What are the states in the lifecycle of a Thread?

A thread can have one of the following states during its lifetime:

1. New: In this state, a Thread class object is created using a new operator, but the thread is not alive. Thread doesn't start until we call the start() method.
2. Runnable: In this state, the thread is ready to run after calling the start() method. However, the thread is not yet selected by the thread scheduler.
3. Running: In this state, the thread scheduler picks the thread from the ready state, and the thread is running.
4. Waiting/Blocked: In this state, a thread is not running but still alive, or it is waiting for the other thread to finish.
5. Dead/Terminated: A thread is in terminated or dead state when the run() method exits.
