Print queue solution approach

(light music)…- [Instructor] Now I'll share the approach I took to solve…the queues challenge.…For the PrintQueue class, I made that identical…to the data structure we created in our queue chapter.…I knew that the job class should have information…about how many pages are left in the job.…If I printed a page from the job,…I decremented the page count.…When the job got to a point where it had zero pages,…I knew that printing was complete.…As for the printer class, I knew it should carry…information about the job that it was working on,…I also knew that I was going to have to figure out how…to make the classes talk to each other because the printer…needed to get the next job by dequeueing from a non-empty…PrintQueue object.…

Another example of how I needed to get the classes…to talk to each other was that I knew I would need…to use job.print_page and job.check_complete…within my printer class.…Let's take a look at the code I wrote to make…all of this happen.…
