Answer 1

The simplest way is initialize firebase app:

    InputStream serviceAccount = new FileInputStream(SERVICE_ACCOUNT_KEY);
    GoogleCredentials credentials = GoogleCredentials.fromStream(serviceAccount);
    FirebaseOptions options = new FirebaseOptions.Builder()
            .setCredentials(credentials)
            .build();

    FirebaseApp.initializeApp(options);

and then you can run firestore database

    Firestore db = FirestoreClient.getFirestore();

    ApiFuture<QuerySnapshot> query = db.collection(YOUR_COLLECTION_NAME).get();
    QuerySnapshot querySnapshot = query.get();
    List<QueryDocumentSnapshot> documents = querySnapshot.getDocuments();

I think that it will be helpfull https://firebase.google.com/docs/guides
