14.7. Synchronization

Try these first

1. 1.

   What is synchronization?

   Hint

   Think about why we need to control access among threads.

2. 2.

   What is a synchronized method?

   Hint

   Recall how we declare such methods in Java.

3. 3.

   What is the main purpose of synchronization in multithreading?

   • To speed up execution
   • To ensure data consistency
   • To allocate more memory

   Hint

   Think about what synchronization protects.

4. 4.

   True or False: A synchronized method locks the entire method, preventing any other threads from executing it simultaneously.

   • True
   • False

   Hint

   Remember what happens when one thread hits a synchronized method.

5. 5.

   Implement a Java program with a shared counter variable that multiple threads access. Use both synchronized methods and synchronized blocks to demonstrate their use in maintaining data integrity.

   Hint

   Focus on how to structure your class for clarity and thread safety.

6. 6.

   Analyze a scenario where an application suffers from race conditions due to improper synchronization. Suggest a code solution that employs synchronized methods to resolve the issue.

   Hint

   Think about what specific variables are shared and need protection.
