How do i sort a priority queue by the priority ???

[markhazlett9]

Like what are talking about priority queue? like the system queue? or a queue you have set up?

[pansylea]

i have 4 classes and a tester

-Task
(String taskDescription, String taskCategory, int taskUrgency, String taskDay, String taskMonth, int taskYear)
This class implements Comparable and has the following methods
get() and sets()
compareTo()
toString()


- ArrayStack
This class has the following methods
push()
pop()
peek()
isEmpty()
isFull()
toString()
length()

-PriorityQueue
This class has these methods
insert()
remove()
peek()
isEmpty()
isFull()
toString()
length()

Then the tester creates an array stack and fills it with tasks. it then searches for tasks to be completed today and is meant to be inserted into the priority queue. The most urgent task is then meant to be displayed and the priority queue is to be sorted by urgency.

Your PriorityQueue class needs to implement the Comparable interface: Comparable

Note Java has a PriorityQueue class: PriorityQueue
