 */
import java.lang.*;

public class Demo implements Runnable {

    Demo() {
        // main thread
        Thread currThread = Thread.currentThread();

        // thread created
        Thread t = new Thread(this, "Admin Thread");

        System.out.println("current thread = " + currThread);
        System.out.println("thread created = " + t);

        // this will call run() function
        t.start();
    }

    public void run() {
        System.out.println("This is run() method");
    }

    public static void main(String args[]) {
        new Demo();
    }
}

输出结果为：

current thread = Thread[main,5,main]
thread created = Thread[Admin Thread,5,main]
This is run() method
