How can I download a file by using box-java-sdk?

[github-actions]

Here is an example of how to download a file using the box-java-sdk:

1. Create a BoxAPIConnection object and authenticate the user:

BoxAPIConnection api = new BoxAPIConnection("ACCESS_TOKEN");

2. Get the BoxFile object for the file you want to download:

BoxFile file = new BoxFile(api, "FILE_ID");

3. Get the file's download URL:

String downloadUrl = file.getDownloadURL();

4. Download the file using the download URL:

URL url = new URL(downloadUrl);
URLConnection connection = url.openConnection();
InputStream in = connection.getInputStream();
ByteArrayOutputStream out = new ByteArrayOutputStream();

byte[] buffer = new byte[1024];
int n = 0;
while ((n = in.read(buffer)) != -1) {
    out.write(buffer, 0, n);
}
byte[] fileData = out.toByteArray();

The fileData byte array now contains the contents of the downloaded file. You can write this data to a file on disk, send it to a database, or do whatever you need to with it.
