File not found in same folder Java

Question

I am trying to read a file in Java. I wrote a program and saved the file in the exact same folder as my program. Yet, I keep getting a FileNotFoundException. Here is the code: ``` public static void main(String[] args) throws IOException { Hashtable ht = new Hashtable(); File f = new File("file.txt"); ArrayList al = readFile(f, ht); } public static ArrayList readFile(File f, Hashtable ht) throws IOException{ ArrayList al = new ArrayList(); BufferedReader br = new BufferedReader(new FileReader(f)); String line = ""; int ctr = 0; } ... return al; } ``` Here is the stack trace: ``` Exception in thread "main" java.io.FileNotFoundException: file.txt (The system cannot find the file specified) at java.io.FileInputStream.open(Native Method) at java.io.FileInputStream.(Unknown Source) at java.io.FileReader.(Unknown Source) at csfhomework3.ScramAssembler.readFile(ScramAssembler.java:26) at csfhomewor…

Accepted Answer

Because the `File` isn't where you think it is. Print the path that your program is attempting to read.

```
File f = new File("file.txt");
try {
    System.out.println(f.getCanonicalPath());
} catch (IOException e) {
    e.printStackTrace();
}
```

Per the `File.getCanonicalPath()` javadoc, A canonical pathname is both absolute and unique. The precise definition of canonical form is system-dependent.
