Anew class is proposed to collect information about a group of dvds. a separate class containing information about a single dvd, named dvd, has already been created. which of the following is the best design to store the data and size of this collection? a) have an arraylist of dvds and use its size as the size of the collection. b) have an arraylist of dvds and an integer representing the number of dvds in the collection. c) have an array of dvds and use its size as the size of the collection. d) have a single dvd variable representing the last dvd added and an integer representing the number of dvds in the collection.

Through the process of sedimentation,sediment is turned back to rock to form sedimentation.the process of sedimentation is: > deposition-where fragments were deposited into the river or sea under gravity or travelling agent such as wind or water. > sedimentation-the fragments deposited in the river sedimented and accumulate> compaction-the layers of fragments deposited undergoes compaction due to the weight if the upper layers> cementation-chemical substance of the fragments such as cement dissolved into the water and cement the other fragments together to form sedimentary rock.thus,cementation and compaction are the process.on the other hand, transformation only occur when a rock under goes metamorphism(compaction or extreme heat).while recrystillization occurs when a rock is melted and cooled down,which also requires metamorphism to take place.hope it !

In which career field, would the computing technology industry association's comptia a+ certification be useful?
