I have written query using kotlin. But it will help you

    val query = FirebaseDatabase.getInstance()
        .getReference()  
        .child("Developers")  
        .orderByChild("dcountry")
        .equalTo("france")
        .limitToFirst(50)

You can do this:

MyFirebase.db.child("Developers").orderByChild("dcountry").equalTo("France").addValueEventListener(object:ValueEventListener{

which will give you all countries that are equal to france
