I am new to concurrent coding and trying to implement simple ThreadPool by myself. I found this implementation on a learning website(jenkov.com) and it seems to be working fine. However, I think thread and isStopped should be atleast volatile in PoolThreadRunnable class or Atomic variables as they are shared by two threads, the one running the method on the object(where isStopped=true and this.thread.interrupt() is called) and the one in which actual run code is being run(where we do this.thread=Thread.currentThread() and while(!isStopped()). Is my understanding correct or am I missing something?

Below is the sample code, the count value is not matching sometimes when x.var value is “menu” and I am appending value of count in my data. In most of the cases the value is same, but sometimes the value seems to be mismatching. Is there any issue with code

I’m currently learning about multithreading in Java and encountered an interesting behavior that I’m struggling to understand. I have a simple Java program that utilizes multithreading to increment a counter, but I’m getting inconsistent output based on the placement of print statements in the code.
