A thread goes through various states in its lifecycle, from creation until its termination. Understanding the lifecycle of a thread is crucial for managing concurrent operations and optimizing the performance of multi-threaded applications. The lifecycle of a thread typically involves the following states:

New: This is the phase where a thread is created but hasn’t started running. At this point, the thread is considered not alive.

Runnable: The thread is ready to run and is waiting for the CPU’s attention. Proper management of runnable threads ensures no thread has to wait too long, enabling faster results.

Running: The thread is executing its tasks. This state allows multiple threads to operate simultaneously, reducing overall processing time. The thread can move out of the Running state for various reasons, such as waiting for resources or yielding control to another thread.

Blocked/Waiting: The thread is in a waiting state; it is waiting on other threads to complete their tasks or some external actions.

Terminated: The thread has completed its tasks and exited. Managing this state well is essential for freeing up system resources.
