Iteration, that waits?

Question

My company and a sister company have the same information stored in different places. We want some of the Data they have, and They want some of the data we have. Unfortunetly the data they have is not stored on a database, but in html, asp, webpages. So I know how to go to website and extract the data, put it into a variable and insert it into a db. The problem I have is when I get a project ID which is what the primary key is for them them and us. I need to iterate through a collection of Project IDs, only one at a time. Gather the information that I need. Insert it into the DB. and get the next project ID and do it again until done. I know how to iterate through a collection, but how do I iterate one at a time, and wait till I am done?
I would appreciate the help.

Answer 1

This is pretty straightforward, really:// Build the iterator that gives you project IDs
Iterator it = getListOfProjectIDs();
// Loop through it
while (it.hasNext()) {
  // Get a project ID from the iterator
  ProjectID id = (ProjectID) it.next();
  // Do something with that project ID
  doSomethingWith(id);
  // carry on to the next project ID
}No waiting here... unless I don't understand your question.
