It terminates the execution of a loop, usuallly after a certain condition is satisfied.
What does this code return?
int i = 0;
int[] n1 = {1, 4, 6, 5};
n1[2] = 8;
n1[1] = 6;

A) 0
B) 1
C) 2
D) 5
What is D?

(Use int[] arr as the object for your answer)
for(int i = 0; (your code); i++)
What is (i <= arr.length - 1) OR (i < arr.length)
Jack wants to make an array that holds all of his books. Each value of the array would hold the title of a book.

How could Jack change his library books in the array when he returns them?
books[index of library book] = (new book as a String)
