编写一个Employee类，声明为抽象类，包含如下三个属性: name, id, salary.提供必要的构造器和抽象方法:work()。对于Manager类来说，他既是员工，还具有奖金(bonus)的属性。请使用继承的思想,设计CommonEmployee类和Manager类，要求类中提供必要的方法进行属性访问,实现work()，提示"经理/普通员工名字工作中.."

package HspAll.Abstract_;

abstract public class Employee {
private String name;
private int id;
private double salary;

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

//将work做成一个抽象方法
public abstract void work();
public String getName() {
    return name;
}

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

public int getId() {
    return id;
}

public void setId(int id) {
    this.id = id;
}

public double getSalary() {
    return salary;
}

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

}

==========
package HspAll.Abstract_;

public class Manager extends Employee{
private double bonus;
public Manager(String name, int id, double salary) {
super(name, id, salary);
}

public double getBonus() {
    return bonus;
}

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

public void work(){
    System.out.println("经理"+getName()+"正在工作中....");

}

}

ackage HspAll.Abstract_;

public class EmployCommon extends Employee {
public EmployCommon(String name, int id, double salary) {
super(name, id, salary);
}

@Override
public void work() {
    System.out.println("普通员工"+getName()+"正在工作中");

}

}

package HspAll.Abstract_;

public class Exercise {
public static void main(String[] args) {
Manager M1 = new Manager("jack",1234,20000);
M1.setBonus(90000);
M1.work();

}

}
