Search Console API , Query Java implementation (Google WebMaster)

i am using web Search Console API (Google WebMaster tools api) to query data , i am using the pyton implementation ,i need to use the java implementation instead , but i did not found any example in java using query.

this is the python code that i need to replace: pyton code :

request = {
      'startDate': flags.start_date,
      'endDate': flags.end_date,
      'dimensions': ['date']
  }
response = execute_request(service, flags.property_uri, request)
print_table(response['rows'], 'Available dates')  

i found this java class com.google.api.services.webmasters.Webmasters.Searchanalytics.Query but i don't know how to use it, i did not found any examples of it

any help would be appreciated thank you in advance.
