making a program that opens and reads a file. This is my code: import java.io.*; public class FileRead{ public static void main(String[] args){ try{ File file = new File("hello.txt"); System.out.println(file.getCanonicalPath()); FileInputStream ft = new FileInputStream(file); DataInputStream in = new DataInputStream(ft); BufferedReader br = new BufferedReader(new InputStreamReader(in)); String strline; while((strline = br.readLine()) != null){ System.out.println(strline); } in.close(); }catch(Exception e){ System.err.println("Error: " + e.getMessage()); } } } but when I run, I get this java.io.filenotfoundexception eclipse error: C:\Users\User\Documents\Workspace\FileRead\hello.txt Error: hello.txt (The system cannot find the file specified) my FileRead.java and hello.txt where in the same directory that can be found in: C:\Users\User\Documents\Workspace\FileRead I'm wondering what I am doing wrong? java file share|improve this question edited Oct 8 at 10:27 eddie 642418 asked Jul 19 '12 at 2:18 gadss 4,2841654104 2 Please don't use DataInputStream if you want to read text, its more confusing than useful. –Peter Lawrey Aug 15 '12 at 11:30 in windows system sometimes what happens is.. you keep show file extension feature off and you try naming file as xyz.txt it will create a file having name xyz.txt.txt and hence your code will not be able to find that –VD' Jun 2 '13 at 5:58 add a comment| 7 Answers 7 active oldest votes up vote 6 down vote accepted I have copied your code and it runs fine. I suspect you are simply having some problem in the actual file name of hello.txt, or you are running in a wrong directory.

Basically, I have a file created called "word.txt" and whenever I run the program it gives me this error: Exception in thread "main" java.io.FileNotFoundException: word.txt (The system cannot find the file specified)
at java.io.FileInputStream.open(Native Method)
at java.io.FileInputStream.
at java.util.Scanner.
at Hangman1.main(Hangman1.java:6)
Here's my code: import java.io.File;
import java.util.*;
public class Hangman1 {
public static void main(String[] args) throws Exception {
Scanner input = new Scanner(new File("word.txt"));
String in = "";
in = input.nextLine();
}
}
Ironically, I created the file "word.txt" in the same directory as my java file and yet, it's still giving me that error. peeskillet Answer Email {} Share Put the word.txt directly as a child of the project root folder and a peer of src Project_Root src word.txt Disclaimer: I'd like to explain why this works for this particular case and why it may not work for others. Why it works: When you use File or any of the other FileXxx variants, you are looking for a file on the file system relative to the "working directory". The working directory, can be described as this: When you run from the command line C:\EclipseWorkspace\ProjectRoot\bin > java com.mypackage.Hangman1 the working directory is C:\EclipseWorkspace\ProjectRoot\bin. With your IDE (at least all the ones I've worked with), the working directory is the ProjectRoot. So when the file is in the ProjectRoot, then using just the file name as the relative path is valid, because it is at the root of the working directory. Similarly, if this was your project structure ProjectRoot\src\word.txt, then the path "src/word.txt" would be valid. Why it May not Work For one, the working directory could always change. For instance, running the code from the command line like in the example above, the working directory is the bin. So in this case it will fail, as there is not bin
