The following program creates three child threads:
// Create multiple threads. class MyThread implements Runnable { String name; // name of thread Thread t;//from ww w .j a v a 2 s .co m MyThread(String threadname) { name = threadname; t = new Thread(this, name); System.out.println("New thread: " + t); t.start(); // Start the thread } // This is the entry point for thread. public void run() { try { for(int i = 5; i > 0; i--) { System.out.println(name + ": " + i); Thread.sleep(1000); } } catch (InterruptedException e) { System.out.println(name + "Interrupted"); } System.out.println(name + " exiting."); } } public class Main { public static void main(String args[]) { new MyThread("One"); // start threads new MyThread("Two"); new MyThread("Three"); try { // wait for other threads to end Thread.sleep(10000); } catch (InterruptedException e) { System.out.println("Main thread Interrupted"); } System.out.println("Main thread exiting."); } }
