3.1.PriorityQueuewithComparablefor Natural Ordering To create a priority queue, use one of the following constructors: PriorityQueue(): creates an instance with the default initial capacity (11) with elements sorted by natural ordering. PriorityQueue(capacity): creates an instance with the specified in...
* @param initialCapacity the initial capacity for this priority queue * @param comparator the comparator that will be used to order this * priority queue. If {@code null}, the {@linkplain Comparable * natural ordering} of the elements will be used. * @throws IllegalArgumentException if {@c...
However, this comparator is a little lame. It obviously works brilliantly for PriorityQueues of type String, but in case of (say) Integers, not quite (It would think 5 is greater than 49). Another approach would be to force the user to provide a comparator - but I know that Java Util...

I am trying to learn about custom comparators in priority queue. however, i am unable to get the expected behaviour. I have wrote two custom comparators in the below code one for a vector and the other for a priority queue and the logic is same for both the comparators. how the output...

I am looking to Submit runnable tasks for execution with this priority value and I am not sure where to implement this logic and how to do it. I know I have to use the PriorityBlockingQueue somewhere and implement a Comparator. So do I... 1) Implement in MyThreadPool class 2) O...
