As @ReazMurshed said, you're almost there. But you're failing to iterate over one level in your tree. It seems that ref is pointing to the subscriptions node in your JSON. Under that you have users and then you have the push ids. So you'll need to do a double loop:

ref.addListenerForSingleValueEvent(new ValueEventListener) {
  public void onDataChange(DataSnapshot snapshot) {
    if (dataSnapshot.exists()) {
      for (DataSnapshot userSnapshot : snapshot.getChildren()) {
        for (DataSnapshot programSnapshot : userSnapshot.getChildren()) {
          Program program = programSnapshot.getValue(Program.class);
      }
    }
  }

  public void onCancelled(FirebaseError firebaseError) {

  }
});
