True or false: The default constructor is the only constructor that may be called for objects in an array of objects.
10. Lottery Application
Write a Lottery class that simulates a lottery. The class should have an array of five integers
named lotteryNumbers. The constructor should use the Random class (from the Java API) to
generate a random number in the range of 0 through 9 for each element in the array. The
class should also have a method that accepts an array of five integers that represent a per-
son's lottery picks. The method is to compare the corresponding elements in the two arrays
and return the number of digits that match. For example, the following shows the
lotteryNumbers array and the user's array with sample numbers stored in each. There are
two matching digits (elements 2 and 4).
lotteryNumbers array:
User's array:
7 4
4
2
1 3
7 3
In addition, the class should have a method that returns a copy of the lotteryNumbers array.
Demonstrate the class in a program that asks the user to enter five numbers. The program
should display the number of digits that match the randomly generated…
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"));…

Then write a program that creates at least five PhoneBookEntry objects and stores them in an ArrayList. Use a loop to display the contents of each object in the ArrayList.arrow_forwardTrue/ False 1- Class objects can be defined prior to the class declaration. 2- You must use the private access specification for all data members of a class. 3- If an array is partially initialized, the uninitialized elements will be set to zero. 4- A vector object automatically expands in size to accommodate the items stored in it. 5- With pointer variables, you can access but not modify data in other variables. 6- Assuming myValues is an array of int values and index is an int variable, both of the following statements do the same thing. 1. cout header file. 15- To solve a problem recursively, you must identify at least one case in which the problem can be solved without recursion.arrow_forward1. Square Roots Create a class with a method that, given an integer, returns an array of double-precision floating point numbers (known in Java as double), each of which is a square root of a number between 2 and the parameter to the method. For example, if the parameter is 5, the method should return an array of 4 doubles, with approximate values 1.4142135623, 1.7320508075, 2.0, and 2.2360679774. Your method should check the validity of the parameter, and take appropriate action if the parameter is invalid. 2.

- Homework - identical arrays for one-dimensional: Write a test program which prompts a user to enter the size of two arrays as well as to fill their elements. After that, the program checks the same contents of the elements of the two arrays. If these arrays are equal, the program displays message which is "The two arrays are identical". If not equal, displaying "The two arrays are not identical". Write an equals method that reads two arrays and displays these messages above.arrow_forwardJavaDriver Program Write a driver program that contains a main method and two other methods. Create an Array of Objects In the main method, create an array of Food that holds at least two foods and at least two vegetables. You can decide what data to use. Method: Print Write a method that prints the text representation of the foods in the array in reverse order (meaning from the end of the array to the beginning). Invoke this method from main. Method: Highest Sugar Food Write a method that takes an array of Food objects and finds the Food that has the most sugar. Note that the method is finding the Food, not the grams of sugar. Hint: in looping to find the food, keep track of both the current highest index and value.
