How to retrieve Firebase data in a (non Android) Java app?

Is there a way to retrieve data from Firebase to a Java application ?

I have an Android application which stores the data in to a Firebase database and I need to read that data in a Java application. I searched over the Internet, but I have not found a clear answer.

//not the URL from browser, the one above the database

FirebaseOptions options = new FirebaseOptions.Builder()
.setDatabaseUrl("https://database-ff395.firebaseio.com/")
.setServiceAccount(new
FileInputStream("C:/Users/Denisa/Desktop/database-2aab74679b79.json"))
.build();
FirebaseApp.initializeApp(options);

DatabaseReference ref = FirebaseDatabase
.getInstance()
.getReference("restricted_access/secret_document");


//here I try to reference the database and put a value in it

final FirebaseDatabase database = FirebaseDatabase.getInstance();
DatabaseReference ref1 = database.getReferenceFromUrl("https://database-ff395.firebaseio.com/database-ff395");
ref1.setValue("ooo");

Answer

Accessing the Firebase Database from a regular (non-Android) JVM is considered a server platform by the Firebase documentation. You can find all about it in the Firebase documentation for its server SDKs.
