Difference between the timer of swing and util

In general, the utility timer should be used if the required timing function is irrelevant to swing. If the system designed and the scheduled function are closely related to swing, you should consider using the swing timer. 1. Differences between two timers (1) Swing timers use a thread to process all scheduled objects, so they are not suitable for processing a large number of scheduled objects at the same time, while utility timers do not, it provides an independent thread for each scheduled object. Therefore, if the designed system requires a large number of timer objects, the utility timer can be used to meet the requirements. (2) in use, the swing Timer class requires an action object to encapsulate timing, while the utility timer creates a timertask object for each scheduled task, to encapsulate scheduled behaviors.
