Question about PriorityQueue

[Fred Victa]

Is the following code supposed to place all of the integers in numerical order? If not, can anyone explain why?

public class myClass{


public static void main(String[] args)
{

PriorityQueue<Integer> x = new PriorityQueue<Integer>();
x.add(2);
x.add(66);
x.add(23);
x.add(1);
x.add(3);
System.out.println(x);
}

}

[Stephan van Hulst]

So what does the program output? Does it match you expectations? Did you read the class documentation?
