According to your code, it seems that you want to create a new device identity using the REST API with HTTP PUT Method.

However, in your code, the query parameter top=100 is not necessary and the request body {deviceId: "iotdevice1"} is missing.

Here is my working code.

String body = "{deviceId: \"iotdevices1\"}";
ClientResponse response = webResource.path("/iotdevices1").queryParam("api-version", "2016-02-03")
                    .header("Content-Type", "application/json")
                    .header("Authorization",
                            "SharedAccessSignature sr=xxxx.azure-devices.net&sig=xxxxxxxx&se=1497357420&skn=iothubowner")
                    .put(ClientResponse.class, body);

Hope it helps. Any concern, please feel free to let me know.

Update :

For deleting a existing device identity, please see the REST API reference and see the code below.

ClientResponse response = webResource.path("/iotdevices1").queryParam("api-version", "2016-02-03")
                    .header("Content-Type", "application/json")
                    .header("If-Match", "*")
                    .header("Authorization",
                            "SharedAccessSignature sr=xxxx.azure-devices.net&sig=xxxxxx&se=1497490976&skn=iothubowner")
                    .delete(ClientResponse.class);

Please take note of the header If-Match above.
