How to implement transaction when sharing data between objects in java

Question

I have some simple application with a method for a transaction between 2 objects.

public void transfer(Account source, Account target, double amount) {

  // some balance checking

  source.setBalance(sourceBalance - amount);
  target.setBalance(targetBalance + amount);
}

How to implement transaction i.e. do rollback when some error happens for example in target.setBalance() method for some reasons? I know that in Spring I can use @Transactional annotation when I use jpa repository, but in my case I use objects. These objects stored in in-memory storage - Map<Long, Account>.
