Selected Answer: BCG

The correct answer is BCG B - The variable "amount" in Class CheckingAccount is public, which allows the change from the instance to the main method C - method setAmount () when called from the instance in the main method allows to modify the variable "amount" in the instance of CheckingAccount G - The changeAmount () method receives in input the same value present in the CheckingAccount instance but in negative. Being public, the variable does not generate an error.
