Hints

super.pay() runs the parent's version of the method.

Solution explanation

Using super.pay() means a later change to Employee.pay() automatically reaches managers too.

import java.util.Scanner;

class Employee {
    final String name;
    final double salary;

    Employee(String name, double salary) {
        this.name = name;
        this.salary = salary;
    }

    double pay() {
        return salary;
    }
}

class Manager extends Employee {
    final double bonus;

    Manager(String name, double salary, double bonus) {
        super(name, salary);
        this.bonus = bonus;
    }

    @Override
    double pay() {
        return super.pay() + bonus;
    }
}

public class Main {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        int n = sc.nextInt();
        double total = 0;
        for (int i = 0; i < n; i++) {
            String kind = sc.next();
            String name = sc.next();
            double salary = sc.nextDouble();
            Employee e = kind.equals("M") ? new Manager(name, salary, sc.nextDouble()) : new Employee(name, salary);
            System.out.printf("%s %.2f%n", e.name, e.pay());
            total += e.pay();
        }
        System.out.printf("total %.2f%n", total);
    }
