HTTP Methods - GET and DELETE

Demonstrate a method for sending HTTP requests that don't have a request body, such as for GET or DELETE requests. Java

    //  The Accept and Accept-Encoding headers are automatically added by default.

        }

    //  The DELETE request that is sent looks like this.
    //  The empty Accept-Encoding header value means we only want non-compressed responses.
