Java FileNotFound Exception error even if I have specified the right path

The file can't be found and I don't have to specify the file location because it's in the same directory as the class Test.

The code :

File myFile = new File("aaa.txt");

boolean isExisting = myFile.exists();
System.out.println(isExisting);

try {
  FileReader f = new FileReader(myFile);
  BufferedReader bf = new BufferedReader(f);

  String line = bf.readLine();

  while (line != null) {
    System.out.println(line);
    line = bf.readLine();
  }

  bf.close();

} catch (FileNotFoundException e) {
  System.out.println("Can't find file");

  // e.printStackTrace();

} catch (IOException e) {
  System.out.println("Error");
}

The error (if not catched) :

java.io.FileNotFoundException: aaa.txt (The specified file cannot be found)
at java.base/java.io.FileInputStream.open0(Native Method)
at java.base/java.io.FileInputStream.open(FileInputStream.java:216)
at java.base/java.io.FileInputStream.<init>(FileInputStream.java:157)
at java.base/java.io.FileReader.<init>(FileReader.java:75)
at Testing/Packageeee.Test.main(Test.java:29)

They're all in the same directory

You are almost certainly running from the root of your project. Not from the same directory as your text file.

Assuming that aaa.txt is in a directory called src the following snippet should work:

  String baseDirectory;
  try {
    baseDirectory = new File("./src").getCanonicalPath();
  } catch (IOException e) {
    throw new RuntimeException(e);
  }
  

  File myFile = new File(baseDirectory, "aaa.txt");
