Hints

The first line of the Manager constructor is super(name, salary);

Only read the bonus when the type is M.

Solution explanation

An Employee[] array can hold managers too. Each object's own pay() is used.

import java.util.Scanner;

class Employee {
    String name;
    int salary;

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

    int pay() { return salary; }
}

class Manager extends Employee {
    int bonus;

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

    @Override
    int pay() { return salary + bonus; }
}

public class Main {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        int n = sc.nextInt();
        Employee[] staff = new Employee[n];
        for (int i = 0; i < n; i++) {
            String type = sc.next();
            String name = sc.next();
            int salary = sc.nextInt();
            staff[i] = type.equals("M") ? new Manager(name, salary, sc.nextInt()) : new Employee(name, salary);
        }
        int total = 0;
        for (Employee e : staff) {
            System.out.println(e.name + " earns " + e.pay());
            total += e.pay();
        }
        System.out.println("Total: " + total);
    }
