What is an auto-closeable interface in programming?

An auto-closeable interface is a feature in Java that allows resources to be closed automatically after use, typically in a try-with-resources statement.

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();
}

In this example, the BufferedReader will be closed automatically after the try block.

What happens if I don't use it?

If you don't use an auto-closeable interface, you may need to manually close resources, which can lead to resource leaks if not handled properly.

Are there any other languages that have similar features?

Yes, many languages have similar features. For example, C# has the 'using' statement, and Python has context managers using the 'with' statement.
