适配器模式，完整代码，运行结果截图

题目：

有一个类(adaptee)实现了数学中的幂次运算，方法中需要传入两个参数，一个是基数base，另外一个是幂次exp。现在客户端需要一个求得一个数的平方的函数接口(target)，传入一个数，得到它的平方值。为了复用已经存在的类adaptee，适用Adapter来适配adaptee,adapter实现了target接口。 -Adapter mode, the complete code, the results capture Title: A Class (adaptee) to achieve a power of mathematics in the operation, the method requires two arguments, one is the base base, the other is a power exp. Now the client needs to obtain a square of a function Interface (target), pass a number, get it squared value. In order to reuse existing classes adaptee, for Adapter to fit adaptee, adapter implements the target interface.
