- c# programMake a class called Employees, with attributes Name, Gender, Experience, Salary and ID.Make a delegate called EligiblePromo. This delegate takes an employees object as a parameter and returns a boolean value indication whether or not the employee should be promoted.Make a PromoteEmployee() method that takes an arraylist of Employees and delegate of type EligiblePromo as parametersNB: PromoteEmployee() methos loops through each Employees object and passes it to the delegate(25)Java Program The assignment requires two classes. Put all classes in the same package. Class Employee Attributes (all private): id: String lastName: String firstName: String salary: int Methods: Parameterized constructor for initializing a new Employee instance Getters for all attributes toString method to display an Employee's attributes (See output of executable below) Executable Class Create an array of at least eight Employee objects. Be sure to use many with identical last names, but don't order them by name in the array. Create an ArrayList from the array. Sort the ArrayList first by last name and then by first name.

Constructor PassengerList () populates the list pnrList as given in the template code. -Method public PassengerInfo get PassengerInfo (String) should take a PNR number as argument, check if the PNR number is valid, and if yes, then return a valid Passenger Info object that has the name of the passenger. For ease of implementation, we assume that the valid PNR numbers are 1 to 3. An inner private class PassengerInfo Name of a passenger as an instance variable - This class implements interface IPassenger Info, which enables its object to be accessible from outside the class PassengerList. - Constructor PassengerInfo (String) assigns the name of the passenger to the instance variable of class Passenger Info whose PNR number is given. If the PNR number is 1, then the name should be passenger i, where the valid PNR numbers are for 1 ranging from 1 to 3.
