Hi All,

I am preparing for OCP on Java 8 and reading the book by Jeanne, the following program hangs after printing the first System.out.println


Only Hello world is printed and the prgram hangs for hours. I have to force close. Could any please help

You have to call service.shutdown(). See page 337 of the book for the explanation.

The example you quoted was a code snippet so we didn't call shutdown to call more attention to the "main" code.
