What if we do know what they are talking about, but we don't know how or where to start?

More specifically, create a folder called lesson3 in the same place that lesson1 and lesson2 are located on your computer.

For Programming Exercise 3.3 open BlueJ and create a project called bankAccountProject inside lesson3. Then create a class called BankAccount in that project. Add methods for depositing and withdrawing money and retrieving the balance in the account. Then create another class called BankAccountTester. Have its main method create a BankAccount object and test it as the exercise asks.

Do the same thing for Exercises 3.9 and 3.11 and Project 3.4. First create a project for each exercise, e.g., carProject, letterProject, and studentProject. In each one create the requested class. For E 3.9 you want a Car class; for E 3.11 you want a Letter class; for P 3.4 you want a Student class. Complete the exercises for those classes.
