java简单应用—信号报告

题目内容：

无线电台的RS制信号报告是由三两个部分组成的：

R(Readability) 信号可辨度即清晰度.

S(Strength)    信号强度即大小.

其中R位于报告第一位，共分5级，用1—5数字表示.

1---Unreadable

2---Barely readable, occasional words distinguishable

3---Readable with considerable difficulty

4---Readable with practically no difficulty

5---Perfectly readable

报告第二位是S，共分九个级别，用1—9中的一位数字表示

1---Faint signals, barely perceptible

2---Very weak signals

3---Weak signals

4---Fair signals

5---Fairly good signals

6---Good signals

7---Moderately strong signals

8---Strong signals

9---Extremely strong signals

现在，你的程序要读入一个信号报告的数字，然后输出对应的含义。如读到59，则输出：

Extremely strong signals, perfectly readable.

输入格式:

一个整数，信号报告。整数的十位部分表示可辨度，个位部分表示强度。输入的整数范围是[11,59]内有效的数字，这个范围外的数字不可能出现在测试数据中。

输出格式：

一句话，表示这个信号报告的意义。按照题目中的文字，先输出表示强度的文字，跟上逗号和空格，然后是表示可辨度的文字，跟上句号。注意可辨度的句子的第一个字母是小写的。注意这里的标点符号都是英文的。

输入样例：

33

输出样例：

Weak signals, readable with considerable difficulty.

时间限制：500ms内存限制：32000kb

本来是字符串的简单题目，但是我却各种编译失败，于是乎，便用了类的继承来做，代码写着很累，纯属练习类的继承
