信号报告-java

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.

import java.util.Scanner;

public class Main {

	public static void main(String[] args) {

		Scanner in = new Scanner(System.in);
//这里必须注释掉否则提交不过去
//System.out.println("输入信号");
//输入信号
		int a = in.nextInt();
		int readability = a / 10;
		int strength = a - readability * 10;
		String s = "";
		String r = "";

//s switch
		switch(strength) {
		case 1:
			s = "Faint signals, barely perceptible";
			break;
		case 2:
			s = "Very weak signals";
			break;
		case 3:
			s = "Weak signals";
			break;
		case 4:
			s = "Fair signals";
			break;
		case 5:
			s = "Fairly good signals";
			break;
		case 6:
			s = "Good signals";
			break;
		case 7:
			s = "Moderately strong signals";
			break;
		case 8:
			s = "Strong signals";
			break;
		case 9:
			s = "Extremely strong signals";
			break;
		default:
			break;
		}
//r switch
		switch(readability) {
		case 1:
			r = "unreadable";
			break;
		case 2:
			r = "barely readable, occasional words distinguishable";
			break;
		case 3:
			r = "readable with considerable difficulty";
			break;
		case 4:
			r = "readable with practically no difficulty";
			break;
		case 5:
			r = "perfectly readable";
			break;
		}
//输出
		System.out.println(s+","+" "+r+".");
