The tryenter () method of the monitor class is similar to the enter () method in trying to obtain an explicit lock on an object. However, it does not block execution like the enter () method. If the thread successfully enters the key area, the tryenter () method returns true. Two of the three overload methods of the tryenter () method use a timeout value as the parameter, indicating that the lock is waiting for the specified time. Let's look at an exa
