Java假定要为某个公司编写雇员工资支付程序，这个公司有各种类型的雇员（Employee），不同类型的雇员按不同的方式支付工资（都是整数）： （1）经理（Manager）——每月获得一份固定的工资 （2）销售人员（Salesman）——在基本工资的基础上每月还有销售提成 （3）一般工人（Worker）——则按他每月工作的天数计算工资 在Employee中提供函数getSalary()计算每个雇员一个月的工资，并在子类中重写。 在main函数中构造Employee的三个变量，分别指向Manager、Salesman、Worker的对象，调用getSalary函数，输出三个对象的工资 输入格式: 经理的月工资 销售人员的基本工资 销售人员的提成 工人的工作天数 工人每天的工资 输出格式: 经理的工资 销售人员的工资 工人的工资 输入样例: 在这里给出一组输入。例如： 12000 3000 5000 22 200 输出样例: 在这里给出相应的输出。例如： 12000 8000

以下是Java实现代码：

import java.util.Scanner;

abstract class Employee {
    double salary;

    public abstract double getSalary();
}

class Manager extends Employee {
    double fixedSalary;

    public Manager(double fixedSalary) {
        this.fixedSalary = fixedSalary;
    }

    public double getSalary() {
        salary = fixedSalary;
        return salary;
    }
}

class Salesman extends Employee {
    double baseSalary;
    double commission;

    public Salesman(double baseSalary, double commission) {
        this.baseSalary = baseSalary;
        this.commission = commission;
    }

    public double getSalary() {
        salary = baseSalary + commission;
        return salary;
    }
}

class Worker extends Employee {
    int workDays;
    double dailySalary;

    public Worker(int workDays, double dailySalary) {
        this.workDays = workDays;
        this.dailySalary = dailySalary;
    }

    public double getSalary() {
        salary = workDays * dailySalary;
        return salary;
    }
}

public class Main {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        double fixedSalary = scanner.nextDouble();
        double baseSalary = scanner.nextDouble();
        double commission = scanner.nextDouble();
        int workDays = scanner.nextInt();
        double dailySalary = scanner.nextDouble();

        Employee manager = new Manager(fixedSalary);
        Employee salesman = new Salesman(baseSalary, commission);
        Employee worker = new Worker(workDays, dailySalary);

        System.out.println((int)manager.getSalary() + " " + (int)salesman.getSalary() + " " + (int)worker.getSalary());
    }
}
