How to create test plan and test suite in java code how can i do rest call while extracting from RQM via Java code?

I have urlconstructutil.class is there here all the rest url I am mention

for example :-

RQM_BASE_URL = "/service/com.ibm.rqm.integration.service.IIntegrationService/resources/"

 public static String constructTestCaseRetreivalUrl( final String serverUrl, final String projectName )
   {if (projectName != null)
      { final String baseUrl = serverUrl + RQM_BASE_URL + projectName + "/testcase";
         final UrlGenerator urlGenerator = new UrlGenerator( baseUrl );
         final String params = "fields=feed/entry/content/testcase/(id|content|title|owner|webId|remotescript|identifier|creationDate|updated|priority|state)";
         urlGenerator.setParameter( FIELDS, params );
         return urlGenerator.getUrl();
      }
      return null;
   }
