1.
Where is the error located in the stack trace?
In the main function
In the test file
In the database module
In the user interface
Explanation:
James says, “The error is in the main function.”
2.
What kind of error does Anna identify in the stack trace?
A syntax error
A network timeout
A null pointer exception
A permission error
Explanation:
Anna says, “it shows a null pointer exception.”
3.
What does James discover about the variable?
It is not initialized
It is only used in testing
It is deleted too early
It is assigned twice
Explanation:
James says, “the variable is not initialized.”
4.
Why does Anna say that the variable not being initialized is the root cause?
Because the stack trace shows the variable is wrong in every file
Because testing already proved the code works
Because the main function should never use variables
Because an uninitialized variable can lead to the crash they saw
Explanation:
The conversation shows the error is a null pointer exception caused by a variable that was not initialized, which supports Anna’s conclusion that this is the root cause.
5.
What will they do after fixing the code?
Test the program again
Ignore the error and continue
Rewrite the main function completely
Delete the stack trace
Explanation:
Anna says, “After fixing, we need to test again,” and James agrees that testing will make sure the error is gone.
