notify()喚醒線程，不會立即釋放鎖對象，需要等到當前同步代碼塊都執行完后才能釋放鎖對象?

public class Test3 {public static void main(String[] args) {List<String> list = new ArrayList<>();Thread thread1 = new Thread(new Runnable() {@Overridepublic void run() {synchronized (list) {if (list.size() != 5) {System.out.println("線程1開始等待" + System.currentTimeMillis());try {list.wait();} catch (InterruptedException e) {e.printStackTrace();}System.out.println("線程1被喚醒：" + System.currentTimeMillis());}}}}) {};Thread thread2 = new Thread(new Runnable() {@Overridepublic void run() {synchronized (list) {for (int i = 0; i < 10; i++) {list.add("data" + i);System.out.println("線程2添加第" + i + "個數據");if (list.size() == 5) {list.notify();System.out.println("線程2已經發現喚醒通知");}try {Thread.sleep(1000);} catch (InterruptedException e) {e.printStackTrace();}}}}}) {};thread1.start();try {Thread.sleep(500);} catch (InterruptedException e) {e.printStackTrace();}thread2.start();} }
