Answer 1

public class Employee {
    private String name;
    private double salary;
    private int leaveDays;
    private double workHours;


    public Employee(String name) {
        this.name = name;
        salary = 50000;
        leaveDays = 15;
        workHours = 35;
    }

    public void setName(String name) {
        this.name = name;
    }

    protected String getName() {
        return name;
    }

    public double getSalary() {
        return salary;
    }

    public void setSalary(double salary) {
        this.salary = salary;
    }

    public int getLeaveDays() {
        return leaveDays;
    }

    public void setLeaveDays(int leaveDays) {
        this.leaveDays = leaveDays;
    }

    public double getWorkHours() {
        return workHours;
    }

    public void setWorkHours(double workHours) {
        this.workHours = workHours;
    }

    @Override
    public String toString() {
        return "Employee{" +

public class Manager extends Employee {
    public Manager(String name) {
        super(name);
        setSalary(getSalary() + 20000);
        setLeaveDays(getLeaveDays() + 3);
    }
}

public class Secretary extends Employee {
    public Secretary(String name) {
        super(name);
        setWorkHours(40);
    }

import java.util.Random;

public class Main {

        double totalSalary = 0;
        for (int i = 0; i < names.length; i++) {
            employees[i] = new Random().nextBoolean() ?
                    (new Random().nextBoolean() ? new Manager(names[i]) : new Employee(names[i]))
                    : new Secretary(names[i]);
            totalSalary += employees[i].getSalary();
        }
        for (int i = 0; i < names.length; i++) {
            System.out.println(employees[i]);
        }
        System.out.println("Average salary: " + totalSalary / names.length);
        double salaryPerDay;
        for (int i = 0; i < names.length; i++) {
            salaryPerDay = employees[i].getSalary() / 365;
            System.out.println(employees[i].getName() + " leave cost: " + employees[i].getLeaveDays() * salaryPerDay);
