Error in getting oauth token using httpClient

I am trying to get an oauth token using http client but it results in HTTP/1.1 401 Unauthorized error. I initially tried using a curl request as follows and it was success. ( here original parameter values are not shown for the security purpose)

   curl --request POST --url oauthtokenHttpsurl  --header 'content-type: application/json' --data '{"client_id":"clientId","client_secret":"client_secret","audience":"audienceurl","grant_type":"credentials"}'

Then I tried to implement the same in java using apache httpclient as follows but it's giving a 401 Unauthorized error

   import java.io.IOException;
    import java.nio.charset.StandardCharsets;

    import org.apache.commons.io.IOUtils;
    import org.apache.http.HttpResponse;
    import org.apache.http.client.methods.HttpPost;
    import org.apache.http.entity.StringEntity;
    import org.apache.http.impl.client.CloseableHttpClient;
    import org.apache.http.impl.client.HttpClientBuilder;
    import org.apache.http.message.BasicHeader;
    import org.apache.http.protocol.HTTP;


    public class TestOAuthPost {

    public static void main(String[] args) {
        try (CloseableHttpClient httpClient = HttpClientBuilder.create().build()) {

            HttpPost httppost = new HttpPost("oauthtokenHttpsurl");
            JsonObject jsonObj = new JsonObject();
            jsonObj.addProperty("grant_type", "credentials");
            jsonObj.addProperty("audience", "audienceurl");
            jsonObj.addProperty("client_id", "client_id");
            jsonObj.addProperty("client_secret", "client_secret");
            StringEntity se = new StringEntity(jsonObj.toString());
            se.setContentType(new BasicHeader(HTTP.CONTENT_TYPE, "application/json"));
            httppost.setEntity(se);

            // Execute HTTP Post Request
            HttpResponse response = httpClient.execute(httppost);
            String result = IOUtils.toString(response.getEntity().getContent(), StandardCharsets.UTF_8);
      // 401 Unauthorized error
      } catch (IOException e) {

            System.out.println("erss");

        }
        }
    }

I am working with httpclient library and in oauth for the first time.

Could somebody please give some guidance.

Above code is working fine. It was my mistake, sorry for the mess. There was a copy minor spelling mistake in the client id. Anyway, I hope it will help somebody in the future
