 3.

Consider the following class hierarchy: class Animal { ... } class Mammal extends Animal { ... } class Cat extends Mammal { ... } Write a generic method printArray that takes an array of any type and prints each element of the array. If the element is an instance of Animal or its subclass, the method should call the toString method of the object to print its details. Otherwise, the method should simply print the element. Your method should have the following signature: public static <T> void printArray(T[] array)
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 listSize maxListSize clearList Copy constructor Implement the following method in unorderedArrayListType.h insertAt Also, write a program (in main.cpp) to test your function.
Start with this class declaration: class Student { int sId; String name; double gpa;} Implement a Comparable and Comparator interface to provide the following three (3) alternative ways of ordering for the Student objects - based on sId (i.e., assume that this is selected as the natural ordering)- based on name, - based on gpa. Next declare a list of five Student objects, initialize them with random values. Test your code by printing out each of the following on separate lines: (original list of students, sorted list of students in ascending sId order, sorted list of students in ascending name order, sorted list of students in ascending gpa order).
Create a generic class with a type parameter that simulates drawing an item at random out of a box. This class could be used for simulating a random drawing. For example, the box might contain Strings representing names written on a slip of paper, or the box might contain Integers representing a random drawing for a lottery based on numeric lottery picks. Create an add method that allows the user of the class to add an object of the specified type along with an isEmpty method that determines whether or not the box is empty. Finally, your class should have a drawItem method that randomly selects an object from the box and returns it. If the user attempts to drawn an item out of an empty box, return null. Write a main method that tests your class.
Complete the Kennel class by implementing the following methods: addDog(Dog dog) findYoungestDog() method, which returns the Dog object with the lowest age in the kennel. Assume that no two dogs have the same age. Given classes: Class LabProgram contains the main method for testing the program. Class Kennel represents a kennel, which contains an array of Dog objects as a dog list. (Type your code in here.) Class Dog represents a dog, which has three fields: name, breed, and age. (Hint: getAge() returns a dog's age.) For testing purposes, different dog values will be used. Ex. For the following dogs: Rex Labrador 3.5 Fido Healer 2.0 Snoopy Beagle 3.2 Benji Spaniel 3.9 the output is: Youngest Dog: Fido (Healer) (Age: 2.0)
Design a class template, Collection, that stores a collection of Objects(in an array), along with the current size of the collection. Provide publicfunctions isEmpty, makeEmpty, insert, remove, and contains.contains(x) returns true if and only if an Object that is equal to x ispresent in the collection
Tape for a Turing Machine (Doubly-linked List)”.(I USE ECLIPSE & RUN CHECK ONLINE CONSOLE)A class named Tape to represent Turing machine tapes. The class should have an instance variable of type Cell that points to the current cell with the method: public Cell getCurrentCell() -- returns the pointer that points to the current cell. public char getContent() -- returns the char from the current cell. public void setContent(char ch) -- changes the char in the current cell to the specified value. Don't forget the Javadoc comments. IT WOULD HAVE A PUBLIC CLASS public void moveLeft() -- moves the current cell one position to the left along the tape. Note that if the current cell is the leftmost cell that exists, then a new cell must be created and added to the tape at the left of the current cell, and then the current cell pointer can be moved to point to the new cell. The content of the new cell should be a blank space. (Remember that the Turing machine's tape is conceptually…
Excercise: Listed next is the skeleton for a class named City. Each city has a name and temperature: public class City { private String cityName; private int temperature; } Flesh out the class with appropriate accessors, constructors, and mutators. Next, modify the class so that it implements the Comparable interface. The order between instances of the City class depends on the temperature. Test your class by creating an array of sample cities and sort them in an ascending order using Arrays.sort Notes: The language used for this question is Java. So far, this is the City class after fleshing it out: public class City implements Comparable<City> {private String cityName;private double temperature; public City() {} public City(String cityName, double temperature) {this.cityName = cityName;this.temperature = temperature;} public String getCityName() {return cityName;} public double getTemperature() {return temperature;} public void setName(String cityName)…
The following is the specification for the constructor of a EmailFolder class: /*** Creates a new EmailFolder with the given label** @precondition label != null AND !label.isEmpty()* @postcondition getLabel()==label*/public EmailFolder(String label) Assume the variable folders is an array list of EmailFolder objects. Write code that gets the tenth item in the list, assigning it to an appropriate variable. (java)
use the design pattern for collecting objects. We are going to model a Orchard with trees. An Orchard uses an ArrayList to keep track of Tree objects. You will write both a Orchard class and a Tree class. A Tree has a type and a height. Provide a constructor that takes type and height, in that order. Provide getters and setters for the instance variables. This is the design pattern for managing properties of objects. An Orchard has a constructor that takes no parameters. Remember it must initialize the instance variable. It also has methods ○ add() Adds the specified Tree to the Orchard ○ tallest() Gets the type of the tallest Tree in the Orchard or null if the Orchard is empty. Initialize the tallest with the first element. ○ contains() determines if a Tree of the given type is in the Orchard. Returns true if a Tree of the given type is in the Orchard. Otherwise false. ○ treeList() gets an ArrayList<String> containing the types of all…
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…
