Modifier-changes one or more values of the class

6)

Constructor- called once the object is created.

7)

Code that is executed outside class must be invoked by object reference followed by a dot and field name.

8)

Bank_Acct my_Acct;

This is where an object is created to the class Bank_Acct. When an object is created, the constructor is automatically invoked. In the constructor, the account balance is set to 0.
