Challenge Problems
Push your limits with challenges.
Question 1
Design a simple multithreaded application that demonstrates the effects of instruction reordering. Describe any issues experienced when executing the program without using any synchronization.
💡 Hint: Don't forget to consider what could happen with multiple threads accessing shared data.
Question 2
Consider the implications of using volatile vs. synchronized blocks for a shared counter. Write a sample code comparing both implementations and analyze their behavior under multithreading.
💡 Hint: Look carefully at how data is accessed and changed in each case.
