Question 1.
What happens if a non-serializable object exists in an object graph?
Show hintHide hint
Think about what will happen if the Java serialization process encounters an object it can't handle.
Question 2.
What does an object graph represent?
Show hintHide hint
Consider how objects relate to one another in programming.
3Question 3.
What is an Object Graph?
- A single object
- Collection of interconnected objects
- An array of objects
Show hintHide hint
Consider how objects are related to each other.
4Question 4.
True or False: If an object graph contains cycles, serialization will fail.
- True
- False
Show hintHide hint
Recall how Java tracks serialized objects.
Question 5.
Create an object graph where Class A contains a reference to Class B and Class B contains a reference back to Class A. Explain how Java would handle serialization of this graph.
Show hintHide hint
Consider how cyclic references are tracked.
Question 6.
Design a scenario where you have multiple objects, some of which don’t implement Serializable. Discuss what errors you'd expect when trying to serialize this scenario.
Show hintHide hint
