Challenge Problems
Push your limits with challenges.
Question 1
Consider a multithreaded application where two threads are updating a shared boolean variable without synchronization. Describe potential outcomes and how you would apply the JMM principles to avoid issues.
💡 Hint: Focus on how updates to shared variables can affect execution.
Question 2
Write code demonstrating improper usage of shared variables resulting in race conditions. Then, modify the code to ensure thread safety using the principles of the Java Memory Model.
💡 Hint: Think about how thread synchronization can control access to shared resources.
