I have an exercise with Proton card system (to charge money).

Public void

chargeProtonCard(int toChargeAmount)

if (toChargeAmount > Depositaccount.getAccountSaldo())


Can the part before the get be explained?... the insight of the if formule itself, what it does I understand.

Its more where to get the elements including the if. For this I would appreciate some clear insight.

Thank you.
