class TicketThread extends Thread { private int ticket = 10; @Override public void run() { while(ticket > 0) { System.out.println(getName() + "卖票：" + ticket--); } } } public class ThreadDemo { public static void main(String[] args) { // 两个独立对象，各有10张票，总共卖出20张，数据不共享 TicketThread t1 = new TicketThread(); TicketThread t2 = new TicketThread(); t1.start(); t2.start(); } }

class TicketTask implements Runnable { private int ticket = 10; @Override public void run() { while(ticket > 0) { System.out.println(Thread.currentThread().getName() + "卖票：" + ticket--); } } } public class RunnableDemo { public static void main(String[] args) { // 同一个任务对象传入两个线程，共享10张票 TicketTask task = new TicketTask(); Thread t1 = new Thread(task, "窗口1"); Thread t2 = new Thread(task, "窗口2"); t1.start(); t2.start(); } }

继承Thread无法共享数据；Runnable可多线程共享数据。
