The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

I'm lost with this coding project

Asked by javalurnin in Miscellaneous Programming, Java Programming Language, New to Java Programming

Tags: , ,

I am so lost.  I have to write a heap-based priority queue for class and I guess I'm fortunate enough to have a teacher that refuses to teach us how to use any code. (LOL)
We were just given a UML and told "see if we can do it"
Any advice on where to start or is there any code out there that's already written with similar functions and classes so I can see how this works? And mostly how my teacher wants it to work...Start Free Trial

MyPriorityQueue extends MyMinHeap
 
 
+ MyPriorityQueue () // creates an empty priority queue
+ MyPriorityQueue (in arr : Comparable [], in n: int) //creates a priority queue out of an array of Objects
+ enqueue(in o: Comparable) : boolean //adds a new student to the queue return false if there's no more
room
+ dequeue() : Object // removes the next Object in the queue or null if the queue is empty
 
 
MyMinHeap
 
 
 
- theHeap: Comparable []
- size : int
+ MyMinHeap ()
+ MyMinHeap (in arr : Comparable [], in n: int)
+ getSize() : int
+ add (in o: Comparable) : boolean
+ removeMin () : Object
- shiftDown (in index : int) : void
- buildHeap () : void
+ parseInts() : void // shows the contents of the Heap assuming it holds elements of type Integer
+ parseStrings(): void // shows the contents of the Heap assuming it holds Strings
Obviously, you may add any additional function you might feel is needed.
