Transcribed Image Text:Question 6
Which of the following statements are true. Select all that apply. You may assume
each is independent.
O$ git checkout 750a58f
$ git branch example
will move HEAD to 750a58f.
O$ git branch -v
will list fcc756f next to master.
O$ git checkout -b example
will create and checkout a branch with fcc756f as its most recent commit.

Question 7
A StringList implementation can contain null items and empty strings.
True
O False
Question 8 (1 point)
The out of bounds / range criteria for the methods in StringList differ depending
on their function / purpose and the supplied value for their index parameter. Match
each of the methods below to its corresponding out of bounds criteria.
1.
(index <0|| index > size())
hnolean ada(irt, intex, Strirs s)
2.
(index <0 || index = size (0)
String reuove (Int index)
3. (index >= 0 kà index size())
String ee:(int index)
4.
(index >= 0 ke index < size (0)
Question 9
Suppose that you have a reference to a newly created object of a class that properly
implements the stringList interface, including the extra credit requirements.
Further suppose that reference is stored in a variable called myList and the
following valid code snippet is executed within a method:
myList.add (0, "a");
myList.add (1, "b");
myList.add (2, "c");
Which of the following code snippets will produce the output below if executed
within the method directly following the snippet above?
$a b c!
String out - ylist. akeString("S", _", "!").
Systen at. printin(out):
U Systen Jul. Br intln("s__e ").
UStrine aut = yList. nakeStrine"_")
Systen Jut. pr intin("" - vut - "!")
![Question 3
Which of the following code snippets will successfully output the third string in a list
of nodes? Assume that the reference to the first node (containing the first string) in
the list is named head.
]int counter
= 0;
while (counter < 2) (
head = head.getNext ();
counter+t;
} // while
System.out.println (head.getItem ());
Ohead = head.getNext (). getNext ();
System.out.println (head.getItem () );
Ohead = head.getNext ();
head = head.getNext ();
head = head.getNext ();
System.out.println (head.getItem());
;
O head - head.getNext () ;
Node n = head.getNext ();
System.out.println (n.getItem ());

Question 4
Which of the following statements are true? Assume each statement is independent.
Select all that apply.
Os git commit -m "added contribution list"
will commit the changes made to CONTRIB. md, README.md, and NOTES.md to
the local repository.
O$ git add NOTES.md
will add NOTES.md to the stage and commit its changes to the repository.
O$ git log --pretty format: "&h - San, tar : s"
will print the log, formatted to contain the abbreviated commit hash, author
name, relative author date, and commit subject.
O$ git reset HEAD NOTES.md
will make Git not include the changes made to NOTES.md in the next commit.

Match each description below with its corresponding commit. Note: any commits
made before a branch was created are still considered part of that branch's history.
For example, all branches have the first overall commit as part of their history - even
