How to call API (Oauth 1.0)?

I am trying to call this API (Oauth1.0 standard):

https://appcenter.intuit.com/api/v1/Connection/Reconnect

And what I am doing is : (It am working on java)

Base64Encoder baseEncoder = Base64Encoder.getInstance();
            CloseableHttpClient httpclient = HttpClients.createDefault();
            HttpGet httpGet = new HttpGet("https://appcenter.intuit.com/api/v1/connection/reconnect");
            StringBuilder headerReq = new StringBuilder();
            headerReq.append("OAuth ");
            headerReq.append("oauth_token=\"").append(OAUTHTOKEN).append("\"");
            headerReq.append(", oauth_consumer_key=\"").append(CUNSUMER_KEY).append("\"");
            headerReq.append(", oauth_signature_method=\"base64\"");
            headerReq.append(", oauth_signature=\"")          .append(baseEncoder.encode(PropsUtil.get(OAUTH_CONSUMER_SECRET).getBytes()))
                    .append(baseEncoder.encode("&".getBytes()))            .append(baseEncoder.encode(symmetricEncrypter.decryptData(OAUTH_TOKEN_SECRET).getBytes())).append("\"");
            headerReq.append(", oauth_version=\"1.0\"");
            httpGet.addHeader("Authorization", headerReq.toString());
            CloseableHttpResponse response = httpclient.execute(httpGet);
            try {
                System.out.println("Responsee::"+ response.getStatusLine());
}

And, the response what I am getting is:

<?xml version="1.0" encoding="utf-8"?>
<PlatformResponse xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://platform.intuit.com/api/v1">
  <ErrorMessage>This API requires Authorization.</ErrorMessage>
  <ErrorCode>22</ErrorCode>

Can you please suggest me what I am missing while creating request for Oauth1.0 standard or Please, anyone can provide me the sample code of Oauth1.0 request example on that standard.

Thank you very much.

PFB working code. Hope it will be useful.

This is the working HTTP GET requestcode in java when all keys are in hand. Hope it does your work.

Here is a builder I created to build the OAuth v1 Authorization header. You may find it useful.

https://gist.github.com/robotdan/33f5834399b6b30fea2ae59e87823e1d

Example usage calling Twitter:

String authorizationHeader = new OAuth1AuthorizationHeaderBuilder()
         .withMethod("POST")
         .withURL("https://api.twitter.com/oauth/access_token")
         .withConsumerSecret("twitterConsumerSecret")
         .withTokenSecret("your_oauth_token_secret")
         .withParameter("oauth_consumer_key", "your_consumer_key")
         .withParameter("oauth_token", "your_oauth_token")
         .build()
