Creates a new
PriorityQueue

of the size of
coll
to allow for some growth without resizing.
This queue will be ordered the same way as
coll
.
public
PriorityQueue(PriorityQueue<? extends E> coll)
Creates a new
PriorityQueue
whose initial contents are the
contents of
coll
. The capacity of the queue is initially 110%
of the size of
coll
to allow for some growth without resizing.
This queue will be ordered the same way as
coll
.
Since
PriorityQueue
does not accept
null
elements, all constructors
that take collections throw
NullPointerException
if a
null
element is en-
countered.
The comparator used to construct the priority queue can be retrieved
with the
comparator
method. This has the same contract as the
comparator
method in
SortedSet
, returning
null
if the elements' natural ordering is
being used.
