nicolas filotto's answer on here perfect: how make post curl request in java

here if rather stay on page:

if use davidwebb lightweight java http-client calling json rest-services , proceed next:

webb webb = webb.create(); jsonobject result = webb     .post("https://api.gupshup.io/appsdk/api/components/adduser")     .header("content-type", "application/x-www-form-urlencoded")     .header("apikey", "xxxx")     .body("name=abcd&email=test@test.com.com&id=abc")     .asjsonobject()     .getbody();
