A(n) ____ is an object that produces each element of a collection, such as a linked list, one element at a time.

dimaraw [331]

A collection of elements, such as a linked list, is produced one element at a time by an object known as an iterator.

<h3 /><h3>What is an iterator?</h3>

Java's collection framework uses iterators to fetch elements one at a time. It is a universal iterator since any collection object can use it. We can do both read and remove actions with the help of an iterator. It is an enhanced version of enumeration that now can remove an element. Every time we want to enumerate elements in any collection framework defined interfaces, such as Set, List, Queue, Deque, and any implemented classes of Map interface, we must use an iterator. The only cursor offered across the board by the collection framework is the iterator. Calling the iterator() function on the collection interface will provide an iterator object.

Ksivusya [100]

Answer:

$5,569,634

Explanation:

Current ratio = current assets = 2× $9,500,000= $19,000,000

Inventory turnover = 12 times = $65,000,000÷ 12= $ 5,416,667

Average collection period (APC) = 45 days = account receivable × 365 days

=> Account receivable = (45 × $65,000,000 )÷ 365 days = $8,013,699

=> cash and marketable securities =$ 19,000,000 - $5,416,667- $8,013,699 = $5,569,634

Zielflug [23.3K]

Answer:

She will have $16,772.59 more in the second investment.

Explanation:

Giving the following information:

Recently she received an inheritance of $54,000 from her grandmother's estate. She plans to use the money for the down payment on a home in ten years when she finishes her education.

We need to use the following formula:

FV= PV*(1+i)^n

First savings account:

FV= 54,000*(1+0.04)^10= $79,933.19

Second investment:

FV= 54,000*(1+0.06)^10= $96,705.78

She will have (96,705.78 - 79,933.19) $16,772.59 more in the second investment.
