It's very easy, using jersey-client, just include this maven dependency:

  org.glassfish.jersey.core
  jersey-client
  2.25.1

Then invoke it using this example:

String json = ClientBuilder.newClient().target("http://api.coindesk.com/v1/bpi/currentprice.json").request().accept(MediaType.APPLICATION_JSON).get(String.class);

Then use Google's Gson to parse the JSON:

Gson gson = new Gson();
Type gm = new TypeToken() {}.getType();
CoinDeskMessage cdm = gson.fromJson(json, gm);
