Head pointer: For the implementation of queue, a block of contiguous cells reverse in the main memory which holds the queue at its projected maximum size. In this condition, the operations are performed at the both ends of the structure. Two memory cells are set aside the structure to use as pointer. The pointer that keeps track of the head of the queue in the structure is called head pointer. Tail pointer: The pointer that keeps track of the tail of the queue in the structure is called tail pointer.

Chapter 8.3, Problem 8QE

Program Plan Intro

Head pointer:

For the implementation of queue, a block of contiguous cells reverse in the main memory which holds the queue at its projected maximum size. In this condition, the operations are performed at the both ends of the structure.

Two memory cells are set aside the structure to use as pointer. The pointer that keeps track of the head of the queue in the structure is called head pointer.

Tail pointer:

The pointer that keeps track of the tail of the queue in the structure is called tail pointer.

Java Graphics (Bonus In this lab, we'll be practicing what we learned about GUIs, and Mouse events. You will need to implement the following: A GUI with a drawing panel. We can click in this panel, and you will capture those clicks as a Point (see java.awt.Point) in a PointCollection class (you need to build this). The points need to be represented by circles. Below the drawing panel, you will need 5 buttons: O о о ○ An input button to register your mouse to the drawing panel. A show button to paint the points in your collection on the drawing panel. A button to shift all the points to the left by 50 pixels. The x position of the points is not allowed to go below zero. Another button to shift all the points to the right 50 pixels. " The x position of the points cannot go further than the You can implement this GUI in any way you choose. I suggest using the BorderLayout for a panel containing the buttons, and a GridLayout to hold the drawing panel and button panels. Regardless of how…
