20                     if(i < tempList.length - 1) {
21                         System.out.print(tempList[i] + "    ");
22                     }
23                     else {
24                         System.out.println(tempList[i]);
25                     }
26                 }
27             }
28         } catch (IOException ex) {
29             ex.printStackTrace();
30         }
31     }

以上代码检查后发现没有什么问题，但运行时报错

百思不得其解，最终发现是因为文件路径包含中文(lll￢ω￢)

重构系统文件目录，改用英文刻不容缓！！！ㄟ( ▔, ▔ )ㄏ
