1. New state - After the creations of Thread instance
the thread is in this state but before the start() method
invocation. At this point, the thread is considered not
alive.
2. Runnable (Ready-to-run) state - A thread start its
life from Runnable state. A thread first enters runnable
state after the invoking of start() method but a thread can
return to this state after either running, waiting,
sleeping or coming back from blocked state also. On this
state a thread is waiting for a turn on processor.
3. Running state - A thread is in running state that
means the thread is currently executing. There are several
ways to enter in Runnable state but there is only one way
to enter in Running state: the scheduler select a thread
from runnable pool.
4. Dead state - A thread can be considered dead when
its run() method completes. If any thread comes on this
state that means it cannot ever run again.
5. Blocked - A thread can enter in this state because
of waiting the resources that are hold by another thread.
