Chapter 14: Multiple threads

Java provides a built-in facility to support multiple concurrent subtasks, called
threads, running within a single program. (Unless you have multiple processors on
your machine, this is only the appearance of multiple subtasks.) Although these can
be used anywhere, threads are most powerful when trying to create a responsive
user interface so, for example, a user isn’t prevented from pressing a button or
entering data while some processing is going on. This chapter looks at the syntax
and semantics of multithreading in Java.
