Question

assume that an arraylist named arr has been created and it contains a large number of elements. write a statement that assigns the next to last element of the arraylist to the variable x, which has already been declared.

Answer 1

To assign the next to last element of an ArrayList named arr to a variable x, use x = arr.get(arr.size() - 2);. This code uses the get method to access the second to last element of the ArrayList.

Step-by-step explanation:

To assign the next to last element of an ArrayList named arr to a variable x, you can use the following statement:

x = arr.get(arr.size() - 2);

This line of code utilizes the get method of the ArrayList to access the element at a specific index. Since indexes in ArrayLists are zero-based, arr.size() - 1 would give you the last element, so arr.size() - 2 gives you the next to last element.
