信号报告

信号报告（5分）

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

代码

import java.util.Scanner;

public class Main {

	public static void main(String[] args) {
		Scanner in = new Scanner(System.in);
		int P = in.nextInt();
		int S = P % 10;
		int R = (P - S)/10;
		String r,s;
		if (S == 1) {
			s = "Faint signals, barely perceptible";
			System.out.print(s+",");
		}else if(S == 2){
			s = "Very weak signals";
			System.out.print(s+",");
		}else if(S == 3){
			s = "Weak signals";
			System.out.print(s+",");
		}else if(S == 4){
			s = "Fair signals";
			System.out.print(s+",");
		}else if(S == 5){
			s = "Fairly good signals";
			System.out.print(s+",");
		}else if(S == 6){
			s = "Good signals";
			System.out.print(s+",");
		}else if(S == 7){
			s = "Moderately strong signals";
			System.out.print(s+",");
		}else if(S == 8){
			s = "Strong signals";
			System.out.print(s+",");
		}else if(S == 9){
			s = "Extremely strong signals";
			System.out.print(s+",");
		}if(R == 1){
			r = " unreadable";
			System.out.println(r + ".");
		}else if(R == 2){
			r = " barely readable, occasional words distinguishable";
			System.out.println(r + ".");
		}else if(R == 3){
			r = " readable with considerable difficulty";
			System.out.println(r + ".");
		}else if(R == 4){
			r = " readable with practically no difficulty";
			System.out.println(r + ".");
		}else if(R == 5){
			r = " perfectly readable";
			System.out.println(r + ".");
		}
		
	}

}

此方法是最笨的一种，用switch更简单，这就懒得写了。
