Prefaceafter learning the UML time series diagram, we need to look at the UML collaboration diagram, because the two graphs are complementary. definitiondescribe the relationships between objects of mutual cooperation and only model the relationships between objects interacting with each other. compositionObjectat the same time as the sequence diagram, the collaboration diagram includes three naming methods

Java thread collaboration yield (), java thread collaboration yield Yield (): method definition Calling the yield method will allow the current thread to hand over the CPU permission and allow the CPU to execute other threads.
