Title Body

I'm trying to check how wait/notify works in java. Code: public class Tester { public static void main(String[] args) { MyRunnable r = new MyRunnable(); Thread t = new Thread(r); t.start(); synchronized (t) { try { System.out.println("wating for t to complete"); t.wait(); System.out.println("wait over"); } catch (InterruptedException e) { e.printStackTrace(); } } } } class MyRunnable implements Runnable { public void run() { System.out.println("entering run method"); synchronized (this) { System.out.println("entering syncronised block"); notify(); try { Thread.currentThread().sleep(1000); } catch (InterruptedException e) { e.printStackTrace(); } System.out.println("leaving syncronized block"); } System.out.println("leaving run method"); } } Output Returned wating for t to complete entering run method entering syncronised block //sleep called leaving syncronized block leaving run method wait over I was expecting when notify() is executed the wait will be over & System.out.println("wait over"); will get printed. But it seems it only gets printed when t finished its run() .
