-----------------运行结束-----------------------
[备注]：大哥，因为不是很理解上面的应用，假如需要计算的话，你可以自己修改一下代码算法。基本的架构都已经搭建了，采用构造类和承继方法进行，你把这几个文件都分开存放在一个文件夹下面就可以了。运行Text.java 这个文件。
这些都是自己写的，希望能给予你参考作用。
代码如下，说明几点：
1.共有6个文件，五个类和一个测试文件
2.有些类的命名可能打的不一样，比如掉了个ee之类的，不过很好看出来
3.为了利于实现，没有使用java自带的toString,而是自定义了个toStr.

这个题目说明
:
1
编写包含员工名称及工资属性的
超类
，并实现一个返回float/double类型的print()方法
这个的
构造器
我没实际写过，不知道继承的父类要不要全部包含子类构造器。你自己在实现子类时再来改吧
2
编写四个
Employee
的子类。
每个子类的构造器不能用默认无参构造器，必须使用有参的构造器
同时子类有各自的属性，比如
计件工
的数量，计时工的时间等等。
并重写print()方法，按要求的
逻辑
返回应得工资金额
大概就是这样。只是
具体实现逻辑题目没写。你的重写的print()方法逻辑可以简单点。大概一下就行
比如只返回每月工资，
计件的数量随便给个就是。
