职工类（Employee)

要求：包含name、age和salary（月薪），并且完成构造方法、相应的getter、setter方法以及获得收入方法（getIncome）。 注：职工的收入就是工资。

经理类（Manager）

要求：包含name、age和salary（月薪）、bonus（奖金），完成构造方法、相应的getter、setter方法以及获得收入方法（getIncome）。 注：经理的收入=工资+奖金。

构造Employee类和Manager类方法、属性

Employee类

class Employee{
          
   
	protected String name;
	protected int age;
	protected double salary;//月薪
	public Employee(String name,int age,double salary) {
          
   
		this.setName(name);
		this.setAge(age);
		this.setSalary(salary);
	}
	public Employee(){
          
   
		this(null,0,0);
	}
	public static void main(String[] args) {
          
   
		// TODO 自动生成的方法存根
	}
	public String getName() {
          
   
		return name;
	}
	public void setName(String name) {
          
   
		this.name = name;
	}
	public int getAge() {
          
   
		return age;
	}
	public void setAge(int age) {
          
   
		this.age = age;
	}
	public double getSalary() {
          
   
		return salary;
	}
	public void setSalary(double salary) {
          
   
		this.salary = salary;
	}
	public double getIncome() {
          
   
		// TODO 自动生成的方法存根
		return salary;
	}
}

Manager类

class Manager extends Employee{
          
   
	private double bonus;
	public void setBonus(double bonus) {
          
   
		this.bonus=bonus;
	}
	Manager(String name,int age,double salary,double bonus){
          
   
		super(name,age,salary);
		this.bonus=bonus;
	}
	Manager(){
          
   
		super();
		bonus=0;
	}
	public double getIncome() {
          
   
		return super.getIncome()+bonus;
	}
}
class CountPay{
          
   
	private static double pay;
	public static void doCount(Employee e) {
          
   
		setPay(getPay() + e.getIncome());
	}
	public static void doCount(Manager m) {
          
   
		setPay(getPay() + m.getIncome());
	}
	public static double getPay() {
          
   
		return pay;
	}
	public static void setPay(double pay) {
          
   
		CountPay.pay = pay;
	}
}

主函数——各种方式调用的输出形式

main主函数

public static void main(String[] args) {

		System.out.println("=====第1种形式=====");

			System.out.println(employees[i]);
