10.3.4. Multithreading (Optional, for autosave)

Try these first

1. 1.

   What is multithreading?

   Hint

   Think about how it allows tasks to run at the same time.

2. 2.

   What does the run method do in a thread?

   Hint

   Consider what happens when you start a thread.

3. 3.

   What is the main benefit of using multithreading in applications?

   • It makes programs faster
   • It allows multiple tasks to run at the same time
   • It saves memory
   • None of the above

   Hint

   Think of how tasks can run without waiting for each other.

4. 4.

   True or False: A thread can run independently of the main program.

   • True
   • False

   Hint

   Reflect on how background tasks function.

5. 5.

   Create a Java program that simulates an autosave feature for a notepad application, ensuring that it autosaves user input every 90 seconds. Handle potential exceptions that may occur during file writing.

   Hint

   Think about using `Thread.sleep(90000)` for your timing.

6. 6.

   Discuss how deadlock might occur in a multithreaded environment, specifically with an autosave feature, and suggest strategies to prevent it.

   Hint

   Consider the order in which resources are accessed.
