I don't know of any specific pattern, but the logical way would be to
create a single class that encapsulates the running of the thread AND
the result, e.g.

class abstract ThreadWithResult extends Thread {
 private boolean finished=false;
 private Object result=null;
 public Object getResult() throws IllegalStateException{
  if(finished)throw new IllegalStateException("Process incomplete");
  return result;
 }
 public void run(){
  ...
  result=...;
  finished=true;
 }
}

then
{
 ThreadWithResult t=new ThreadWithResult();
 t.start();
 t.join();
 Object r=t.getResult();
}

But there could be a more elegant way using synchronised
methods...?
