java.io.FileNotFoundException，找不到文件 [英] java.io.FileNotFoundException, file not being found

问题描述

我只是想逐行阅读一个文件。
这是为了简单，但我不能把它正确！

  String fileName =C ：/Users/Diogo/Desktop/Krs_Grafo/Graph.txt; 
 FileReader file = new FileReader（fileName）; 
 BufferedReader inputStream = new BufferedReader（file）; 
 System.out.println（inputStream.readLine（））; 
  

我不断收到错误：

 线程main中的异常java.io.FileNotFoundException：C：\Users\Diogo\Desktop\Krs_Grafo\Graph.txt（O sistemanãopode encontrar o arquivo especificado） 
在java.io.FileInputStream.open（本地方法）
在java.io.FileInputStream。< init>（FileInputStream.java:120）
在java.io.FileInputStream。< ; init>（FileInputStream.java:79）
 at java.io.FileReader。< init>（FileReader.java:41）
 at krs_grafo.Krs_Grafo.main（Krs_Grafo.java:51）
 Java结果：1 
  

系统无法找到文件，但我确定它在那里！
我在Windows 7上使用Netbeans 7.0。

在评论中，它正在搜索Graph而不是Graph.txt。这是从以前的执行，我没有扩展尝试。所以，我编辑它是连贯的。它仍然不起作用。

解决方案

这里的问题是文件名实际上是 Graph.txt。 txt ，因为扩展名被隐藏，所以我看不到。

感谢用户Michael Brewer-Davis在评论中询问在给定的目录中输出cd和dir。

同时指出/和\\工作得很好。

I just wanted to read a file line by line. This was meant to be simple, but i just can't get it right!

String fileName = "C:/Users/Diogo/Desktop/Krs_Grafo/Graph.txt";
FileReader file = new FileReader(fileName);
BufferedReader inputStream = new BufferedReader(file);
System.out.println(inputStream.readLine());

i keep getting the error:

Exception in thread "main" java.io.FileNotFoundException: C:\Users\Diogo\Desktop\Krs_Grafo\Graph.txt (O sistema não pode encontrar o arquivo especificado)

at java.io.FileReader.<init>(FileReader.java:41)
at krs_grafo.Krs_Grafo.main(Krs_Grafo.java:51)
Java Result: 1

The system cant find the file, but i'm sure as hell it is there! I'm using Netbeans 7.0 on a Windows 7.

Any suggestions?

AS SAID IN THE COMMENTS, it was searching for "Graph" and not "Graph.txt". This was from a previous execution where I tried without the extension. So, I edited it to be coherent. It still doesn't work.

解决方案

The problem here is that the file name was actually "Graph.txt.txt" wich I couldn't see because the extensions were hidden.

Thanks to user "Michael Brewer-Davis" who asked in the comments for "output of cd and dir in the given directory".

Also point out that either / and \\ work just fine.
