Questions are all related to Basic Card lab.

1. Draw the detailed UML class diagram of the class Card.

2. Draw the detailed UML class diagram of the class BasicCardFrame.

3. List all Java library classes that BasicCardFrame class aggregates. How are they imported into the program?

4. The BasicCardFrame class imported the entire package of java.util. Is it really necessary? Can you replace it by importing a single class instead?

5. Which of the program files of the lab is an application? How can you tell?

6. If you want to put all classes you defined in Basic Cad lab in a package named myBasicCard, what changes you must make? Also draw the conceptual level diagram showing the package and the classes in it.

public String toString(){
