What are some examples of AutoCloseable in Java?

Can you give me some examples of AutoCloseable in Java?

Sure! The AutoCloseable interface in Java is used for automatic resource management. A common example is using it with file streams.

How does it work with file streams?

When you use a file stream within a try-with-resources statement, it automatically closes the stream after the block is executed.

Can you show me a code snippet?

Absolutely! Here's a simple example:

try (FileInputStream fis = new FileInputStream("file.txt")) {
    // Read from the file
} catch (IOException e) {
    e.printStackTrace();
}

In this code, fis will be closed automatically.

What other resources can implement AutoCloseable?

Other resources include database connections, sockets, and any class that implements the AutoCloseable interface.
