The main question is the entire page labeled Program #2 and the little screenshot is for extra steps. The program has to be written in Java, please provide comments for explanation. 2. Each student at Middlesex County College takes a different number of courses, so theregistrar has decided to use linear linked lists to store each student's class scheduleand an array to represent the entire student body.A portion of this data structure is shown below:ID link$||1||1123422357Sec cr→ [CSC162|1|33> HISI 1224CSC236/4/3These data show that the first student (ID: 1111) is taking section 1 of CSC162 for 3credits and section 2 of HIS101 for 4 credits; the second student is not enrolled; thethird student is enrolled in CSC236 section 4 for 3 credits.Write a class for this data structure. Provide methods for creating the original array,inserting a student's initial class schedule, adding a course, and dropping a course. Includea menu-driven program that uses the class.7 Program #21.

3. The interface Range is defined below:public interface Range{ void setLimits(int x, int y); int getNumber();} Implementations of Range should exhibit the following behaviour:• The setLimits method should store its parameter values somewhere to serve as the lower and upper limits of the range appropriately.• A call to getValue should return an integer that is always greater than or equal to the lower limit and less than or equal to the upper limit.The class RandomInteger is an implementation of the interface Range. It also has the following features:• It has two fields of int type, low and high, to record the lower and upper limits of the range, respectively.• It has single constructor method that takes two integers and stores them in the appropriate fields. Note: You should make use of the setLimits method.• A call to the method getNumber should return a random number that is always within the range, i.e. greater than or equal to the lower limit and less than or equal to the upper…

Add CompareTo() method for the data Name. Write a class named Manager which inherits the Employee class. Add an instance variable, named department, of type String. Add a constructor in the subclass class with arguments name, salary, department and a toString() method that prints the manager’s name, department, and salary [Hint: Add a toString( ) method in the super class as well] Create 3 objects of Manager with following arguments 1.

1. Create a Student class that implements the Person interface. As well as storing the students name and email, also store their course grade (e.g A, B, C) in a member variable. The grade should be accessible via a getGrade method. For the implementation of getDescription return a message along the lines of “A C grade student”, substituting the students actual grade.2. Create a Lecturer class that implements the Person interface. This class should also store the subject that the lecturer teaches. Add a getSubject method, and implement getDescription so that it returns a suitable message, e.g. “Teaches Biology”.3. Create a third class, Employee that implements the interface. This should also store the name of the department the Employee works in (available via getDepartment). Again, getDescription should return a suitable message.
1). Develop a class named Department with two data members: name and size. The name cantake values such as "Finance", "Human Resources". size is for how many people work in thedepartment; You should provide all constructors, all get/set methods, and the toString method;2). Develop a class called Company which should have at least four data members: name,address, totalNumberOfEmployees, and departments (of type Department; an array). The relationbetween Company and Department is composition. The total number of employees is the sum ofthe sizes of all departments. You should provide all constructors, especially the constructor thatreceives departments as an initial value, all get/set methods, and the toString method;3).

One parameter sets the string, the other three parameters are used as arguments for a parent constructor call. d) Admin objects have an instance getInformation() method with a void return and an Employee object parameter. The method will request the calling Admin’s password and check user input. If input matches the password, the method will display the information of the Employee parameter Please use ***C Sharp** Language to answer the code

Create an abstract NewspaperSubscription class with fields for the subscriber name, address, and rate. Include get and set methods for the name field and get methods for the address and subscription rate; the setAddress() method is abstract. Create two subclasses named PhysicalNewspaperSubscription and OnlineNewspaperSubscription. The parameter for the setAddress() method of the PhysicalNewspaperSubscription class must contain at least one digit; otherwise, an error message is displayed and the subscription rate is set to 0. If the address is valid, the subscription rate is assigned $15. The parameter for the setAddress() method of the OnlineNewspaperSubscription class must contain an at sign (@) or an error message is displayed. If the address is valid, the subscription rate is assigned $9. Finally, write an application that declares several objects of both subscription subtypes and displays their data fields
