Class Overview
A thread state. A thread can be in one of the following states:
NEW
A thread that has not yet started is in this state.
RUNNABLE
A thread executing in the Java virtual machine is in this state.
BLOCKED
A thread that is blocked waiting for a monitor lock
is in this state.
WAITING
A thread that is waiting indefinitely for another thread to
perform a particular action is in this state.
TIMED_WAITING
A thread that is waiting for another thread to perform an action
for up to a specified waiting time is in this state.
TERMINATED
A thread that has exited is in this state.
A thread can be in only one state at a given point in time.
These states are virtual machine states which do not reflect
any operating system thread states.

Thread.State
BLOCKED
Thread state for a thread blocked waiting for a monitor lock.
A thread in the blocked state is waiting for a monitor lock
to enter a synchronized block/method or
reenter a synchronized block/method after calling
Object.wait
.
Thread state for a thread which has not yet started.

Thread.State
RUNNABLE
Thread state for a runnable thread. A thread in the runnable
state is executing in the Java virtual machine but it may
be waiting for other resources from the operating system
such as processor.

Thread.State
TIMED_WAITING

Thread.State
WAITING
Thread state for a waiting thread.
A thread is in the waiting state due to calling one of the
following methods:
A thread in the waiting state is waiting for another thread to
perform a particular action.
For example, a thread that has called Object.wait()
on an object is waiting for another thread to call
