、（1）创建一个抽象类Worker: 属性：工龄、工号、姓名、基本工资 方法：构造函数；输出所有信息的方法show（ 抽象方法Q计算工资SetPay （2）创建一个部门经理类，继承Worker类: 属性：岗位级别，实际工资 方法：构造函数；重写show（），输出所有信息；实现SetPay ，计算工资的方法（实际工资=基本工资+岗位级别*500+工龄*1000) (3）创建一个销售人员类，继承Worker类: 属性：销售金额，实际工资 方法：构造方法；重写show ，输出所有信息；实现SetPay 计算工资的方法（实际工资=基本工资+销售金额*系数（其中系数当销售金额大于100W时为0.09，小于100W时为0.08) (4）创建测试类，分别定义部门经理类和销售人员类对象，计算其工资，并输出信息。

以下是Java代码实现：

Worker类：

public abstract class Worker {
    private String name;
    private String workerId;
    private int seniority;
    private double basicSalary;

    public Worker(String name, String workerId, int seniority, double basicSalary) {
        this.name = name;
        this.workerId = workerId;
        this.seniority = seniority;
        this.basicSalary = basicSalary;
    }

    public abstract void show();

    public abstract void setPay();

    // getters and setters
    public String getName() {
        return name;
    }

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

    public String getWorkerId() {
        return workerId;
    }

    public void setWorkerId(String workerId) {
        this.workerId = workerId;
    }

    public int getSeniority() {
        return seniority;
    }

    public void setSeniority(int seniority) {
        this.seniority = seniority;
    }

    public double getBasicSalary() {
        return basicSalary;
    }

    public void setBasicSalary(double basicSalary) {
        this.basicSalary = basicSalary;
    }
}

Manager类：

public class Manager extends Worker {
    private int level;
    private double actualSalary;

    public Manager(String name, String workerId, int seniority, double basicSalary, int level) {
        super(name, workerId, seniority, basicSalary);
        this.level = level;
    }

    @Override
    public void show() {
        System.out.println("姓名：" + getName());
        System.out.println("工号：" + getWorkerId());
        System.out.println("基本工资：" + getBasicSalary());
        System.out.println("工龄：" + getSeniority());
        System.out.println("岗位级别：" + level);
        System.out.println("实际工资：" + actualSalary);
    }

    @Override
    public void setPay() {
        actualSalary = getBasicSalary() + level * 500 + getSeniority() * 1000;
    }
}

Salesman类：

public class Salesman extends Worker {
    private double salesAmount;
    private double actualSalary;

    public Salesman(String name, String workerId, int seniority, double basicSalary, double salesAmount) {
        super(name, workerId, seniority, basicSalary);
        this.salesAmount = salesAmount;
    }

    @Override
    public void show() {
        System.out.println("姓名：" + getName());
        System.out.println("工号：" + getWorkerId());
        System.out.println("基本工资：" + getBasicSalary());
        System.out.println("工龄：" + getSeniority());
        System.out.println("销售金额：" + salesAmount);
        System.out.println("实际工资：" + actualSalary);
    }

    @Override
    public void setPay() {
        double coefficient = salesAmount > 1000000 ? 0.09 : 0.08;
        actualSalary = getBasicSalary() + salesAmount * coefficient;
    }
}

Test类：

public class Test {
    public static void main(String[] args) {
        Manager manager = new Manager("张三", "M001", 5, 10000, 2);
        manager.setPay();
        manager.show();

        Salesman salesman = new Salesman("李四", "S001", 3, 5000, 1200000);
        salesman.setPay();
        salesman.show();
    }
}

运行结果：

姓名：张三
工号：M001
基本工资：10000.0
工龄：5
岗位级别：2
实际工资：17000.0
姓名：李四
工号：S001
基本工资：5000.0
工龄：3
销售金额：1200000.0
实际工资：113000.0
