How has AutoCloseable changed in recent Java versions?

The AutoCloseable interface in Java has remained consistent in its core functionality, allowing developers to define classes whose resources can be automatically closed when they are no longer needed, particularly in resource management scenarios such as file handling, socket communication, etc. However, recent versions of Java (especially Java 7 and later) have improved the handling of AutoCloseable instances through the try-with-resources statement, simplifying resource management and reducing boilerplate code.

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();
    }
