Java Threads vs Virtual Threads vs Kotlin Coroutines: Performance Comparison with Real Tests

In this video, we dive deep into a practical performance comparison between Java threads, virtual threads, and Kotlin coroutines. We conduct three real-world tests:

- A simple runnable that waits for 5 seconds.
- A runnable that duplicates an array of 1,000,000 integers.
- A runnable that finds palindromic numbers in an array of 10,000 integers.

Each test highlights key differences in execution and performance across Java threads, virtual threads, and Kotlin coroutines. Watch to understand how these threading models handle computational and I/O-bound tasks, and which approach might be optimal for your Java or Kotlin projects!
