How to retrieve the Json response having attachment - json

Question

There is a GET API REST call request, on executed gives a zip file and here are the headers for the response
content-disposition →attachment;filename="results.zip"
content-type →text/plain; charset=UTF-8
On Postman, we can do Send and Download and can save the resultant zip file
I use RestAssured to test the REST API calls.
Can somebody help me how to retrieve the resultant zip file from the API call?

Update:
I found a solution from Rest Assured, where we can get the Response as either InputStream or Byte Array and further write to a ZipFile.
As InputStream:-
// Get the response as Input Stream
InputStream is = result.getBody().asInputStream();
OutputStream stream = new FileOutputStream("D:\\Test.zip");
int read = 0;
byte[] bytes = new byte[1024];
while ((read = is.read(bytes)) != -1) {
stream.write(bytes, 0, read);
}
System.out.println("Zip file captured successfully");
As ByteArray:-
// Get the response as ByteArray
byte[] arraybyteResponse = result.getBody().asByteArray();
ByteBuffer buffer = ByteBuffer.wrap(arraybyteResponse);
OutputStream os = new FileOutputStream("D:\\Test.zip");
WritableByteChannel channel = Channels.newChannel(os);
channel.write(buffer);
System.out.println("Zip file captured successfully");
