Chapter 16. Threads
In this chapter you'll investigate the facilities Java has that enable you to overlap the execution of segments of a single program. As well as ensuring your programs run more efficiently, this capability is particularly useful when your program must, of necessity, do a number of things at the same time: for example, a server program on a network that needs to communicate with multiple clients. As you'll see in Chapter 18, threads are also fundamental to any Java application that uses a graphical user interface (GUI), so it's essential that you understand how threads work.
In this chapter you'll learn:
What a thread is and how to create threads in your programs
How to control interactions between threads
What synchronization means and how to apply it in your code
What deadlocks are and how to avoid them
How to set thread priorities
How to get information about the threads in your programs
