Provide examples where you used checked exceptions in your code.

In Java, I used checked exceptions, for example, when working with the file system and input-output, where methods can throw IOException. This forces explicit handling of read/write errors, increasing code reliability.

Example:

public void readFile(String path) throws IOException {
    try (BufferedReader reader = new BufferedReader(new FileReader(path))) {
        String line;
        while ((line = reader.readLine()) != null) {
            System.out.println(line);
        }
    }
}

Here, the method declares throws IOException, and the calling code must handle or propagate this exception.

I also used checked exceptions when working with JDBC — SQLException requires mandatory handling, which helps control errors when working with databases.

Using checked exceptions is useful when an error is expected and requires mandatory handling, for example, when interacting with external resources.
