（1）写一个final参数类M，包括比较次数、交换次数、探测次数属性，并重写构造器和toString方法。

（2）写一个抽象类A，其中包括要排序的数据。提供三个final方法，分别完成比较、探测、交换操作的同时，正确改变私有的M类对象成员的相关属性。并提供一个虚方法doSort,同时提供一个final方法sort（先设置M对象初值，然后调用doSort方法，返回M对象引用）

（3）写三个采用不同方法排序的A类的派生类A1,A2,A3

（4）写一个测试类作为主类，分别生成A1,A2,A3的对象并调用sort方法，显示三个方法在排序时候的性能参数。

（5）谈谈这种类设计的合理性以及可以改进之处。

-1) write a final parameters, including comparison of M times, The Times, the exchange properties, both times detection write constructors and toString method.

(2) write an abstract class A, including to sort of data. Provide three final method respectively, complete comparison, detection and exchange operations at the same time, the correct change private M class object of members related attributes. And provide a virtual method doSort, at the same time provide a final method sort (first set, and then the initial value object M call doSort method, return to M object reference)

(3) write three by different methods of sort of A kind of derived class A1, A2, A3

(4) write a test class as the main class respectively, A1, A2, A3 generated the object and call sort method, shows three methods in order of time performance parameters.

(5) talk about this kind of the rationality of the design of and can improvements.
