This example demonstrates how to effectively test code that utilizes InputStream and Reader in Java, focusing on different approaches for handling input streams and file reading.


        <?php
            // Example of reading from InputStream
            $inputStream = fopen("example.txt", "r");
            while (($line = fgets($inputStream)) !== false) {
                echo $line;
            }
            fclose($inputStream);

            // Example of reading from Reader
            $reader = new SplFileObject("example.txt");
            while (!$reader->eof()) {
                echo $reader->fgets();
            }
        ?>
