java.io.FileNotFoundException：无法找到我的文件？

Question

I am trying to implement a text file and a Bufferedreader in my Android Studio project but it is saying that the file cannot be found. screenshot . Help?

Answer 1

Android Studio says that there is a possibility of FileNotFoundException . So, you have to surround the error statement with try and catch block.

try {
    BufferedReader latQ = new BufferedReader(new FileReader("LatinQuotes.txt"));
} catch (FileNotFoundException e) {
    e.printStackTrace();
}

Hope that helps.

Answer 2

As others have said, you need to surround the FileReader constructor with a try...catch block for FileNotFoundException. The reason for this is that the FileReader constructor you are using throws a checked exception. What that means is that the constructor's method signature declares that it "throws FileNotFoundException". This means that anyone that uses the constructor needs to "check" for that exception, or catch it. You should look into the concept of checked exceptions in Java.

Answer 3

The exception appears when a file cannot be created, or the file exists but its permissions are insufficient for changing its content.

Doing try/catch might work.
