Here is an example of how to use the AutoCloseInputStream class from the Apache Commons IO library in Java:

import java.io.FileInputStream;
import java.io.IOException;
import org.apache.commons.io.input.AutoCloseInputStream;

public class MyClass {
    public static void main(String[] args) throws IOException {
        FileInputStream inputStream = new FileInputStream("example.txt");
        try (AutoCloseInputStream autoCloseInputStream = new AutoCloseInputStream(inputStream)) {
            int nextByte = autoCloseInputStream.read();
            while (nextByte != -1) {
                // do something with the byte
                nextByte = autoCloseInputStream.read();
            }
        }
    }
}

In this example, AutoCloseInputStream is wrapping a FileInputStream for the file "example.txt".

The try-with-resources statement is used to automatically close the AutoCloseInputStream when the try block is exited. This also ensures that inputStream is also closed as it is being wrapped by AutoCloseInputStream.

The AutoCloseInputStream is used in the same way as any other InputStream, in this case it reads a byte at a time until the end of the file is reached.

Please note that this is a simple example and in real-world usage, you might want to do more complex processing on the bytes before returning them.
