Java中类的继承及其应用（加强1）

1、假如我们在开发一个系统时需要对员工进行建模，【员工Employee】包含3个属性：姓名name、工号id以及工资salary；【经理Manager】也是员工，除了含有员工的属性外，另为还有一个奖金属性bonus。
请使用继承的思想设计出员工类和经理类，要求类中提供必要的方法进行属性访问，并能够一次性输出对象的基本信息。

public class Main {
    public static void main(String[] args) {
        Employee e1 = new Employee("Zhangsan",20202001,8800);
        Manager m1 =new Manager("Lisi",20203001,9800,12000);
        e1.show();
        m1.show();

    }

            this.name=name;
            this.ID=ID;
