GetName () + "sell" + tickets + "ticket"); tickets--;try {Thread.sleep (500);} catch (InterruptedException e) {e.printStackTrace () } public class TicketTest {public static void main (String args []) {SellTicket t = new SellTicket (); new Thread (t, "window 1"). Start (); new Thread (t, "window 2"). Start (); new Thread (t, "window 3"). Start (); System.out.println ("main thread ends") }} after reading this, the article "what are the conditions for the use of java synchronization" has been introduced.
