I'm puzzled with the behaviour of the PriorityQueue. The executing the following code

prints out [0, 1, 2, 7, 5, 9, 3]

In the SUN API Definition, it says

An unbounded priority queue based on a priority heap. This queue orders elements according to an order specified at construction time, which is specified either according to their natural order (see Comparable), or according to a Comparator, depending on which constructor is used.



But why is the above not sorted according to the natural order? Or is it just the way the toString works?

BTW - changing it to String also results in the same.

This is the natural order only.

Oh Ok. Thanks Ankit. I wonder why sun didn't mention this clearly.

BTW - I did search for Priority queue before posting a new thread and didn't find these threads!
