Java：文件沒有打開給出例外

-1

我通過filenamechooser取得文件名，並將它發送給我想要的處理方法，但問題是它不接受文件名。我正在使用JPcap打開文件。當我硬編碼，它給了我完美的效果，但是當我發送的文件名也給我exception.Here是我的代碼Java：文件沒有打開給出例外

  JpcapCaptor captor = JpcapCaptor.openFile("E:\\10.pcap");

我把這個文件的打印語句，這讓我這個

  System.out.println("E:\\10.pcap");

在控制檯上我得到這個

E：\ 10.pcap

但是當我從我的GUI發送此文件名來此OPENFILE功能，它給了我這個例外，雖然當我把這個文件名，它也是相同的E的打印語句：\ 10 .pcap

確定這個文件是否存在？也許你需要先創建它？

嘗試

File f = new File("E:\\10.pcap"); 
if(!f.exists()){ 
    f.createFile(); //or create() - i forget 
} 
//then do the pcap shit

或者你可以使用try {} catch（Exception ex）{} – Jimmt 2012-02-14 05:26:00

是的文件exists.The代碼工作正常，當我硬編碼它 – Xara 2012-02-14 05:30:51
