Implement multithreaded thread

Define a subclass subthread to inherit thread:

/** define subclasses, inherit thread * / public class subthread extends Thread {public void run() {for (int i = 0; I < 50; I + +) system.out.println ("run..."+ i); }

}

Test demo class:

/** create and start a thread * create a thread subclass object. After creation, the subclass object calls the method start() * to let the thread program execute, and the JVM calls run * / public class threaddemo {public static void main (string [] args) {subthread st = new subthread(); st.start(); for (int i = 0; I < 50; I + +) system.out.println ("main..."+ i); } }
