• 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 get PassengerInfo (String) should take a PNR number as argument, check
if the PNR number is valid, and if yes, then return a valid Passenger Info 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 PassengerInfo
Name of a passenger as an instance variable
- This class implements interface IPassenger Info, 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 Passenger Info whose PNR number is given. If the PNR number is 1, then the name should be passenger i,
where the valid PNR numbers are for 1 ranging from 1 to 3.
A class Student can have three member variables: name, age, and an array of grades of two exams marks [5]. The grades can be integers (0-100), doubles (0.0-100.00) and characters (A-F, where F denotes grades less than 50). Write a class template to accommodate all five types of grades. The class template must have two constructors (no-arg constructor, and aconstructor that takes 7 parameters: name, age and grades of 5 exams). Write a c++ function to read an object from console, and another function to print the object to the console. Implement the class template by creating three objects with three different types (int, double and char) of grades, and printing the objects on the console.
Description:
Create a class named ComparableDog that extends Animal and implements Comparable interface.
Implement the compareTo method to compare the Dogs on the basis of age.
Write a test class to find the bigger age of two instances of ComparableDog Objects, and complement the ComparableDog class with the missing part.
1) The test program, the ComparableDog class, and its super class Animal are given as follows.
// Main method
public static void main(String[] args) {
// Create two comparable Dogs
ComparableDog dog1 = new ComparableDog(3);
ComparableDog dog2 = new ComparableDog(4);
System.out.println("Dog1:" + dog1);
System.out.println("Dog2:" + dog2);
if(dog1.compareTo(dog2) == 1)
System.out.println("Dog1 is older than Dog2");
else if(dog1.compareTo(dog2) == -1)
System.out.println("Dog1 is younger than Dog2");
else
System.out.println("Dog1 and Dog2 have the same age");

- Observer pattern The PhoneModel class stores a phone number as a list of digits, and the Keypad class has this method: public void simulateKeyPresses(int numKeyPresses)(0 that allows the user to enter digits one at a time then save each digit in the list. The Screen wants to respond to each key being entered. Make the model notify the observers whenever a new digit is entered for the phone number. The first observer prints the newest digit out to the screen The second observer prints "Now dialing 12345678901.." out to the screen (where the number is the number the model has). Only the Screen class can print to the screen The model must be decoupled from the Other classes.arrow_forwardComputer Science You are required to develop a small chatting application where two or more friends can communicate each other through messages.
