用java编写一个程序：某个公司有3不同的雇员，分为A、B、C3个级别。。

Question

某个公司有3不同的雇员，分为A、B、C3个级别。公司总的雇员数目因月份的不同可能发生
变化，各个级别的人数每个月也可能发生变化。每个级别的月薪是互不相同的。编写一个程序
计算公司一个月需要支付的全部薪水。
要求有一个abstract类，类名为Employee。Employee的子类有AgradeEmployee、BgradeEmployee
CgradeEmployee。Employee类中有一个abstract方法，子类重写父类方法，给出各自的月薪水数。
编写一个Company类，该类用Employee数组作为成员，该数组元素可以是三个子类的上转型对象。
Company类提供计算月薪总和的方法，使得程序能输出Company对象需要支付的月薪总额。

class BgradeEmployee extends Employee{
private int theMoneyOfB;
public int theMoney(){
return theMoneyOfB;

}
}
class CgradeEmployee extends Employee{
private int theMoneyOfC;
public int theMoney(){
return theMoneyOfC;

}
}
class Company{
private int theNum;
Employee[] em=new Employee[theNum];
public void init(int i,Employee e){
em[i]=e;
}
public int sum(){
int sum=0;
for(int i=0;i<theNum;i++){
