I'm working on a Java application that involves file I/O, and I'm dealing with checked exceptions, specifically FileNotFoundException when attempting to read a file. I want to handle this exception gracefully in my code.
Here's a simplified version of what I'm trying to do:
import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;
public class FileProcessor {
public static void main(String[] args) {
String fileName = "sample.txt";
try {
BufferedReader reader = new BufferedReader(new FileReader(fileName));
String line;
while ((line = reader.readLine()) != null) {
System.out.println(line);
}
reader.close();
} catch (IOException e) {
System.err.println("An error occurred while reading the file: " + e.getMessage());
}
}
}
In this code, I'm attempting to read the contents of a file named "sample.txt." If the file doesn't exist or there's an I/O error, a FileNotFoundException or an IOException might occur.
I want to improve the exception handling in my code to provide more meaningful error messages and possibly take different actions based on the exception type. Could you provide a concise Java code example demonstrating how to handle these exceptions effectively while keeping the code clean and readable? Thank you for your assistance!
