A small Java thread example (like train ticket sales), java thread

Public class MyThread extends Thread {private static int ticket = 100; public void run () {for (int I = 0; I <50; I ++) if (ticket> 0) system. out. println (Thread. currentThread (). getName () + "selling" + (ticket --) + "tickets");} // The main function is a main thread public static void main (String [] args) {MyThread mt = new MyThread (); Thread m1 = new Thread (mt, "window1"); Thread m2 = new Thread (mt, "window2 "); thread m3 = new Thread (mt, "window3"); m1.start (); m2.start (); m3.start ();}}

Similar to the sales of train tickets, different windows sell the same ticket. Two windows cannot sell the same ticket.

JAVA five windows sell 100 train tickets with multiple threads

Well, you can write one for you. Each ticket sales window is 0 ~ Sell a ticket within 5 seconds
