Java 多态的薪酬计算的练习

一个简单的 Java 多态的薪酬计算，主要练习面向对象编程的函数方法，

public class SalaryManage {
    public static void main(String[] args) {
        Programmer p01 = new Programmer(5000,3000);
        Salesman s01 = new Salesman(5000,20000);
        CalculateSalaryManage c01 = new CalculateSalaryManage();
        System.out.printf("程序员工资：%.2fn",c01.get_total_salary(p01));
        System.out.printf("销售员工资：%.2fn",c01.get_total_salary(s01));
    }
}

class CalculateSalaryManage{
    // 通过父类函数控制程序
    public double get_total_salary(Employee emp){
        return emp.calculateSalary();
    }
}

// 创建员工父类
class Employee{
    // 薪酬计算方法
    public  double calculateSalary(){
        return 0;
    }
}

//以上为构造部分
//------------------------------------------//
// 以下为添加子类

// 创建程序员子类，程序员薪水由基本工资和分红组成
class Programmer extends Employee{
    // 定义程序员工资变量
    private double baseSalary;
    private double bonus;
    // 初始化程序员对象
    public Programmer(double baseSalary,double Bonus){
       baseSalary = baseSalary;
       bonus = Bonus;
    }
    // 计算工资方法
    public  double calculateSalary(){
        double salary = baseSalary + bonus;
        return  salary;
    }
}

// 创建销售员子类，销售员薪水由基本工资和销售提成组成
class Salesman extends Employee{
    // 定义销售员工资变量
    private double baseSalary;
    private double deduct;
    // 初始化销售员对象
    public Salesman (double baseSalary,double Deduct){
        baseSalary = baseSalary;
        deduct = Deduct;
    }
    // 计算工资方法
    public  double calculateSalary(){
        double salary = baseSalary + deduct*0.05;
        return  salary;
    }
}
//............后面 添加其他类
