This article introduces the knowledge of "how to call the lockInterruptibly method to respond to the threaded interrupt method". Many people will encounter this dilemma in the operation of the actual case, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

/ * reentrantlock is used to replace synchronized * because M1 locks this, m2 can only be executed when M1 finishes execution * here is a review of the original semantics of synchronized * * the same function can be done with reentrantlock * it is important to note that the lock must be released manually (say the important thing three times) * if an exception is encountered with syn lock, jvm will automatically release the lock But lock must release the lock manually, so the lock is often released in finally * * you can use reentrantlock to "try to lock" tryLock, so it cannot be locked or cannot be locked within a specified period of time, and the thread can decide whether to continue to wait * * using ReentrantLock can also call the lockInterruptibly method, which can respond to the thread interrupt method, * while a thread is waiting for the lock. Can be interrupted * * @ author mashibing * /

The T1 thread occupied the lock.

Public class ReentrantLock4 {public static void main (String [] args) {Lock lock = new ReentrantLock (); Thread T1 = new Thread (()-> {try {lock.lock ()) System.out.println ("T1 start"); TimeUnit.SECONDS.sleep (Integer.MAX_VALUE); System.out.println ("T1 end") } catch (InterruptedException e) {System.out.println ("interrupted!");} finally {lock.unlock ();}}); t1.start () Thread T2 = new Thread (()-> {try {/ / lock.lock (); lock.lockInterruptibly (); / / you can respond to the interrupt () method System.out.println ("T2 start") TimeUnit.SECONDS.sleep (5); System.out.println ("T2 end");} catch (InterruptedException e) {System.out.println ("interrupted!") } finally {lock.unlock ();}}); t2.start (); try {TimeUnit.SECONDS.sleep (1) } catch (InterruptedException e) {e.printStackTrace ();} t2.interrupt (); / / interrupt Thread 2 waiting} "how to call the lockInterruptibly method to respond to the thread interrupt method".
