TIMED_WAITING

enum val TIMED_WAITING : Thread.State

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:

• sleep
• Object.wait with timeout
• Thread.join with timeout
• java.util.concurrent.locks.LockSupport#parkNanos
• java.util.concurrent.locks.LockSupport#parkUntil

WAITING

enum val WAITING : Thread.State

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.
