How can I add Authorization and Date/time header in the below code?

I am creating a Java Rest api to create users on Google Duo admin. I am following the documentation https://duo.com/docs/adminapi and they need auth and date/time header. I am fairly new to java can anyone guide me?
This is the updated code which I with authentication and date/time header but now getting the below error.
UPDATED CODE

final String POST_PARAMS = "{\n" + "\"userId\": 101,\r\n" +
" \"id\": 101,\r\n" +

postConnection.setRequestProperty("Authorization", basicAuth);
postConnection.setRequestProperty("Date", dateTime);
postConnection.setDoOutput(true);

os.write(POST_PARAMS.getBytes());
os.flush();
os.close();

System.out.println("POST Response Message : " + postConnection.getResponseMessage());
if (responseCode == HttpURLConnection.HTTP_CREATED) { //success
BufferedReader in = new BufferedReader(new InputStreamReader(
postConnection.getInputStream()));
String inputLine;
StringBuffer response = new StringBuffer();
while ((inputLine = in.readLine()) != null) {
response.append(inputLine);
}
in.close();
// print result
System.out.println(response.toString());
} else {
System.out.println("POST NOT WORKED");
}
}
}
ERROR
{
"code": 40101,
"message": "Missing request credentials",
"stat": "FAIL"
}
Response code: 401 (Unauthorized); Time: 2022ms; Content length: 73 bytes

As I have read the documentation, the authorization is Basic:
String userCredentials = "username:password";
String basicAuth = "Basic " + new String(Base64.getEncoder().encode(userCredentials.getBytes()));
For date is this:
String dateTime = OffsetDateTime.now().format(DateTimeFormatter.RFC_1123_DATE_TIME); //RFC_1123 == RFC_2822
In their documentation they require RFC 2822 format. We already have declared RFC 1123 in DateTimeFormatter, which practically it is the same.
And this is the way you can add them in headers:
postConnection.setRequestProperty("Authorization", basicAuth);
postConnection.setRequestProperty("Date", dateTime);

How to run this java file?

I have been told to execute this java program which is linked to a virtual number, when you run it, the output is a number code or whatever it is that i sent the number in sms.
I am using selenium and maven and also in the eclipse program and was told to use the testng plugin. They asked me to use #test annotations in an .xml file to execute it.
Im knew to programming and to be honest i have no idea how to write the xml file in order to run this and when i ask the person who told me to do this all they do is say google it and i have tried but i havent found anything.
the code is:

If I understand correctly, they want you to convert this into a TestNG test which shouldn't be too difficult as the test and methods are already built. Considering you don't know Java, nor programming, I suggest watching a couple of Youtube videos to get you up to speed on TestNG. I believe once you get your feet wet with TestNG, much of the code along with how to convert it will make more sense.

#Test annotation will behave like a void main for each test (which is a method with the #Test annotation).
You can add a dependency in your maven pom.xml file for junit or testng (any of them will bring this annotation), then, you can trigger the test by running the method from your IDE, or from command line you can simple use:
mvn clean test - to trigger all existent tests
mvn clean test -Dtest=your.package.TestClassName - to trigger tests from a class
mvn clean test -Dtest=your.package.TestClassName#particularMethod - to trigger a specific test

i also try to get cookies flow this line setCookies(conn.getHeaderFields().get("Set-Cookie")); but it's always return null String so i have to make getCookies() function.
i always receive status 200 OK. So is there any support to help me or another code can do this task.
Thanks in Advance.

HTTP requests in android

I am currently working on a school project using android. I have java code that sends an HTTP request to a server. It works just find on my laptop using eclipse, but when I try it on my android tablet (an android trio using android 4.4), it does not work. Instead it returns an error (An error occurred while sending the request: in the catch). It is going by the try block and moving to the catch block.
I am attaching the code used for the HTTP request below. I will be leaving out the server information for security reasons. I know the code works, like I said It works on my desktop. Why won't it work with my tablet? Can someone give me a hand with this?

I want to get result json from goeuro api

I am developing API in java to get json from GoEuro API is available at github. i want to know parameter i need to send with POST method and get result as json and combined with my custom logic.
Here is my java code to call api.

import java.net.HttpURLConnection;
import java.net.MalformedURLException;

HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setRequestMethod("POST");
// conn.setRequestMethod("GET");
conn.setRequestProperty("Accept", "application/json");
if (conn.getResponseCode() != 200) {
throw new RuntimeException("Failed : HTTP error code : " + conn.getResponseCode());
}
BufferedReader br = new BufferedReader(new InputStreamReader((conn.getInputStream()), "UTF-8"));
String output;
System.out.println("Output from Server .... \n");
while ((output = br.readLine()) != null) {
System.out.println(output);
}
conn.disconnect();
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
}
I am not good in nodejs. Any Help would be appreciated.

First of all the url needs to be only this http://www.goeuro.com/GoEuroAPI/rest/api/v3/search
Then you need to add parameters using params in request.
Your if response != 200 has to be after you make the request.
public static void main(String[] args) {
try {
URL url = new URL("http://www.goeuro.com/GoEuroAPI/rest/api/v3/search);
HttpURLConnection con = (HttpURLConnection) url.openConnection();
con.setRequestMethod("POST");
con.setRequestProperty("Accept", "application/json");
String urlParameters = "departure_fk=318781&departure_date=16%2F04%2F2017&arrival_fk=380553&trip_type=one-way&adults=1&children=0&infants=0&from_filter=Coventry+%28COV%29%2C+United+Kingdom&to_filter=London%2C+United+Kingdom&travel_mode=bus&ab_test_enabled=";
// Send post request
con.setDoOutput(true);
DataOutputStream wr = new DataOutputStream(con.getOutputStream());
wr.writeBytes(urlParameters);
wr.flush();
wr.close();
int responseCode = con.getResponseCode();
System.out.println("\nSending 'POST' request to URL : " + url);
System.out.println("Post parameters : " + urlParameters);
System.out.println("Response Code : " + responseCode);
BufferedReader in = new BufferedReader(
new InputStreamReader(con.getInputStream()));
String inputLine;
StringBuffer response = new StringBuffer();
while ((inputLine = in.readLine()) != null) {
response.append(inputLine);
}
in.close();
//print result
System.out.println(response.toString());
}

However, i found my answers from github issue.
Here are required params and there expected json format.
{
"arrivalPosition":{
"positionId":380244
},
"currency":"EUR",
"departurePosition":{
"positionId":380553
},
"domain":"com",
