Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Create a Java program that simulates a scenario where multiple threads attempt to modify a shared counter variable without synchronization. Show the results and explain the resultant behavior.

💡 Hint: Focus on how threads access the same variable simultaneously.

Challenge 2 Hard

Discuss how the use of synchronized can lead to performance bottlenecks in large-scale applications. Provide a hypothetical scenario where this might occur.

💡 Hint: Consider high-traffic situations and the load involved.
