In Python

1. Suppose myCar is the name of a class variable that references an object, and go is the name of a method. (The go method does not take any arguments.) writed a pseudocode statement that uses the myCar variable to call the method.

2. Look at this partial class definition, and then follow the subsequent instructions:

Class Book Private String title Private String author Private String publisher Private Integer copiesSold End Class 

• Writed a constructor for this class. The constructor should accept an argument for each of the fields.
• Writed accessor and mutator methods for each field.
• Draw a UML diagram for the class, including the methods you have written.

3. Look at the following description of a problem domain:

The bank offers the following types of accounts to its customers: savings accounts, checking accounts, and money market accounts. Customers are allowed to deposit money into an account (thereby increasing its balance), withdraw money from an account (thereby decreasing its balance), and earn interest on the account. Each account has an interest rate.

Assume that you are writing a program that will calculate the amount of interest earned for a bank account.

• Identify the potential classes in this problem domain.
• Refine the list to include only the necessary class or classes for this problem.
• Identify the responsibilities of the class or classes.

4. In pseudocode, write the first line of the definition for a Poodle class. The class should extend the Dog class.

5. Look at the following pseudocode class definitions:

Class Plant Public Module message() Display "I'm a plant." End Module End Class Class Tree Extends Plant Public Module message() Display "I'm a tree." End Module End Class 

• Given these class definitions, what will the following pseudocode display?

Declare Plant p Set p = New Tree() Call p.message()
