Java中的集合與線程的Demo

一、簡單線程同步問題

package com.ietree.multithread.sync;

import java.util.Vector;

public class Tickets {
    public static void main(String[] args) {

        // 初始化火車票池並添加火車票:避免線程同步可採用Vector替代ArrayList HashTable替代HashMap
        final Vector<String> tickets = new Vector<String>();

        // Map<String, String> map = Collections.synchronizedMap(new HashMap<String, String>());

        for (int i = 1; i <= 1000; i++) {
            tickets.add("火車票" + i);
        }

        // for (Iterator iterator = tickets.iterator(); iterator.hasNext();) {
        // String string = (String) iterator.next();
        // tickets.remove(20);
        // }

        for (int i = 1; i <= 10; i++) {
            new Thread("線程" + i) {
                public void run() {
                    while (true) {
                        if (tickets.isEmpty()) {
                            break;
                        }
                        System.out.println(Thread.currentThread().getName() + "---" + tickets.remove(0));
                    }
                }
            }.start();
        }
    }
}
