What about a regular queue, of Objects of type PrinterJob (or something), each PrinterJob contains the the info.

public class PrinterQueue{
protected Vector jobs = new Vector(DEFAULT_LENGTH);

public int getSize(){
return jobs.size();
}

public void addJob(PrinterJob pj){
jobs.add(pj);
}

public PritnerJob removeNext(){
   return deleteJob(0);
}

public PritnerJob deleteJob(int jobId){
   return (PrinterJob) jobs.remove(jobId);
}

public boolean isEmpty(){
   return getSize() > 0 ? false : true;
}
}

Then in PrinterJob:

public class PrinterJob{
protected String docName;
...
public String getDocName(){
return docName;
}
}

That any help?

GR.

(NOTE: that code i wrote off the top of my head, so it will need a little work to compile).

You could just extends java.util.Stack. It pretty much offers the required functionality.
