Design a class Bank that contains a number of bank accounts. Each account has an account number and current balance. Add an accountNumber field to the BankAccount class. Store the bank accounts in array list. Write a readFile method of the Bank class for reading a file with the format accountNumber1, balancel accountNumber2, balance2 Write a readAndPerformTransactions method of the Bank class for reading a file that describes t transactions done by different bank accounts and perform these transactions. For example, 1234456742 withdraw 375 8686349535 deposit deposit 850 1234456742 150

• 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.
GuitarString.java Create a data type to model a vibrating guitar string. Write a class named GuitarString that implements the following API: public class GuitarString // Creates a guitar string of the specified frequency, // using a sampling rate of 44,100. public GuitarString(double frequency) // Creates a guitar string whose length and initial values // are given by the specified array. public GuitarString(double[] init) // Returns the number of samples in the ring buffer. public int length() // Plucks this guitar string by replacing the ring buffer with white noise. public void pluck() // Advances the Karplus-Strong simulation one time step. public void tic() // Returns the current sample. public double sample() // Tests this class by directly calling both constructors // and all instance methods. public static void main(String[] args)
Create a class called Planet. A planet's state is it's name and a list (array) of moons that it has. You can assume there is a Moon class that a single constructor that takes it's name as input (a String). Add three constructors to your Planet class: Planet(String planetName) (planet has no moons)Planet(String planetName, String moonName) (planet has one moon)Planet(String planetName, Moon[] moons) (planet has arbitrary number of moons). Be sure to use constructor chaining. Question: When creating a planet object, what is the minimum number of constructors that are called (in total, either explicitly by you or by the JVM)? What is the maximum number of constructors that might be called (in total, either explicitly by you or by the JVM)? Give an example for each.

Consider an example of declaring the examination result. Design three classes:STUDENT , EXAM and RESULT. The STUDENT class has data members such as those representing roll number, name etc. Create the class EXAM by inheriting the STUDENT class. The EXAM class adds data members representing the marks scored in six subjects(out of 100). Derive the RESULT from the EXAM class and it has its own data members such as total marks. Write an interactive program that show students details along with their percentage.
Write a C#program that uses a class called ClassRegistration as outlined below: The ClassRegistration class is responsible for keeping track of the student id numbers for students that register for a particular class. Each class has a maximum number of students that it can accommodate. Responsibilities of the ClassRegistration class: It is responsible for storing the student id numbers for a particular class (in an array of integers) It is responsible for adding new student id numbers to this list (returns boolean) It is responsible for checking if a student id is in the list (returns a boolean) It is responsible for getting a list of all students in the class (returns a string). It is responsible for returning the number of students registered for the class (returns an integer) It is responsible for returning the maximum number of students the class is allowed (returns an integer) It is responsible for returning the name of the class. (returns a string) ClassRegistration -…

A programmer is designing a program to catalog all books in a library. He plans to have a Book class that stores features of each book: author, title, isOnShelf, and so on, with operations like getAuthor, getTitle, getShelf Info, and set Shelf Info. Another class, LibraryList, will store an array of Book objects. The LibraryList class will include operations such as listAll Books, addBook, removeBook, and searchForBook. The programmer plans to implement and test the Book class first, before implementing the LibraryList class. The program- mer's plan to write the Book class first is an example of (A) top-down development. (B) bottom-up development. (C) procedural abstraction. (D) information hiding. (E) a driver program.
