This means that when a thread t1 calls t2.join(), then all changes done by t2 are visible in t1 on return. Concatenates an observable sequence of observable sequences. Like the wait() and notify() methods, join() is another mechanism of inter-thread synchronization. Computes the sum of a sequence of nullable.
