Java创建多线程和线程安全集合Vector

public class Test {
    public static Vector<String> data = new Vector<String>();

    public static void main(String[] args) {
        for (int i = 0; i < 100; i++) {
            data.add("data" + i);
        }
        
        for (int i = 0; i < 3; i++) {
            Thread t = new Thread() {
                public void run() {
                    String str = "";
                    while (data.size() > 0 && !(str = data.remove(0)).equals("")) {
                        System.out.println(this.getId() + "||" + str);
                        
                        //暂停1秒
                        try {
                            Thread.sleep(1000);
                        } catch (InterruptedException e) {
                            // TODO Auto-generated catch block
                            e.printStackTrace();

                        }
                    }
                }
            };
            t.start();
        }
    }
