Write code that creates an ArrayList that can hold String objects. Add the names of three cars to the ArrayList, and then display the contents of the ArrayList.
Library class:
Fields: books as arraylist to store all the books available in the library
B3
B1
B2
В4
B5
Constructor:
Library()
}
: No parameterized constructor to create the books object
Methods:
1. addBook(Book bookobj): to add a new book to the arraylist; send the book object as a
parameter to this method.
2. searchBook(String name): search a book by a given name in the arraylist. if exits print
bookX found; otherwise print not found!!!
3. RemoveBook(String name): to delete a book object from arraylist by a given name:
Hint: you need to use iterator class and remove method.
Book class:
Fileds: bookld, bookname.
Constructor: two parameterized constructor that accepts name
a parameter
Book(int ID, String name)
.....
Methods:
1. Accessor method to return the name of the book
2. Mutator method to change the id of the book.
Use this Main method: in your program:
public static void main(String args[])
{
Library lib=new Library();
lib.addBook(new Book("b1"));
lib.addBook(new Book("b2"));…
Arrays: create an array of a given type and populate its values. Use of for loop to traverse through an array to do the following : to print the elements one by one, to search the array for a given value.
ArrayList: create an ArrayList containing elements of a given type . Use some of the common ArrayList methods to manipulate contents of the ArrayList. Write methods that will take an ArrayList as its parameter/argument ; and/or return an ArrayList reference variable as its return type.
Searching for an object in an Array: Loop through the ArrayList to extract each object and to check if this object’s attribute has a given value.
Explain how and why interfaces are used in Java Collection Framework.
Explain the major differences between a Stack and a Queue. Be able to use stack and queue methods.

Task Check List ONLY "for" loops should be used within the data structure class. The names of identifiers MUST match the names listed in the description below. data fields: The fields to declare have private accessibility. size : stores the number of occupied locations in internal array, and is of type int. data : is a reference variable for the internal array and is of type E[ ]. constant: Use to describe defaults. DEFAULT_CAPACITY is a constant that holds a default capacity of ten (10) for the underlying array, is of type int , public accessibility and modified to static. constructors: The overloaded constructors will initialize the data fields size and data.

- in C#, Visual Basic Write an app for Boston Airlines that allows a customer to reserve a seat on the airline’s only plane (capacity: 10 seats). Radio buttons should allow the choice between First Class and Economy. The app should then assign a seat in the first-class section (seats 1–5) or the economy section (seats 6–10). Use a one-dimensional array of type bool to represent the seating chart of the plane. Initialize all the elements of the array to false to indicate that all the seats are empty. As each seat is assigned, set the corresponding element of the array to true to indicate that the seat is no longer available. Your app should never assign a seat that has already been assigned. When the economy section is full, your app should ask the person if it is acceptable to be placed in the first-class section (and vice versa). If yes, make the appropriate seat assignment. If no, display the message “Next flight leaves in 3 hours."arrow_forwardcontinue from first question, Client class:The client program will allow entry of these data for several different student into an ArrayList and then perform some analysis and queries.Your client class (program) will provide the user with a menu to perform the following operations.

For the csv file, your first item can be U or G to differentiate whether the entry is creating a UndergraduateStudent object, or a GraduateStudent object. You can then decide how you want other data to be listed in the csv file. You should specify clearly in your documentation the data format of the CSV files used in this assignment.1.
