How detect and resolve DeadLocks in Java

DeadLocks occur when a thread is waiting for other thread to release a lock, and vice-versa. Global ordering of locks along with lock acquire timeouts and subsequent release of locks can go a long way in avoiding deadlocks.

[@praveenbalasubramaniam4364]

ordering by account number is nice

[@prateekkanujiya9775]

Please add some videos on serialization

[@rakeshroshan9690]

can we do producer consumer problem using thread-local ?

[@josephfernando4867]

Unfortunately there is no method by which specific threads in deadlock state can be terminated so that the program can keep executing. One can only kill the jvm process. If anyone knows a way by which one can terminate a specific thread by it id please share.

[@Kc-nn8mn]

i come to watch this video because there are plenty of stupid interview questions requiring developer to remember everything instead of using the online references.

[@Stoic623]

How to take thread dump in a file in production environment.?
JRE doesn't has any monitoring or analyzing tool.

[@DefogTech]

True. You have to ssh into the production box, and do "kill -3" or use jstack. In both cases it will create a file.
Also, if we have deadlock in production, then most likely application itself won't be able to continue serving clients.

[@mrrishiraj88]

🎉

[@padmakaki1936]

can someone please explain me this statement new Thread(this::processThis).start();

[@shaikshasayyad3217]

It's a simple way of creating Lambdas using Method references. have a look at java 8 lambda features

[@sushmitagoswami2033]

Locking Order won't work in case locks are acquired on items passed externally.

[@vivekpjadhav]

is there a way jvm can clear the dead lock by itself ?

[@DefogTech]

unfortunately no..

[@cforcmputer]

why dont you create your blog
