Amadeus api return 401 client Credentials are invalid - amadeus

Question

Amadeus api returns 401 client Credentials are invalid. Please check the code below. I included symbols [ and ] into credential strings.
// here xxxxx are placeholders for real credentials (strings)
Amadeus amadeus = Amadeus.builder("[xxxxxx]","[xxxxxx]")
.setHostname("test").setHost("test.api.amadeus.com").setSsl(true).setLogLevel("debug").build();
//HttpHandler sh = new HttpHandler();
//FlightDestination[] des = sh.FlightDest();
//id = sh.id();
try {
FlightDestination[] destination1 = amadeus.shopping.flightDestinations.get(Params.with("origin", "LON"));
id = destination1[0].getOrigin();
name = destination1[0].getDestination();
email = destination1[0].getType();
}catch (ClientException e)
{
id=e.getMessage();
}catch (NetworkException e)
{
id = e.getMessage();
}catch (NotFoundException e)
{
id = e.getMessage();
}catch (ServerException e)
{
id = e.getMessage();
}catch (ParserException e)
{
id = e.getMessage();
}catch (ResponseException e)
{
id = e.getMessage();
}

You don't need the [ ] and you need to replace them by the API_KEY and the API_SECRET that you get following this guide.
You can find examples using the Java SDK here and here.
Amadeus amadeus = Amadeus.builder("API_KEY", "API_SECRET").build();
/* Find cheapest destinations from London */
FlightDestination[] flightDestinations = amadeus.shopping.flightDestinations.get(Params.with("origin", "LON"));
System.out.println(flightDestinations[0]);
