call Monitor.pulse (x ' x) The freed resource is locked as soon as the feature's thread frees resources.2. Monitor.Wait (XX) implements the thread that called the method to temporarily release the locked resource and let the thread go into the waiting thread queue. So the thread temporarily interrupts the execution of subsequent code after calling the method, and when the thread gets the resource again,will return to the interrupt to continue execution.3, Monitor.pulseall (XX) is Monitor.pulse

Use the top command to dynamically monitor the memory usage of programs with very short running times Solution: Top-d 0.01-N2000-B | grep lzma -D specifies the interval at which top data is collected. The value is 0.01 seconds. -N indicates the total number of statistics. Set this parameter to 2000 to ensure that the top node does not end the statistics during the program running. Grep specifies th
