dequeueChar

public char dequeueChar()

Description copied from interface: CharPriorityQueue

Dequeues the first element from the queue.

Specified by:

dequeueChar in interface CharPriorityQueue

Returns:

the dequeued element.

CharPriorityQueue.dequeue()

firstChar

public char firstChar()

Description copied from interface: CharPriorityQueue

Returns the first element of the queue.

comparator

public CharComparator comparator()

Description copied from interface: CharPriorityQueue

Returns the comparator associated with this priority queue, or null if it uses its elements' natural ordering.

Note that this specification strengthens the one given in PriorityQueue.comparator().

Specified by:
