private Node test(String symbol)
    {

        Node retval = null;
        Node node1 = portfolio;
        do
        {
            if(node1.next == null)
                break;
            if(((Stock)node1.item).getSymbol().equals(symbol))
            {
                retval = node1;
                break;
            }
            node1 = node1.next;
        } while(true);
        return retval;
    }

 

I was studying some code and had a question which I couldn't find the answer to.

 

This is the line...

 

while(true);

 

While what is true is it executing the code? Thank you!

Never mind, sorry!

 

It seems it just keeps checking the nodes and increments the nodes one by one and breaks eventually.

 

Am I right?

The do...while loop in the above code is an infinite loop - it will execute indefinitely, unless it is explicitly broken out of with a break statement. So yes, that loop will run until either of the two if statements evaluate to true.

 

I've never done any java, but i would guess that the function searches some sort of list structure.

Well, since all that a while does is check if a condition evaluates to boolean true and then executes a block if it does, putting true as the condition is guaranteed to run the loop infinitely unless explicitly broken out of.  while(1) would do the same thing.
