Object oriented with java

 

This assignment is for you to gain hands-on experiences of our weekly (week 9) covered topics including Queue, Heap, and Priority Queue. In this assignment, you need to write Java programs that meet the following requirements:

=== Basic Requirements (100 ‘pts) ===

1) (50 ‘pts) Implement a MyQueue class that supports the following interfaces within O(1) time:

1.1) int size(); //return the total number of stored elements
1.2) boolean isEmpty(); //return if the queue is empty
1.3) void offer(E val); //enqueue an element val for generic type E
1.4) E poll(); //remove head and return the removed value, return null if isEmpty()
1.5) E peek(); //return head, return null if isEmpty()

2) (50 ‘pts) Based on our class demonstration of MinHeap implementation, write a MaxHeap class that at least supports all the queue interfaces stated above as in 1).

=== Bonus (20 ‘pts) ===

a) (10 ‘pts) In the above requirement 2) MaxHeap, can you implement a class method: heapify(E[] arr) that takes in an array input, and transfer that array into a max heap?

b) (10 ‘pts) Inspired by the above practices, now revisite Leetcode 912. Sort An Array, this time use heap sort to conquer this coding challenge. Make sure your submission passes all Leetcode test cases.

Portfolio Project

 You will respond to three separate prompts but prepare your paper as one research paper

1.Start your paper with an introductory paragraph.

2.Prompt 1 “Data Warehouse Architecture” (2-pages): Explain the major components of a data warehouse architecture, including the various forms of data transformations needed to prepare data for a data warehouse. Also, describe in your own words current key trends in data warehousing. 

3.Prompt 2 “Big Data” (2- pages): Describe your understanding of big data and give an example of how you’ve seen big data used either personally or professionally. In your view, what demands is big data placing on organizations and data management technology? 

4.Prompt 3 “Green Computing” (2 pages): IT Green Computing. The need for green computing is becoming more obvious considering the amount of power needed to drive our computers, servers, routers, switches, and data centers. Discuss ways in which organizations can make their data centers “green”. In your discussion, find an example of an organization that has already implemented IT green computing strategies successfully. Discuss that organization and share your link. 

5.Conclude your paper with a detailed conclusion section. 

The paper needs to be 8 pages long and 6 references. Be sure to use proper APA formatting and citations to avoid plagiarism.
