<h2>Question:</h2>

The remove() method in the Queue interface ________.

A. retrieves, but does not remove, the head of this queue, returning null if this queue is empty

B. retrieves and removes the head of this queue, or null if this queue is empty

C. retrieves, but does not remove, the head of this queue, throwing an exception if this queue is empty

D. retrieves and removes the head of this queue and throws an exception if this queue is empty

<h2>Answer:</h2>

D. retrieves and removes the head of this queue and throws an exception if this queue is empty

<h2>Explanation:</h2>

In Java, the Queue interface is found in the java.util package and inherits from the Collection interface. It is used to store elements which are processed in the order in which they are inserted. This means that the first element will be processed first.

The Queue interface has many methods. Some of them are;

i. add(): allows elements to be added to the queue.

ii. remove(): retrieves and removes elements from the head of the queue. The head of the queue points to the first element of the queue. If the queue is empty, the remove() method throws an exception called the <em>NoSuchElementException</em>

<em />

iii. poll(): retrieves and removes the element at the head of the queue. Unlike the remove() method, if the queue is empty, a <em>null </em>is returned.

iv. peek(): retrieves but does not remove the element at the head of the queue. Just like the poll() method, a <em>null</em> is returned if the queue is empty.

The correction to the attached program

Some variables are not needed; so, I've removed the redundant variables.

The main error in the program is in the loop;

After the tuition for each year has been calculated, the startTuition of the next year must be set to the current tuition

Georgia [21]

These principles are not explicit to one kind of program and are increasingly broad "best practice" rules that assist designers with composing code that is easier to maintain.

<u>Explanation:</u>

A set of programming guidelines that are executed to play out a particular undertaking according to the prerequisites of the client is known as programming. Every product has some essential standards to follow. In light of all product frameworks have basic quality traits, including accessibility, modifiability, execution, security and wellbeing, testability and ease of use, the key programming thoughts give basic arrangements or strategies to help those characteristics.

It is generally less expensive, over the long haul, to utilize programming designing strategies and methods for programming frameworks instead of simply compose the projects as though it was an individual programming venture.
