- Solve this question according to the question requirements and using encapsulation, object array in Java object-oriented programming in java netbeans. Write a program that simulates inventory bins in a warehouse.Each bin holds a number of the same type of parts.The program should use a Class that keeps the following data:Description of the part kept in the binNumber of parts in the bin Then Create a Stock class which hold an array of 10 bins, which can store data as follows (This is an example to give you an idea):Part Description Number of Parts in the BinValve 10Bearing 5Bushing 15Coupling 21Flange 7Gear 5Gear Housing 5Vacuum Gripper 25Cable 18Rod 12 Provide Constructors, getters, setters and following methods:1. AddBin (Bin b), this add bins to the array.2. RemoveBin (String name), removes a Bin form array.3. AddParts: a function that increases a specific bin’s part count by a specified number.4. RemoveParts: a function that decreases a specific bin’s part count by a specified…create a driver program, CarTestDriver that uses a Garage object to store Cars. The Garage object is an instantiation of a Garage class that contains “parking”, an array of Car types. You must use a Car[] not an ArrayList<Car> for the “parking” in the garage. I suggest setting up the Car class with a default constructor that generates random values to create each new Car object. The rules for driving the cars from the garage are: The size of the garage is specified by the user. The user may only use cars from the garage A Car is removed from the Garage when a user retrieves a Car from the Garage. The Car is returned to the Garage, after it is driven if it does not run out of fuel. The user interacts with the Car object after the Car object is retrieved from the garage. The program should not fail due to a user selection. A car may only be refueled when the user selects the Car for use, prior to being removed from the Garage The user may select to drive any car that is currently…for c++ Write a program that allows two players to play the tick-tac-toe game. Your program must contain the class ticTacToe to implement a ticTacToe object. Include a 3-by-3 two-dimensional array, as a private member variable, to create the board. If needed, include additional member variables. Some of the operations on a ticTacToe object are printing the current board, getting a move, checking if a move is valid, and determining the winner after each move. Add additional operations as needed.
- in c++ . Create a class IntegerSet for which each object can hold integers in the range 0 through 100. A set is represented internally as an array of ones and zeros. Array element a[ i ] is 1 if integer i is in the set. Array element a[ j ] is 0 if integer j is not in the set. • The default constructor initializes a set to the so-called “empty set,” i.e., a set whose array representation contains all zeros. • Provide member functions for the common set operations. For example, provide a unionOfSets member function that creates a third set that is the settheoretic union of two existing sets (i.e., an element of the third set’s array is set to 1 if that element is 1 in either or both of the existing sets, and an element of the third set’s array is set to 0 if that element is 0 in each of the existingsets). Provide an intersectionOfSets member function which creates a third set which is the set theoretic intersection of two existing sets (i.e., an element of the third set’s array is set…Let B be a class with a constructor that can receive an int as its parameter. B doesn't have a user- provided default constructor. class B { public: B(int n) { cout <« n <« endl; }; }; How many times a constructor is called with the following definition of an array? (Hint: Try it in an IDE) B arr[4] {{0}, {1}, B{2}, 3}; O 2 O 4 O 1 None of these.Suppose that the bag class is efficiently implemented with a fixed array with a capacity of 4000, as in Chapter 3 of the class text. We execute these statements: bag b; b.insert(5); b.insert(4); b.insert(6); b.erase_one(5); Group of answer choices b.used is 2, b.data[0] is 4, b.data[1] is 6 b.used is 2, b.data[0] is 6, b.data[1] is 4 b.used is 3, b.data[0] is 4, b.data[1] is 6 b.used is 3, b.data[0] is 6, b.data[1] is 4
- Java programming I have to do the "Resize method" which I believe if the array is full, it should resize so there is space. Ill paste the code below: package circularQueue; /* * Design the class that would implement the interfaceiQueue. */ public class cirQueue <T> implements iQueue <T> { //Array of T objects private T[] Ar; //reference to array of objects //int size keeps track of how many elements in the queue int size = 0; //first the index to the head of the queue int first = -1; //last the index the last element of the queue int last = -1; public cirQueue() { Ar = (T[]) new Object[5]; size = 0; first = last = -1; } public int size() { return size; } public boolean empty() { return (size == 0); } private void resize() { //HW TODO } //inserts element e at the back of the queue public void insert(T e) { if(this.empty()) { first = last = 0; //insert e at indx 0; Ar[first] = e; size = 1; return; } if(size == Ar.length) { //resize HW complete this one.…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.Write a smart pointer class. A smart pointer is a data type, usually implemented with templates, that simulates a pointer while also providing automatic garbage collection. It automatically counts the number of references to a SmartPointer<?> object and frees the object of type T when the reference count hits zero.
