16.同步类容器Collections.synchronized

voctor动态数组、同步类容器，底层实现基于：Collections.synchronized

package demo5;

import java.util.ArrayList;
import java.util.Collections;
import java.util.List;
import java.util.Vector;

/**
* Created by liudan on 2017/7/9.
*/
public class MyThread2 extends Thread {
/*同步类容器、动态数组*/
public static void main(String[] args) {
/*final Vector<String> ticksts = new Vector<>();*/

List<String> ticksts = Collections.synchronizedList(new ArrayList<String>());

for (int i = 1; i <= 100; i++) {
ticksts.add("G1001-火车票-G000X" + i);
}

for (int i = 1; i <= 10; i++) {
new Thread("线程" + i) {
@Override
public void run() {
while (true) {
if (ticksts.isEmpty()) break;
System.err.println(Thread.currentThread().getName() + "\t" + ticksts.remove(0));
}
}
}.start();
}

}
}
输出：
