【从零开始学Java】第二周

19             case 3: ge = "Weak signals";    break;
20             case 4: ge = "Fair signals";    break;
21             case 5: ge = "Fairly good signals";    break;
22             case 6: ge = "Good signals";    break;
23             case 7: ge = "Moderately strong signals";    break;
24             case 8: ge = "Strong signals";    break;    
25             case 9: ge = "Extremely strong signals";    break;
26         }
27         
28         switch(sw) {
29             case 1: shi = "unreadable";
30                 break;
31             case 2: shi = "barely readable, occasional words distinguishable";
32                 break;
33             case 3: shi = "readable with considerable difficulty";
34                 break;
35             case 4: shi = "readable with practically no difficulty";
36                 break;
37             case 5: shi = "perfectly readable";
38                 break;
39         }
40         System.out.print(ge + ", " + shi + ".");
41     }
42 
43 }

变量必须先初始化，不然会报错。
