process thread

Thread Lifecycle

A thread's lifecycle is similar to a process but occurs within the context of its parent process. Threads transition through New, Runnable, Running, Blocked/Waiting, and Terminated states. Key differences include that threads can be in a timed-waiting state (sleeping for a specified duration) and that thread termination must be coordinated to avoid leaving shared resources in an inconsistent state.

Use Cases

  • •Managing thread pool workers that cycle between idle (waiting) and active (running) states
  • •Implementing cancellation tokens so threads can terminate gracefully mid-task
  • •Debugging deadlocks by inspecting which threads are stuck in the blocked state
  • •Coordinating thread join operations to wait for background work before shutdown
