What is the try-with-resources statement in Java?

The try-with-resources statement is a feature in Java that simplifies resource management, ensuring that resources are closed automatically.

Can you give me an example of how to use it?

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 in the catch block, and the resources will still be closed automatically.

Is it mandatory to use try-with-resources?

No, it's not mandatory, but it's highly recommended as it makes your code cleaner and helps prevent resource leaks.
