Implement the following tasks by using concepts of object-oriented programming (Java). i. Create a generic class with a type parameter that simulates drawing an item at random out of a box. This class could be used for simulating a random drawing. For example, the box might contain Strings representing names written on a slip of paper, or the box might contain Integers representing a random drawing for a lottery based on numeric lottery picks. Create an add method that allows the user of the class to add an object of the specified type along with an isEmpty method that determines whether or not the box is empty. Finally, your class should have a drawItem method that randomly selects an object from the box and returns it. If the user attempts to drawn an item out of an empty box, return null. Write a main method that tests your class.ii. The following is a short snippet of code that simulates rolling a 6-sided dice 100 times. There is an equal chance of rolling any digit from 1 to…

In c++ ( without empty constructor)Create a lecturer class with member-data name (name) and department (department). For the Lecturer class, write constructors, get & set methods, and the toString () method, which returns the textual description of the object. Write a Lecture class with data member:- subject (discipline)- weekday (day of the week when it takes place)- hour (start time, integer)- online (boolean value, whether remote or not)- lecturer (object of class Lecturer)For the Lecture class, write:- constructors- get & set methods- method isItMorning (), returning a Boolean value, the result of checking whether the lecture starts at 7-11- give a new implementation of the toString () method so that it returns the text description of the Lecture objectIn the test function main ()1. Create objects of both classes and illustrate the use of all possible methods for them.2. Create an array of Lecture objects and display it on the screen and in a file.
