I read that thread priorities may not ensure that your program would run with the same path as the thread priorities
But in the long run(with time), priorities does take effect?

I read this thread

The main thing to remember is that with multiple threads you've got very little control over the scheduling (unless you intervene with synchronized blocks or other mechanisms). The priorities are just a hint to the scheduler, but they may or may not have a great effect. In fact, you can potentially get very different results running the program twice with the same priorities.

The key thing to take away from this is to never make assumptions over how the threads will be handled when left to their own devices. If the order really matters to your application, you need to design that in.

I wrote this code

When I see the output its different everytime(even if we ignore the if loops)
Now my question is lets say a scenario
where three threads are downloading different files of size 2, 8 and 20 MB
I want the logic that the thread downloading the smallest file should get more priority
Is above logic the right way to implement the same?
Don't get me started about those stupid light bulbs.
