Best way to translate this java code into kotlin

Question

URL url = new URL(urlSpec);
HttpURLConnection connection = (HttpURLConnection)url.openConnection();
InputStream in = connection.getInputStream();
int bytesRead = 0;
         


        

Answer 1

You could use something like this

This operation may be little heavy as a function is created each iteration.

val url = URL("urlSpec")
val connection = url.openConnection() as HttpURLConnection
val `in` = connection.inputStream
val buffer = ByteArray(1024)
var bytesRead: Int? = null
while ({ bytesRead = `in`.read(buffer); bytesRead }() != null) {
        out.write(buffer, 0, bytesRead!!)
}
out.close()
