线程wait，notify机制便笺

public class TestNotify {

	public static void main(String[] args) {

		TestNotify testNotify = new TestNotify();
		MyThread t = testNotify.new MyThread();

		t.start();

		System.out.println("MyThread is start.");
		synchronized (t) {
			try {
				System.out.println("Waiting for b to complete.");
				t.wait();
			} catch (InterruptedException e) {
				e.printStackTrace();
			}
			System.out.println("MyThread is stop.");
		}
	}

	class MyThread extends Thread {

		public int total;

		public void run() {
			synchronized (this) {
				System.out.println("MyThread is running...");
				for (int i = 0; i < 100; i++) {
					total += i;
				}
				System.out.println("fianl total is:" + total + ".");
				notify();
			}
		}
	}
