How do I create a try-with-resources statement in Java?

To create a try-with-resources statement, you need to declare your resources within the parentheses of the try statement.

Can you give me an example of that?

Sure! 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 by the catch block, allowing you to handle it gracefully.

Is it mandatory to use try-with-resources for all resources?

No, it's not mandatory, but it's a good practice as it ensures that resources are closed automatically.
