method called, that is, the method to be executed; args is the method parameter; proxy, what is this parameter? The above implementation of the invoke () method is a standard form. We can see that the proxy parameter is not used here. View the Proxy instructions in the JDK documentation as follows:Java code A

see that B generates two bridge methods, but C does not. In fact, Java generics have an erasure mechanism, so when compiling Class A, all the methods defined in it are represented by the Object type. Therefore, if there is no bridge method, class B does not cover the abstract method in Class A at all. Because of the existence of the bridge

cyclically. The Runnable task we passed is an infinite loop that will run until we stop it. Note that I use the volatile keyword.The main thread first starts thread T1 and then stops the thread using the stop () method.In this example, we have two methods to stop the running of a Thread: Thread. sleep () or TimeUnit. sleep. The TimeUnit class can specify the second (TimeUnit. SECONDS) and the millisecond (TimeUnit. MILLISECONDS. In general, using the sleep ()
