大家好，欢迎来到IT知识分享网。

————————~~~~

Cola公司的雇员分为以下若干类: (知识点:多态)[必做题]

4.1 ColaEmployee :这是所有员工总的父类,属性:员工的姓名,员工的生日月份。方法: getSalary(int month)根据参数月份来确定工资,如果该月员工过生日,则公司会额外奖励100元。

4.2 SalariedEmployee: ColaEmployee的子类,拿固定工资的员工。属性:且薪gramming Your Future果后作业

4.3 HourlyEmployee : ColaEmployee的子类,按小时拿工资的员工,每月工作超出160小时的部分按照1.5倍工资发放。属性:每小时的工资、每月工作的小时数

4.4 SalesEmployee : ColaEmployee的子类,销售人员,工资由月销售额和提成率决定。属性:月销售额、提成率

4.5定义一个类Company,在该类中写一个方法,调用该方法可以打印出某月某个员工的工资数额,写一个测试类TestCompany,在main方法,把若干各种类型的员工放在一个ColaEmployee数组里,并单元出数组中每个员工当月的T

利用接口实现动态的创建对象[选做题]
5.1 创建4个类：
•苹果
•香蕉
•葡萄
•园丁
5.2 在三种水果的构造方法中打印一句话.
•以苹果类为例
class apple{
　　public apple(){
　　　　System.out.println(―创建了一个苹果类的对象‖);
　　}
}
5.3 要求从控制台输入一个字符串，根据字符串的值来判断创建三种水果中哪个类的对象

        while(true) {
            System.out.println("请输入想要创造的水果");
            try {
