Consider the following method countNegatives, which searches an ArrayList of Integer objects and returns the number of elements in the list that are less than 0. public static int countNegatives(ArrayList arr){int count = 0; for (int j = 0; j < arr.size(); j++) // Line 4{if (arr.get(j) < 0){count++;}}return count;}
Which of the following best explains the impact to the countNegatives method when, in line 4, j < arr.size() is replaced with j <= arr.size() - 1 ?
A. It has no impact on the behavior of the method.
B. It causes the method to ignore the last element in arr.
C. It causes the method to throw an IndexOutOfBounds exception.
D. It reduces the size of arr by 1 and the last element will be removed.
E. It changes the number of times the loop executes, but all indexes in arr will still be accessed.
The ArrayList's current int element count is returned by the size() function. Size() gives zero if the ArrayList is empty. Get(int index); public Thus option A is correct.
What searches an ArrayList of Integer objects and returns?The method get, which we previously described, is documented as having an argument type of int and a return type of E. This means that when get is called on an object of type ArrayListInteger>, it returns an Integer; similarly. When it is called on an object of type ArrayListString>, it returns a String, and so on.
If the requested element is present in the list, it returns true. It is used to return the first instance of the provided element in this list at the supplied index, or -1 if the element is not present in the list.
Therefore, It has no impact on the behavior of the method.
