18.6. Multi-threaded Server Programming

Try these first

1. 1.

   What does a ServerSocket do?

   Hint

   Think about how a phone line works to receive calls.

2. 2.

   What method do we override in a thread?

   Hint

   It's the method that contains the code to execute in the thread.

3. 3.

   What is the main advantage of multi-threaded server programming?

   • It improves client security.
   • It allows multiple clients to be served simultaneously.
   • It reduces server costs.

   Hint

   Think about how busy servers manage many requests at the same time.

4. 4.

   True or False: Each instance of ClientHandler runs on the main server thread.

   • True
   • False

   Hint

   Consider how having guests in different rooms means they can have separate conversations.

5. 5.

   Design a multi-threaded server that can handle a simple request queue. Explain how clients will queue their requests and be handled by separate threads.

   Hint

   Think about how you would manage what customers enter a store based on their order of arrival.

6. 6.

   Critique a simple multi-threaded server implementation and identify potential race conditions. Suggest improvements.

   Hint

   Consider how traffic regulation could help prevent accidents at busy intersections.
