The System.out.println() method will call the toString() method of the account object, which will return a string representation of the object. Since the BankAccount class does not have its own implementation of toString() method, the default implementation provided by the Object class (from which all classes implicitly inherit) will be used, which displays the class name and memory address of the object. Therefore, the output would look something like "BankAccount@1abc123".
