The Bloch builder is specifically for creating only one class of objects.

• Yep

• Nope

Which of these must builders abstract?

• The process of construction

• The object constructed

• The families of objects constructed

• The object duplication process

​Which of these does the GoF builder pattern make use of that the Bloch builder doesn't?

• A builder interface

• Incomplete object hiding

• A separate class from the object

• Step-by-step construction methods

Builders of the same interface cannot create objects of different interfaces.

• True

• False

Choose the odd pattern out, based on category.

• Template Method

• Abstract Factory

• Singleton

• Builder

Both the Bloch builder and the GoF builder can create immutable objects.

• Yah

• Nah

Choose the patterns that can be created with a Builder, according to the lecture.

• Composite

In the lecture, it was mentioned that a principle in SOLID can be satisfied when using Builder.

Which was mentioned?

• S

• O

• L

• I

• D

Choose all which is true about directors.

• Contains reusable construction routines

• Accesses concrete builders directly

• Not always needed in the program

• Receives a builder instance instead of creating directly

Choose all that both the Bloch builder and the GoF builder can do.

• Provide currying (method chaining)

• Get rid of unwieldy constructors

• Allow choosing the order of the steps

• Hide incomplete objects
