### Asynchronous Get ([.kt][AsynchronousGetKotlin], [.java][AsynchronousGetJava])

Download a file on a worker thread, and get called back when the response is readable. The callback is made after the response headers are ready. Reading the response body may still block. OkHttp doesn't currently offer asynchronous APIs to receive a response body in parts.

       2. However, you should still add Javadoc if there are caveats around
          calling a method that are not immediately obvious from reading the
          method's implementation in isolation.
       3. You can omit Javadoc for simple classes, e.g. where they are a
