How does try-with-resources work in Java?

Can you explain how try-with-resources works in Java?

Sure! Try-with-resources is a feature in Java that automatically closes resources like files or sockets when done.

What types of resources can I use with try-with-resources?

You can use any resource that implements the AutoCloseable interface, such as InputStream, OutputStream, and more.

Can you give me a code example?

Of course! Here's a simple example:

try (BufferedReader br = new BufferedReader(new FileReader("file.txt"))) {
    String line;
    while ((line = br.readLine()) != null) {
        System.out.println(line);
    }
} catch (IOException e) {
    e.printStackTrace();
}

What happens if an exception occurs?

If an exception occurs, it will be caught in the catch block, and the resources will still be closed automatically.
