🔍 The Three Java Threading Concepts That Quietly Break Production Code
Most concurrency bugs don't come from big architectural mistakes. They come from small misunderstandings about how threads actually behave underneath.
⚡ Thread Priorities
We think higher priority means faster execution. But in reality, it’s just a hint to the OS scheduler
👁️ Visibility & the volatile Keyword
Multiple threads don’t always see the latest value of a variable. Each core can cache its own copy — leading to stale reads and confusing behavior.
🔒 Atomicity
Even a simple count++ isn’t atomic. When several threads update the same variable, values are lost or overwritten. Atomic classes ensure updates happen safely, without corrupting shared data.
If you want a clear, visual explanation of how all three work (with demos and diagrams), I’ve broken them down here:
