7: When a thread obtains the monitor lock on an object, then determines that it cannot continue with its task on that object until some condition is satisfied, the thread can call Object method ________; this releases the monitor lock on the object, and transitions the thread waits to the waiting state.

waitForOtherThreads.

stop.

waitForCondition.

wait.

8: When a thread executing a synchronized statement (or method) completes or satisfies the condition on which another thread may be waiting, it can call Object method ________ or ________ to allow a waiting thread or all waiting threads to transition to the runnable state again.

notifyThread, notifyAllThreads.

notify, notifyAll.

None of the above.

Solution

1. New

A new thread starts its life cycle in the new state. It continues in this state until the program starts the thread. It is too submitted to as a born thread.

2. Runnable

A runnable object stands for a task that is able to execute along with other tasks

3. Main

Java allocates the name main to the thread that runs the main () method, the preliminary thread. Usually see that name in the exemption in thread main note that the JVM\'s default exception handler produces when the starting thread flings an exception object.
