Java - Thread States

A thread lies only in one of the shown states at any instant:

State	Description
New	a thread that has not yet started
Runnable	thread state for a runnable thread a thread in runnable state might be either: running ready run at any instant of time
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()`
Waiting	thread state for a waiting thread a thread is in the waiting state due to calling one of the following methods: `Object.wait with no timeout` `Thread.join with no timeout` `LockSupport.park` 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 `Object.notify()` or `Object.notifyAll()` on that object. A thread that has called `Thread.join()` is waiting for a specified thread to terminate.
Timed Waiting	thread state for a waiting thread with a specified waiting time a thread is in the timed waiting state due to calling one of the following methods with a specified positive waiting time: `Thread.sleep` `Object.wait with timeout` `Thread.join with timeout` `LockSupport.parkNanos` `LockSupport.parkUntil`
Terminated	a thread terminates because of either of the following reasons: Because it exits normally. This happens when the code of thread has entirely executed by the program. Because there occurred some unusual erroneous event, like segmentation fault or an unhandled exception
