Access.get_user_data (String username) serve per ottenere un oggetto di tipo Entry e all'interno ci sono idati dell'utente

Browse Source 
Access.replace_data(String username, Entry new_data) serve per scrivere nel database i nuovi dati dellutente dopo aver modificato loggetto Entry ottenuto con il metodo precedente.

Per settare un nuovo bilancio basta invocare il metodo setBalance(double value) sull'oggetto Entry ottenuto.
Per settare un nuovo acquisto fatto dell'utente bisogna prima chiamare getStorico() sull'oggetto entry che restituira un arraylist ed in seguito eseguire un add sull'arraylist per aggiungere un nuovo oggetto di tipo StoricoItem (questo conterrà la descrizione, il prezzo al momento dell'acquisto e la data)
