PriorityQueue.enqueue(Object)
-
dequeueChar
char dequeueChar()
Dequeues the first element from the queue.- Returns:
- the dequeued element.
- Throws:
java.util.NoSuchElementException
- if the queue is empty.- See Also:
dequeue()
-
firstChar
char firstChar()

UnsupportedOperationException
.- Returns:
- the last element.
- Throws:
java.util.NoSuchElementException
- if the queue is empty.- See Also:
last()
-
comparator
CharComparator comparator()
Returns the comparator associated with this priority queue, or null if it uses its elements' natural ordering.- Specified by:
comparator
in interfacePriorityQueue<java.lang.Character>
- Returns:
- the comparator associated with this priority queue.
- See Also:
PriorityQueue.comparator()
- API Notes:
- Note that this specification strengthens the one given in
PriorityQueue.comparator()
.
