coinpurse's Issues

MoneyFactory shouldn't read and set its instance

MoneyFactory shouldn't read the ResourceBundle (purse.properties), instead you should provide setMoneyFactory(MoneyFactor) for other class to set the Factory.

Moreover, if MoneyFactory read the bundle and set the factory on its own, setting the new factory on the fly is impossible (or you may have to edit the bundle file and load it again).

removing monetary objects in Purse.withdraw can be simplify

for (Valuable tem : templist) {
    for (int i = 0; i < count(); i++) {
        if (tem.equals(this.money.get(i))) {
            this.balance -= this.money.get(i).getValue();
            this.money.remove(i);
            break;
        }
    }
}

For now, the process of removing monetary objects is seems to be over complicated. I suggest that you read this method List.remove(Object o)
