can someone give me a simple explaination  of what a PriorityQueue actually does? 

would you prefer this:

    public Product getProduct() {
        if(!fragile.empty()) {
            return fragile.pop();
        } else if(!normal.empty()) {
            return normal.pop();
        } else if(!heavy.empty()) {
            return heavy.pop();
        }
        return null;
    }

thanks.  that code works just fine.

pscode.com is perfect.   thanks!

i'm trying to test 3 stacks.  below is a method that test only 1 stack.  can anyone help me code this method in order for it to test all 3 stacks?

private Stack<Product> fragile;
private Stack<Product> normal;
private Stack<Product> heavy;
.

public Product getProduct() {
       
    if(fragile.empty()) {
            return null;
    } else {
            return fragile.pop();
    }
}

im not talking about the API files......i was wanting to see some actual JAVA code to compare.  most of my searches bring back API's.

are there any websites i can referance that provide JAVA code?  for example, i'm trying to learn how to use the Collection Interface and program my own class implimenting the methods.
