byte[] imageData = // load image data from somewhere File file = new File("image.jpg"); FileUtils.writeByteArrayToFile(file, imageData);
byte[] audioData = // load audio data from somewhere File file = new File("audio.mp3"); FileUtils.writeByteArrayToFile(file, audioData);In both examples, we use the `File` class to specify the file path and name, and the `FileUtils.writeByteArrayToFile` method to save the data to the file. To use the Apache Commons IO library in your Java project, you need to add the library to your classpath. You can download it from the Apache Commons website, or use a build tool like Maven or Gradle to manage dependencies.
