在程序中声明一个表示雇员的类Employee。在类Employee中声明两个成员变量，分别表示雇员的姓名和薪酬。声明类Employee构造方法，声明设置和获取成员变量值的成员方法。 声明一个部门经理类Manager，Manager继承自Employee。在Manager中增加表示部门经理奖金的成员变量。声明类Manager的构造方法，声明设置和获取成员变量值的成员方法。 在程序的主类PayrollApp中创建一个Manager类的对象，对其进行初始化，并且在控制台输出它的成员变量的值

以下是Java代码实现：

public class Employee {
    private String name;
    private double salary;

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

    public String getName() {
        return name;
    }

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

    public double getSalary() {
        return salary;
    }

    public void setSalary(double salary) {
        this.salary = salary;
    }
}

public class Manager extends Employee {
    private double bonus;

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

    public double getBonus() {
        return bonus;
    }

    public void setBonus(double bonus) {
        this.bonus = bonus;
    }
}

public class PayrollApp {
    public static void main(String[] args) {
        Manager manager = new Manager("Tom", 5000, 1000);
        System.out.println("Name: " + manager.getName());
        System.out.println("Salary: " + manager.getSalary());
        System.out.println("Bonus: " + manager.getBonus());
    }
}

输出结果为：

Name: Tom
Salary: 5000.0
Bonus: 1000.0
