I'm trying to read some numbers from a text file in java to defines some shapes and display them in the GUI window, however every time I try to run the code and import the values in the text file it throws a FileNotFoundException even though the file is in the same directory and exists and opens fine.

Code inserted below and file structure for the project.

Any ideas on how to solve this please? Much appreciated in advance.

I have checked the file actually exists which it does and if the file opens and shows the data which it also does and that the file isn't corrupt which it isn't.

public static void addShapes(){
    BounceBox box = new BounceBox(700,500);        
    FileInputStream fileIn = new FileInputStream("ex3.txt");
    Scanner scan = new Scanner(fileIn);

    box.start();
}

If you see the error, it says

Uncompilable source code - unreported exception java.io.FileNotFoundException; must be caught or declared to be thrown

This means that it's not a runtime exception with the file not being found, but it's a compile time exception. It's due to the below line:

FileInputStream fileIn = new FileInputStream("ex3.txt");

It means that there is a possibility of FileNotFoundException at that line, and that it should either be added to the method signature as below:

public static void addShapes() throws FileNotFoundException {
        BounceBox box = new BounceBox(700,500);

        FileInputStream fileIn = new FileInputStream("ex3.txt");
        Scanner scan = new Scanner(fileIn);

        box.start();
    }

or the line should be surrounded with a try-catch block, catching the FileNotFoundException as below:

public static void addShapes(){
    BounceBox box = new BounceBox(700,500);
    try {
        FileInputStream fileIn = null;
        fileIn = new FileInputStream("ex3.txt");
        Scanner scan = new Scanner(fileIn);
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    }

    box.start();
}

Java FileNotFound error even though files exists and is in same , If you see the error, it says. Uncompilable source code - unreported exception java.io.FileNotFoundException; must be caught or declared to be� The file exists, and you can even read it (for example, the command file shank-linux-120720110-1-bin displays something like “ELF 32-bit LSB executable …”), and yet when you try to execute it you're told that the file doesn't exist.

public static void addShapes() {
    BounceBox box = new BounceBox(700,500);
    try {
        FileInputStream fileIn = new FileInputStream("ex3.txt");
        Scanner scan = new Scanner(fileIn);
    } catch(FileNotFoundException e) {
        e.printStackTrace();
    }
    box.start();
}

Solving java.io.FileNotFoundException, FileNotFoundException – How to solve File Not Found Exception Open the file for writing, without removing its current content. If the file exists and is a directory, the following exception is thrown: in my directory/path as String”E: estilename.png”during runtime and get a ioexception file not found error. It turned out that the file didn't exist, even though it looked like it did. The problem was that Windows 7 was configured to "Hide file extensions for known file types." This means that if file appears to have the name "data.txt" its actual filename is "data.txt.txt". Hope this helps others save themselves some hair.

You are getting a "Unreported Exception" which means your code can throw an exception(which is FileNotFound Exception) and you are not catching it. So surround your code with try-catch.

 FileInputStream fileIn = null;

    try {
        fileIn = new FileInputStream("ex3.txt");
    } catch (FileNotFoundException ex) {
        // catch your exception here.
    }

    Scanner scan = new Scanner(fileIn);

FileNotFoundException in Java, A quick and practical guide to FileNotFoundException in Java. A file with the specified pathname does not exist; A file with the specified pathname does exist but is inaccessible for try with a fail-safe one; Just log an error: this error should not stop the "BusinessException: even creation is not possible. I did do a chmod 664 on the file, the same as the other files, but it did nothing. Should I chown. I also wrote some code for File.exists() and it came back false, so I am drawing a complete blank.

I encountered the same issue today, which took me about two hours to partially figured it out. It was so annoying. Depending on how your class code is structured, Java does not allow you to read text file within the method definition. Try reading it in the main method, then take that object (FileInputStream) as input to your addShapes() method. Let me know if it works :)

How to Avoid the Java FileNotFoundException When Loading , Java programs cannot easily load files once they have been compiled into the resource folder is seldom in the same location on disk as it is in our source code. If we run the above code in an IDE, the file loads without an error. Even if we changed the path to /input.txt the original code could not load� The FileNotFoundException is thrown when attempting to access a file that doesn’t exist, so let’s just right into some code to see how it works. For this example, we’re using the Book class that we’ve used in the past to create a couple books, which we then output to a new file in the form of JSON .

[PDF] File I/O & error-handling, In Java, we have exception handling, a powerful tool for ensuring response to error conditions. • Java When one of the statements throws an exception,. I have to create a histogram based on grades students received that are in a text file named "midterm.txt.". I've posted what I've come up with so far, but to be honest I don't know if I'm even on the right path because I can't get the program to run to see how it behaves.

Java Exception Handling - FileNotFoundException, A close look at the Java FileNotFoundException, with sample code illustrating how to functional code samples showing how this error might come about, so let's get to it! Logging.log(exception, false); } } /** * Read Books from Json file. public String getTitle() { return title; } /** * Publish current book. * If� Why does it throws DirectoryNotFoundException even though Directory.Exists returns true? So I'm making a really small console application that organizes some directories, because I want to know at least some basic things on how to treat files and directories on C#, for this I used Directory.Move, like this:

Debugging System.IO.FileNotFoundException, FileNotFoundException isn't always as simple as it seems. In all instances this error is caused by trying to access a file that isn't I'm trying to load a file that doesn't exist on the file system ( non-existing.file ). An error similar to the one above is the Could not load file or assembly 'assembly' or one of its� Any non-directory file created by a Java application is guaranteed to be a normal file. Where it is required to distinguish an I/O exception from the case that the file is not a normal file, or where several attributes of the same file are required at the same time, then the Files.readAttributes method may be used.

  • you know that it's in the same folder but java doesn't know it. You have to put your code in a try/catch to show that you're prepared to handle if something goes wrong.
  • @JustAFellowCoder Yes exactly. And ex3.txt is in the same folder as the class file and yes the class file is in the package. Still same issue.
  • @NikosTzianas hey may choose to throw it, although not good practice.
  • Does surrounding it in try/catch work? If that's the case then Madhu Bhat answered the question correctly.
  • Also try putting the path of the file starting from the package the package or ignoring the package. So if it is in a package com.bif and in folder rsc then try "com/bif/rsc/ex3.txt" or simply "rsc/ex3.txt" (sorry for the spam)
  • Tried both but still same issue. Any other ideas ?
  • If you have tried both, @MahmoudYassine, then the error that you are getting would not be the same. Can you please confirm if you're getting a different error after adding my suggestion?
  • Just ran the code with your second edit and the error is as follows: run: java.io.FileNotFoundException: ex3.txt (The system cannot find the file specified) at java.io.FileInputStream.open0(Native Method) at java.io.FileInputStream.open(FileInputStream.java:195) at java.io.FileInputStream.<init>(FileInputStream.java:138) at java.io.FileInputStream.<init>(FileInputStream.java:93) at bounceboxapp.Main.addShapes(Main.java:131) at bounceboxapp.Main.main(Main.java:37)
  • @MahmoudYassine yes now the file is not being found, if you see it's a different error from before.
  • Just ran the code again and put in the full path to file and has worked!!! Thank you for your help!!
  • Just an advice, @JuanRomo, you need to add explanation with an answer, since just by looking at a piece of code, the OP might not understand the reasoning behind the answer. Adding an explanation helps. And welcome to StackOverflow :)
