public class SleepReleaseLock {
	public static void main(String[] args) {
		Object lock=new Object();
		SleepReleaseLockA sleepReleaseLockA=new SleepReleaseLockA(lock);
		sleepReleaseLockA.start();
		SleepReleaseLockB sleepReleaseLockB=new SleepReleaseLockB(lock);
		sleepReleaseLockB.start();
	}
}
class SleepReleaseLockEx{
	public void testMethod(Object lock) {
		try {
			synchronized (lock) {
				System.out.println("begin wait!!");
				Thread.sleep(10000);
				System.out.println("end wait!!");
			}
		} catch (Exception e) {
		}
	}
}
class SleepReleaseLockA extends Thread{
	private Object lock;
	public SleepReleaseLockA(Object lock) {
		this.lock=lock;
	}
	@Override
	public void run() {
		SleepReleaseLockEx sleepReleaseLockEx=new SleepReleaseLockEx();
		sleepReleaseLockEx.testMethod(lock);
	}
}
class SleepReleaseLockB extends Thread{
	private Object lock;
	public SleepReleaseLockB(Object lock) {
		this.lock=lock;
	}
	@Override
	public void run() {
		SleepReleaseLockEx sleepReleaseLockEx=new SleepReleaseLockEx();
		sleepReleaseLockEx.testMethod(lock);
	}
}

結果：

begin wait!!
end wait!!
begin wait!!
end wait!!

結論：sleep方法會讓線程處於同步狀態
