Suspend () is a run-time state that enters a blocking state (note that the lock flag is not released). Resume () when restoring state. Stop () means release all.There are deprecated flags on these methods, which indicate that this method is not recommended for use.In general, the Main method main () ends when the thread ends, but there may be situations where the thread needs to be interrupted.

In Java, there are two ways in which a class can invoke another class by instantiating the class, invoking the method of instantiating the object, and invoking it using the Java mapping mechanism. The first method is no longer explained, and the second method uses the following: public class Run { public static void Main (string[] args) {String str = args[0] + "Hello World";System.out.println (str);} } Import Java.lang.reflect.Method; public cla

I saw a friend a few days ago and wanted to execute a piece of code before the main execution. I was not clear at the time, so I did not dare to rush to answer the question, for fear of misleading others. After figuring it out, I found that the post was gone and sweated.
