Runnable和Thread的一点区别

package Thread.Thread04;

/**

 */
public class TicketDemo {
    public static void main(String[] args) {
        TicketWindow tw = new TicketWindow();
        new Thread(tw, "销售一号").start();
        new Thread(tw, "销售二号").start();
        new Thread(tw, "销售三号").start();




    }

    static class TicketWindow implements Runnable {
        private int ticketNumber=100;
        @Override
        public void run() {
            while (true){
                if (ticketNumber>0){
                    Thread thread = Thread.currentThread();
                    String threadName = thread.getName();
                    System.out.println(threadName+"正在销售第"+ticketNumber--+"张票");
                    try {
                        Thread.sleep(50);
                    } catch (InterruptedException e) {
                        e.printStackTrace();
